      The members of the  project team at Battelle's Columbus Laboratories are grateful
for your assistance and cooperation in the performance of this contract,  Your comments
and suggestions have  been  helpful,  particularly those on the content and format of the
summary report.  We, hopefully, have made the necessary modifications in the copies
which have been reproduced and are being transmitted to you herewith.

      An aggressive program for use and evaluation of the developed model is suggested.
It includes:

      (1)  Improving the cost-elements-data bank

      (2)  Applying the model to specific locations and sizes of generation
          facilities.

We would be  pleased to submit a proposal to you at your request for the additional  effort
which is needed.

                                  January 17,  1969
                                     SUMMARY
      In the search for an effective means for decreasing SO2 emissions resulting from
the use of fossil fuels, a number of control techniques have been proposed and are being
investigated.  To permit comparison of the various potential techniques, a standardized
method has been needed.  To this end,  a  cost-utilization model has been developed which
permits the estimation of the incremental cost for control.  Specifically,  the model has
been formulated to apply to large fossil-fuel-burning electric power stations using SO£-
control processes which result in the recovery of sulfur or sulfuric acid as a by-
product.   So that the model will have maximum utility in its present form, provision
has been made for the additional alternatives  of:  remote siting, nuclear generation, and
substitute fuels having lower sulfur contents.

      The model as developed and presented in this report  has been formulated as a
group of  algebraic expressions.  However, emphasis is placed on the use of computa-
tional forms which are provided  to assist in organizing  input data and performing the
required calculations.  These forms are  accompanied by data (tabular, graphical, and
in other forms as well) which permit the  selection and entry of the appropriate numeri-
cal value in the proper location on a form once a specific SO£ control or other alterna-
tive has been  selected. Following the forms  in the proper, described sequence results
in the prediction of the cost of electricity (as  delivered  to the distribution network) which
would be achieved through application of the specified power-generation alternative.
(The costs are not those to the ultimate consumer  since other costs  — such as those for
distribution, billing,  etc.  — would have to be  included.) Also obtained  would be pre-
dicted values  for the amount of sulfur removed, for example.  The form provided for
the summary  of results allows easy comparison of the results obtained for different ap-
proaches to SO2 control for any given service area.

      No attempt has been made  to include in the present model techniques for determin-
ing the "optimum" process for a specified location and size of generating facility.  How-
ever, by the systematic application of the model to numerous alternatives and a set of
locations,  the best alternatives will be  identified.   To illustrate this point,  a series of
computations  for several locations and alternatives have been performed.  Cost of power
delivered to a distribution network varied from a low of 3.67 mills/kwhr  for local gen-
eration in an 800-Mw station serving the  Dallas area using natural gas  as a fuel to a high
of 9.01 mills/kwhr for mine-mouth generation in an 800-Mw station serving the

               BATTELLE MEMORIAL INSTITUTE - COLUMBUS  LABORATORIES

-------
New York City service area.  Costs for control (using the alkalized-alumina process)
ranged from a low of 0.26 mills/kwhr for a 2082-Mw station burning 3 percent sulfur
coal to serve the Northern Indiana area to a high of 0. 53 mills/kwhr  for an 840-Mw
station burning 3 percent sulfur oil to serve the Baltimore area.  For the Northern
Indiana example, the control cost would drop to 0. 18  mills/kwhr if 5 percent sulfur coal
were burned. Costs for control using the Cat-Ox process were also  within this range.
Costs for nuclear generation were predicted as 5.28 mills/kwhr for the Northern Indiana
service area and 5.86 mills/kwhr  for the Baltimore and New York City service areas.
These were the only nuclear-generation examples computed.

      Important indications have been provided by these examples.  First, costs for
nuclear generation appear to be competitive with those  for fossil-fuel generation, par-
ticularly in high-cost areas for fuel and labor.   Second, with currently available
cost information, costs for SC>2 control using processes providing for recovery of sulfur
or sulfuric acid in new,  large,  power-generation facilities should not be expected to ex-
ceed 0.5 mills/kwhr.  Finally,  the use of mine-mouth generation without SC>2 control is
not expected to provide a viable alternative because of the high  cost of transmission.

      It has been concluded that a useful, valid cost-estimating model has been developed
for comparing various alternative  methods for  controlling SC>2 emissions from large,
new, power-generation stations.  However, there are additional needs for a continuing
program to improve the cost data bank and to test further the application of the model to
specific locations and  sizes of generation facilities.  When these  immediate steps have

                                   INTRODUCTION
      The problem of atmospheric pollution over the United States is gradually intensify-
ing,  and one of the major contributors to this problem is the power -generation industry.
Millions of tons per year of noxious gases are emitted by power plants fired with fossil
fuels.  These noxious gases include sulfur  dioxide (SO 2) and nitrogen oxides as major
constituents.  Recently, intensive interest  has been directed at SO 2 as a prime object of
current and future control activities.

      Predictions of the growth of the power -gene ration industry and the fossil -fuel -
fired segment have been made.  For example, the report of National Academy of
Science's Committee on Pollution(l)*  states that "even with the assumption that, by the
year 2000, 50 percent of the U. S. electric generating capacity will be nuclear,  it is
projected that fossil -fuel -fired electric  generating capacity will double by 1980 and re-
double by the year 2000.  As a consequence, emission quantities would also double by
1980 and redouble by 2000. . ."  With regard to SO2 emissions it is further stated that,
for the case of severe but realistic controls, SO£ emissions would be expected to in-
crease by 75 percent by 1980 and by an additional 75 percent by 2000. Even with "con-
trol  at the maximum level that technology will be able to achieve. . .a 20 percent increase
(in SO2 levels) by 1980 but a 20 percent  decrease from that level by 2000. . ." would be
expected.

      Thus, the size of the problem is large, and it implies, to some degree,  the diffi-
culty of the  situation which is faced.   For the Federal Government, the National Air
Pollution Control Administration has the assignment of encouraging and supporting the
development of the necessary control technology.  In  this Federal program, there is a
limit to available funds, manpower, and facilities.  As a result,  only those processes
that  show greatest potential promise for control can be investigated.  For greatest effi-
ciency, early decisions  as to potential promise  should be possible.  It is this capability
for early evaluation and decision which needs to be enhanced and to which this program
has been directed.

      In planning for the development of SO2 -control processes,  two major considera-
tions enter into the decision -making process regarding which processes are likely to be
advantageous:

      (1)  The additional cost of electricity that  results from use of a  specific
              -control process
      (2)  The utility of the 803 -control process in terms of its applicability to
          specific power plants and the implications this has regarding the
          amount of SO£ that will be prevented from entering the atmosphere.

There are other  factors that enter into the development -decision process,  such as the
evaluation of technical feasibility, but this cost -utilization model is concerned with
evaluation of only those factors listed above.  "Benefits" cannot be evaluated at the pres
ent state of our knowledge and, thus, so-called cost-benefit factors cannot be computed.
Arbitrary levels  of SO£  concentration in stack gas will form the basis for the  compari-
sons to be made.

      It should be noted here that the model also contains provision for evaluating the
cost and utility implications of other approaches to SO2 control other than the treatment
of flue gas.  The use of low-sulfur coal can be evaluated by suitable adjustment of fuel
costs, and the remote-location approach can be costed by adjustment of transmission,
fuel,  and other cost elements that depend upon location.  Comparison with costs achieved
by nuclear generation is also possible.

                     MODEL ORGANIZATION AND PROCEDURE
                            General Description of Model
      The model developed in this program is designed to enable the analysis of the in-
cremental cost of approaches to controlling SO2 emissions of large fossil-fuel-burning
electric power plants.  The model also contains provision for  evaluating the costs of
approaches to SO2 control other than the treatment of flue gas.  For example, the use of
low-sulfur coal can be evaluated by  suitable adjustment of fuel costs, or a remote-siting
approach can be considered by inclusion of transmission costs and the adjustment of fuel
and other  cost  elements that depend upon location.  The incremental cost is ultimately
expressed in terms of a "mills/kwhr" value above that for power generation without an
SO2 -control approach.

      The model is concerned with power-generation costs only, except in the case when
transmission costs are included because  remote siting is being considered as an alter-
native approach to SO2 control. The costs developed,  then, are not those to the  ultimate
consumer, since other costs — such as those for distribution — would have to be
included.

      The model is formulated as  a  group of algebraic expressions. However, emphasis
is placed on use of the forms that are also provided to assist in organizing input  data and
performing the required calculations.  Use of these forms helps to insure that the  re-
quired cost elements are  considered,  that the proper computations are completed, and
that records are made of the analysis. The form provided for the summary of results
allows easy comparison of the results obtained  for different approaches to SO2 control
for the power plant of interest. The input data  are obtained from curves showing "cost-
estimating relationships" (CER's) or tables provided in the section on Cost Elements for
Fossil-Fuel-Burning Power  Plants.

      Costs are regarded as falling  in the two broad categories - nonrecurring and re-
curring.  Nonrecurring costs are those required for initial equipment installation and
start-up and, if applicable, the cost of additional-equipment installation that may take
place after the plant is in operation; for example,  an additional power-generation unit
might be installed after several years of operation of the first unit.  Recurring costs
are those  costs for fuel, operations, maintenance, and other annual expenses.  Deter-
mination of the nonrecurring and the annual recurring costs permits the analyst  to gen-
erate plots such as those  shown in Figure 1.  The  nonrecurring cost is shown as an
initial cost at the start of the first year of operation,  and the recurring-cost cumulative
total is  plotted for each subsequent  year of the time period of  interest.

      Use of the nonrecurring-recurring  cost approach avoids the problems associated
with determining the  annual charges that  arise because  of the  initial investment.   How-
ever, in order to determine  an incremental "mills/kwhr" value that reflects both non-
recurring and recurring costs, it is necessary  to "annualize" the nonrecurring costs.
This requires consideration  of "financial factors"  such as the cost of capital, the period
and type of depreciation,  and income-related taxes.  Provision is made in the model for
including such  "financial factors" as an annual cost that is added to other recurring
costs.  This  sum of the annual costs divided by the sum of net energy  available for dis-
tribution for the planning  period provides the desired "mills/kwhr" value.

      The model permits analysis on  a yearly basis or on a cumulative total basis for a
specified planning period.  In cases where the annual costs do not vary, the  analysis of
only the nonrecurring cost and  1 year's recurring cost is  required.  However, if
changes in "capacity factor"*,  power-generation capacity, fuel characteristics,  or  other
factors are expected to occur after the first year of operation,  then annual costs must
be adjusted accordingly.   The model makes provision for  this by allowing for annual
entries of recurring costs.

      The concern of this  model is with future costs,  and  there are many problems
associated with translating past cost experience into a future estimate.  To avoid some
of these problems,  future cost  estimates  are made in terms of current dollars.  Also,
provision has been made for the adjustment of historic construction cost data to  current
dollars,  (see p 40.)

      This program has not been primarily concerned with generating the detailed in-
stallation, operation, and maintenance costs for SO£ -control equipment and  the asso-
ciated by-product plant, although a limited amount of work has  been performed in this
area to help guide model-development efforts.   The costs for the 50% -control approach
are entered as increments to the nonrecurring and recurring costs of power-plant con-
struction and operation.  This is accomplished  by one of the following procedures:

      (1) The nonrecurring and recurring costs for the SO2 -control equipment
          and by-product plant  are entered in combination or separately on the
          appropriate forms to enable addition to the nonrecurring and  recurring
          costs of the power plant.  If the nonrecurring and recurring costs  for

          the power plant without SO2 control are influenced by the use of SO2-
          control devices — for example, if boiler-plant modifications are
          required — then these costs are adjusted accordingly.   Provision is
          also made for allowing credits for the sale of by-product.

      (2)  If a fuel change is used for SO2 control,  the incremental cost is  de-
          termined by evaluating the recurring fuel costs  resulting from changes
          in fuel price and consumption,  the latter being influenced by possible
          changes in heat rate of the power plant and heat content of the fuel.

      (3)  If remote  siting is considered as  an  option to  the use of an SC>2 control
          process, then the nonrecurring and recurring costs for power trans-
          mission are considered.

      Provision is made in the model for determining the  total weight of sulfur contained
in the fuel burned.   If the analyst knows or  assumes an  efficiency of SC>2 removal of the
SO2-control process, he can then compute  the amount of sulfur removed that would
otherwise be released to the atmosphere as SC>2.  Such  data, along with the incremental
costs required  for the SC>2 -control process, then permit the analyst to calculate the cost
per ton of sulfur prevented from entering the atmosphere as SC>2.

      An important consideration in the model is the time period to be examined in the
cost analysis.  Ideally,  cost data starting with the first significant research expenditure
for the SO2-control  process along with all other nonrecurring and recurring costs for
the power plant and  the SC>2-control-process facilities — with credits for the sale of by-
products — and continuing throughout the life of the power plant would be considered.
However, this ideal must be tempered with the realization that cost uncertainties in-
crease with the  extent of the time horizon.  For this reason, the position taken is  that
cost projections beyond  a ZO-year plant operation period are not  meaningful in terms  of
evaluating the relative economics of SC>2 -control-process alternatives.

      Additional discussion of the background and other considerations that influenced
the structure of the  model are found in Appendix A.
                                   Model Details
      The details of the model are described below.  This description is organized
around a discussion of the equations used for calculations and the forms that have been
developed for the analyst to use in orgai....zing input data,  performing the required cal-
culations and summarizing results.  Reference is also made to the appropriate section
of the report for obtaining the required input data.

      Figure 2, Simplified Flow Chart of Model,  provides an overview of the type and
sequence of computations used in the model. The applicable equations and forms used
for each calculation are indicated.  Table 1 lists the forms provided for the analyst,  and
Table 2 supplies a  summary of the equations used and definitions of symbols in the equa-
tions.  The figure number for each form used is indicated, and the text accompanying
each figure should  be referred to in order to understand what alternative computations
can be made  according to the type of available input data.  Some of the terms of the
equations shown in Table 2 are set equal to zero according to the requirements of the

SUMMARY OF RESULTS OF ANALYSIS
particular analysis; for example,  Equation (1),  which is used to determine the sum of
nonrecurring costs (Tj^jj^), would be used with C (SO2 -control -process equipment costs)
and B (by -product -plant construction costs) set equal to zero in the case where an
    -control process is not applied.
      In general, the analyst must first establish the nonrecurring and recurring costs
of the power plant without an SO2 -control approach.  The cost analysis is then repeated
for the various control options of  interest.  By "annualiaing" the nonrecurring costs,
adding these to the recurring  costs, summing the resultant for the planning period,  and
then dividing by the total electrical energy made available for distribution during the
planning period, a  "mills/kwhr" value is obtained.  This value for the various control
options can be compared to that for the power plant without SO£ control — the difference
in these values is  an overall incremental cost for SO2 control.

      The data generated also permit the calculation of a dollar per kilowatt value on the
basis of nonrecurring costs and the nameplate generating capacity of  the power plant.
Another calculation provided for is that to determine the cost per ton of sulfur removed
that would otherwise  enter the atmosphere as
      A capability required of this model is to permit the analyst to introduce incre-
mental costs for SO£ -control approaches.  This is accomplished by introducing nonre-
curring and recurring costs as entries in the various forms to be discussed.  The ana-
lyst has considerable freedom in the amount of detail shown for  such  incremental costs.
For example, he can enter separate costs for the operations,  maintenance, taxes (non-
income), and insurance when entering recurring costs for the SO£ -control equipment

and by-product plant; or he can use one cost entry that covers all recurring cost ele-
ments for both the control equipment and by-product plant.  This flexibility is consid-
ered desirable in anticipation of the types of analyses expected to be of interest.

      It is worthwhile to point out here some of the important possibilities the analyst
should have in mind when performing the analysis:

      (1)  The application of an  SC>2-control process may require modification
          of the power-plant design, and the analyst should consider whether
          this will have an impact on nonrecurring  costs for the power plant.
          Fuel changes may also affect these costs.

      (2)  If the  recurring costs for the SO£ -control equipment and by-product-
          plant operation do not include the cost of  electrical energy used,  then
          this energy should be subtracted from that available for distribution.

      (3)  Fuel consumption  should be adjusted to allow for any changes in heat
          rate resulting from the  application of the SO2 -control process.

Figure 2 introduces these considerations by asking questions at the appropriate place in
the analysis.
Forms

      The forms provided are designed to assist the analyst in organizing input data and
performing the required calculations.  Each line  item on these forms reminds the ana-
lyst of what is needed to complete the analysis.  The Data  Source column provided on
several of the forms shows how or where the entry for a specific line is  determined.
Where appropriate,  the completed forms also provide a  good  record of what was consid-
ered or ignored in a particular analysis.  As shown in Figure 2, each analysis  requires
a Form A, Analysis Identification and General Power Plant Data and a Form S, Sum-
mary of Results of Analysis.  The number and type of other forms used is determined by
the number of SC>2 -control options considered.

      Provision is made on each form for analysis  identification, and the entry of notes
and other information that is expected to assume  increasing importance as analytical re-
sults accumulate and the  need develops to recall the details of various analyses.

     Now consider the details regarding the calculations and the completion of each form.


Analysis Identification and General Power-Plant Data

      Form A, Analysis Identification and General  Power-Plant  Data (Figure 3),  is  used
to identify the analysis and to provide general data  regarding  the power plant, indicate
the planning period of interest,  and specify what SC>2-control  processes are being con-
sidered.  The nameplate  generating capacity of the power-generation units is shown in
the form, and provision is made for  showing when the initial and subsequent power-
generation units will be placed in operation and when construction will start, the latter
time being of interest when the analyst must consider the availability date of a SC>2 -
control process.  The capacity factor assumed is also shown  on  this form, but if it is
desirable to vary this during the planning period,  this is shown on Form  E(see page 21).

The type or types of fuel are identified.  (If more than one type of fuel is used, the frac-
tion of time each type is used must be indicated.)  The permissible SC>2 concentration is
shown along with the percentage of sulfur removed.

      Other entries are for bookkeeping purposes, such as a list of the various forms
used in the particular analysis.
Plant Construction and Start-Up Costs

      The total nonrecurring construction and start-up costs  (Tjg^) are determined from
the equation

                                     P + S + C + B + T,                           (1)

wherein the following definitions apply:

                  Symbol    	Definition	

                     P      Power-plant construction cost

                     S       Start-up cost

                     C      SO2-control-process equipment cost

                     B      By-product-plant construction cost

                     T      Transmission-facilities construction cost

Form NR,  Plant Construction and Start-Up Costs (Figure 4), provides a format for ac-
cumulating these costs.  In addition, the costs for the power-plant subsystems that
determine power-plant construction costs are listed on this form.  These subsystems
are defined the same as  in the Uniform System of Accounts published by the Federal
Power Commission  (see Reference 2, p 43).  This is done  to facilitate use of data pro-
vided to the Federal Power Commission in this format.  Also,  data  regarding these sub-
system costs may be needed because of cost revisions that result from the need to mod-
ify power-plant subsystems when installing SO£-control-process equipment. However,
in those cases  where only the overall power-plant cost is known or of interest, only the
entry for the total cost of the power plant (P) is entered  on the line Power Plant Sub-
total shown on  Form NR.

      C and B or T may  be  set equal to zero in specific analyses according to the  option
being analyzed. A value would be used for T in the case  where the remote-siting  option
is being considered.  Only the subtotal for C + B is shown on Form NR for those cases
where C and B are not costed separately.

      Start-up  costs (S)  have been included in the nonrecurring costs to remind the ana-
lyst of their possible importance in the cases where SO2  -control processes are first
applied to large power plants.  However, data regarding  start-up costs are not yet
available.

      Data regarding plant-construction costs are discussed  in the section on Initial
Plant Costs.  Transmission-facilities construction costs are discussed in the section on

Transmission Costs.  SC>2 -control process equipment and by-product-plant construc-
tion costs are discussed in the section on Sulfur Dioxide Control Devices.
Transmission-Facilities Construction Costs

      If the remote-siting option is to be considered, then the nonrecurring and recurr-
ing costs for transmission facilities should be included in the analysis.  Form T, Trans-
mission Facilities Construction Costs (Figure 5), provides for the analysis of these
costs. Note  that two approaches are allowed for in the computation of nonrecurring
transmission-line costs.  The first is based on the use of dollars-per-mile data.. The
equation used to compute the nonrecurring cost for transmission facilities (Tj) in this
case is                     , .

                             T   = I + E + M,D, + M2DZ '                          ^

wherein the following definitions apply:

                       ence (2), p 54]

             E       Cost of station equipment [ FPC Account

                       lines

             M?      Number of miles of underground transmission
                       lines

             D_,      Cost per mile for underground transmission
                       lines

If there are significant  differences in the cost of various sections of overhead or under-
ground transmission lines,  then additional MxD terms can be included to reflect this
situation.  The sum of the M-terms should add up to the total transmission distance.

      Because of the nature of data presently available, cost elements I and E are con-
sidered as one cost  and are entered on the "Terminal and Other Equipment" line of
Form T.  Data for these costs are discussed in the section on Transmission Costs.

      If the case  should arise where per-mile costs for transmission lines  are not avail-
able or considered inadequate, then it may be necessary to evaluate the component costs.
This  can be done on the basis of FPC account numbers [ Reference (2), p 54] , and
Form T makes provision for this alternative  calculation.  The line items shown  under
Alternative Transmission Facilities Cost Computation are defined in detail on pp 54-55
of Reference (2).  However, the cost-per-mile approach to costing is more convenient,
and the component-costing approach is included only to provide the analyst  with  an alter-
native if cost-per-mile data are lacking.

      The recurring costs for transmission facilities  — operations,  maintenance,  taxes
(nonincome), and insurance are entered in Form R, Recurring Cost Summary.  (See
section on Recurring Costs.)
Energy Generated and Energy Available for Distribution

      In order to determine the fuel consumed,  it is necessary to calculate the total en-
ergy generated.  Also, in order to calculate the mills/kwhr cost for energy delivered to
the distribution network, it is necessary to determine the energy available for distribu-
tion as determined by the energy consumption within the power plant,  energy require-
ments of the SO2-control equipment and by-product plant, and the energy losses in the
transmission equipment, if remote siting of the power plant is  to be considered.

      The total energy generated during the i   year is calculated by the following
equation:
                               .= 8.766 x 10~4 x Y. x PN .   .                        (3)
Terms of the equation are defined as follows:

            Symbol    	Definition	

              E       Total energy generated, billions of kwhr

              Y       Capacity factor*,  %

              P       Nameplate generating capacity, Mw

The 8.766 x 10"""* factor allows for the number of hours in the year and adjusts for the
units used.  The values  calculated for E-p j are entered  on the appropriate fuel-
consumption summaries  (Form FC, FO,  or FG — see following section) to enable com-
putation of total fuel consumption.  The energy calculations are made by use of Form E,
Energy Generated and Energy Available for Distribution (Figure 6).

      The calculation of energy available for distribution is based on the following rela-
tionship for the i1-*1 year:


                 ENET,i = ET,i ~ EPP, i ~ ESCP, i  ~ EBPP, i ~ ETR, i  '             (4)

The terms of this equation are defined as follows:
 'Capacity factor is defined here as 100 times the ratio of energy generated per year to the product of nameplate generating
 capacity times the number of hours in the year (8766 hx/yr).

      Provision is made for calculation of energy available on an annual basis in order
to accommodate the installation of additional generating capacity or a change in capacity
factor after the first year of operation.  However, it is expected that many cases will be
analyzed by use of an average value throughout the planning period. The calculation of
energy on the basis  of the above equation implies that the electrical -energy require-
ments for SC>2 -control and by -product -plant operation have been taken into account, so
the cost of this energy should not be added to the recurring costs assigned to the SO2 -
control process and by-product plant.  However, the analyst has the option of including
the electrical-energy charges in the recurring operations costs for the SO2 -control
process and by -product -plant operation,  but the Eg^p ^ and Egpp ^ terms should be
omitted from the evaluation of PjsfET i "* ^is  case.

      The heat  rate  (Btu/kwhr) data used to  calculate fuel consumption  and costs is
based on net generation.  This means that the  fuel costs for internal power consumption
within '.he plant are  allowed for,  so,  further consideration is not given  to energy con-
sumption within the  plant when heat -rate  data of this type are used. Form E contains a
line Other  Losses that can be used to subtract out energy consumed within the power
plant, if such data become available.  However, if this  is done, care should be taken to
adjust the heat  rate  accordingly.


Fuel  Consumption, Cost, and Sulfur Content

      It has been reported that fuel costs accounted for  78 percent  of annual production
expenses in 1966 [ Reference (3)] ; hence, this is a major recurring expense item.  Also,
the use of low-sulfur fuels is a possible alternative to installation of an SO2 -control
process, but this usually implies higher  fuel expenses,  so the  comparative costs require
evaluation.

      Annual fuel costs for the i   year (F^)  are found by use of the following expression;

                            F. = K x C. x E^  . x H. x U."1   ,                       (5)
                             i        i    T,i    i    i    '

where K is a constant representing the multiplier required to adjust the units used for
the other factors in the equation.  The  other factors are defined as follows:

If oil is burned,  U^ is expressed as Btu/gal; for gas,  Uj is expressed as Btu/cu ft. Note
that the forms provided for calculation of fuel costs also make provision for the use of
fuel costs stated in terms of I/million Btu.  If more than one fuel is used  at a plant,
then separate calculations for  each fuel •would be made on the basis  of percent of total
energy generated by each fuel.

      Form FC, Coal Consumption and Cost and Sulfur Content Summary (Figure 7), is
provided for  the calculation of coal costs on an annual basis.  (Forms FO,  Figure 8, and
FG, Figure 9, are for oil and  gas, respectively.)   By suitable input-data adjustments,
it is possible to determine the effects on recurring fuel costs of changes in capacity
factor,  incorporation of additional generating  units after the first year of operation, and
changes in the cost and heat content of the fuel as a function of time. However, in many
cases, it is expected that it will be adequate to use an average value that applies through-
out the planning period considered.  The form used for calculating fuel consumption and
cost is also a convenient place to calculate the amount of sulfur contained in the fuel.
Provision is  made for this calculation  on Forms FC and FO.  (The  sulfur  content of gas
is usually considered to be negligible. ) The weight of the sulfur in  the fuel consumed
during the  i*h year is obtained from the relationship:

                            'W- . = W_ .  x W_ . x 10~2  .                         (6)
                               S,i     P,i    F,i

             W        Sulfur content,  weight  percent

             W        Weight of fuel consumed, tons

If sulfur weight  is to be  given  in long tons, the weight obtained by this expression  is
divided by  1.12.

      The Energy Generated entry on Forms FC,  FO, and FG is obtained from Form E.
The calculation  of fuel consumption, cost,  and sulfur content then proceeds by perform-
ing the  arithmetic operations indicated on the form to complete each successive line.

      In the case of coal, the cost should be that for "as burned" as distinguished  from
"fob plant".  This distinction is made because the fob plant cost  of coal is the mine
price plus  freight charges,  while the as-burned cost includes the cost of handling  to
place the coal in the  boiler  room bunkers; also, the as-burned cost includes a debit or
credit for ash disposal. However,  the as-burned  prices  shown are also influenced by

the method of pricing according to whether the coal is used directly or from stockpiles,
and this might result in reported as -burned costs being lower than fob plant costs [ see
Reference (4)] .  As -burned cost data should be used wherever possible, but if not avail-
able,  fob  plant costs can be used.  The analyst should note such cases on Forms FC,
FO, or FG.

      If the cost of coal at the mine mouth is known, then transportation charges must
be added to obtain the fob plant cost.  The following expression is used to compute the
cost per ton of coal for the i^h year;
A similar equation would be used to calculate oil costs.  The terms of the above equa-
tion are defined as follows:
Symbol    _ Definition

           Fob plant cost per ton o

           Cost of coal at mine,  $/ton

             D        Distance from mine to power plant, miles

             T        Transportation charge,  $/ton-mile*

The value of Tp when adjusted to become an as -burned cost  would then become the
value for C in Equation (5).

      The importance of fuel costs makes it desirable to carefully consider the impact
an SO2 -control process will have in terms of the amount of fuel that •will be consumed
to produce the  same amount of energy.  An SO2 -control process can conceivably affect
the heat rate or lead to greater electrical energy consumption within the plant.  When
these cases are identified,  suitable allowance should be made  in fuel consumption by
altering the heat rate; or, in the case of increased electrical energy consumption, the
amount of power delivered to the  transmission point should be decreased, the result
being an increase in the cost of energy for distribution. The electrical -energy require-
ments for the SC>2 -control -process equipment and the by-product plant are allowed for
in the calculation of net energy available for distribution (page 20).

      Data regarding fuel costs are given in the section on Fuel Costs and Heating
Value .
      Fuel Changes.  If more than one fuel is burned, then it is necessary to complete
more than one form for fuel consumption, cost, and sulfur-content determination.  The
most direct way to accomplish this is to apportion the capacity-factor entry on Form E
according to the percent of time that each different fuel is burned.  The appropriate
number of Forms FC,  FO, or FG are then completed to determine the apportioned fuel
cost and sulfur content. Each of these separate results  for costs would then be com-
bined to give the total annual fuel costs entered on Form R.  The separate sulfur con-
tents must then be combined to obtain the total sulfur, but no special form is provided
 *These charges are sometimes expressed in mills/ton-mile.

for this — an appropriate note on the fuel-consumption forms used should call attention
to the need for this calculation and its location on an attachment provided by the analyst.

Recurring Costs

      Aside from annual fuel costs, the other  recurring  costs of interest are the opera-
tions and maintenance costs for the power plant  and associated SC>2-control-process
equipment, the transmission facilities,  and the by-product plant. In addition, the annual
taxes (nonincome) and insurance should be  included in these costs.  Also, annual credits
should be allowed  for the sale of by-product.

      The expression used to assess total recurring costs (T^ ^) for the i"1 year is
                      T    = F. +  )  (O, + M. + T. + I.)   - C.  .

      (2)  If the recurring costs for the SC>2-control-process equipment and by-
          product plant are not being analyzed separately, then entries are made
          in the process-equipment section only.

      (3)  If desired, the components of the SC>2-control process and/or by-
          product-plant  recurring costs can be ignored and only the total
          entered, this being done when the analyst's interest is only the deter-
          mination of the effects of incremental increases in costs.

      (4)  Form R allows for a 20-year planning period, but the period of interest
          can be varied  according to the requirements of the analysis.

      Some of the reasons for  allowing for possible annual variations in recurring costs
have been discussed previously.   In addition, note that in the calculation of annual in-
come from by-product sales, it is possible to vary the sales price realized if the analyst
wants to evaluate the implications of, say, future price decreases.
Results of the Analysis

      With the  data generated by the completion of the previously discussed forms, it is
possible to obtain the results of the analysis.  Form S, Summary of Results of Analysis
(Figure 11),  is used for this purpose.  This form provides for the entry of results for^
the power plant without SC>2 control and for the SC>2 -control options considered.  The
appropriate options are  noted by the analyst at the top of the unlabelled  columns (see
Form S).  Depending upon the specific problem under  consideration, the analyst would
be interested in determining the nonrecurring and recurring costs for the power plant
for one or more of the following cases:

      (1)  Without SO2-control measures

      (2)  With various SC>2 -control-process equipment and by-product plants

      (3)  Using low-sulfur fuels

      (4)  Remotely sited.

Analysis of the first case would be performed in all analyses, since this provides the
basis for cost  comparisons.  The evaluation of more than one type of SO2-control-
process equipment and by-product plant may be of interest.

      Provision is made on Form S for the calculation of the  cost per unit nameplate
power-generating capacity in terms of dollars per kilowatt.   The entries  on Form S are
direct in meaning, and the terms used are as  defined  in the previous discussion of the
forms referenced in the column, Data Source.  Note that each line entry on Form S  has
the source of data indicated according to the form on which it is located.  The Data
Source column also shows the required arithmetic operations.  The  percentage value
that is used to obtain the entry on Line 5 of Form S  is discussed in the following  section.

      Form S also provides for the tabulation of  data regarding sulfur removal.  Al-
though this model is not concerned  with determining the efficiencies and the resultant

amount of sulfur removed by various SC»2 -control processes, the analyst would presum-
ably generate such data on the basis of the characteristics of the control process under
consideration and  the amount  of sulfur in the fuel.  After determining the amount of sul-
fur removed during the planning period and the cost differences  between the plant with
and without SOz control, the incremental cost for sulfur removal could be determined in
terms  of mills/kwhr.  These  values for the different SC"2-control approaches of interest
are obtained by subtracting the costs shown on Line 8 of Form S for the power plant
without SO£ control from the corresponding values for the SC>2-control options consid-
ered, and the result is entered on Line 9.

      The incremental cost per ton of sulfur removed is also of  interest.  This value is
obtained  by taking the total of the recurring and annualized nonrecurring costs (Line 6,
Form S)  for the SC>2 -control option case of interest and subtracting the same total for
the power plant without SC"2 control.  The cost differences obtained are divided by the
total sulfur removed by the process.  The result is then entered on Line 12 of Form S.

      Note that the above discussion has been in terms of the totals for the entire plan-
ning period. However, if there is no significant annual variation in any of the values of
interest, the analyst has the option of working with the values for the first year only.
This approach will provide the same values for mills/kwhr and  $/ton of sulfur.


      Annualized Nonrecurring Costs.  In order to obtain a value of mills/kwhr that re-
flects both nonrecurring and recurring costs, it is necessary to "annualize" the non-
recurring cost for the planning period.  By doing this, it is possible to obtain a mills/
kwhr value that provides a single number for the analyst to consider.  However, the
analyst should not forget the importance of the separate nonrecurring cost,  since this
provides important information regarding the initial investment  required.

      The annualization of nonrecurring costs is based upon application of a  percentage
value that includes consideration of financial costs, depreciation, and income-related
taxes. These costs are discussed in the section on Carrying Charges — Treatment of
Financial Costs,  Depreciation,  and Taxes.  Table 21  in that section provides a tabula-
tion of annual carrying charges that would be used to  annualize the nonrecurring costs.
For example, if the "rate  of return" is assumed to be 7 percent and the depreciation
period is 20 years, then the U.S.  average value used would be 13.46 percent.


      Graphic Presentation of Results.  Aside from the tabulation of results found  in
Form  S,  graphic presentations are of interest.  Plots of cumulative costs  such  as  those
shown in Figure 1 can be generated from the nonrecurring and recurring cost data. In
addition, on the basis  of the total sulfur content of the fuel and the efficiency of the  SC>2-
control process,  it would be possible to generate curves showing the cumulative total of
SO2 released to the atmosphere with and without SO^-control processes.  Figure 12
shows such a plot for the case where two different SO2 -control processes are operated
at the  same efficiency.  If the costs shown in Figure  1 apply, then Process A would be
more attractive than Process B from a cost standpoint.

                           Subsystem and Component Costs
      The cost elements previously discussed have been primarily concerned with ag-
gregate costs at the systems level.  Exceptions have been made on Form NR,  Plant
Construction and Start-Up Costs, and Form T, Transmission Facilities Construction
Costs, and this has been done only because of the  convenience.of showing alternative
subsystem cost computations on the  same form.  To the extent possible the analyst
should work with system-level costs in order to avoid the time-consuming  effort to do
detailed costing;  however, cases may arise where it is in order to examine subsystem
or component costs.  For  example,  the incorporation of the  SO2 -control process may
require modifications of power-plant equipment.   If these are extensive, then  the im-
pact on subsystem or component costs for the power plant may require evaluation.

      The subsystems of the power plant are listed on the previously mentioned Form
NR.  Components of these subsystems are listed in  the FPC publication, Uniform Sys-
tem of Accounts  Prescribed for Public Utilities and Licenses. (2)  For example,  on
page 45 of Reference (2), the components of the boiler-plant subsystem are listed as
follows:

       (1)  Ash-handling equipment
       (2)  Boiler feed system
       (3)  Boiler-plant cranes  and hoists

                                COST ELEMENTS FOR
                       FOSSIL-FUEL-BURNING POWER PLANTS
      The data for the calculation of costs are partially in the literature and partially un-
available, and quality varies from very accurate accountant reports to educated guesses.
For the electrical system there is a large body  of previous cost data which has been used
for preparing cost-estimating  relationships.  For the sulfur control devices,  only a few
speculative  estimates of costs are available.  These estimates  were then developed into
cost-estimating relationships by the use of Lang factors and exponential functions.

      The cost data for the electrical generating plants are published annually by the
Federal Power Commission (FPC) in sufficient  detail for the purpose of evaluating possi-
ble utility-rate impacts through the model and for obtaining cost-estimating relationships
for estimating costs of new plants  and fuel,  operating, and maintenance expenses.   The
Bureau of Mines  publishes extensive data on fuels.  The FPC has published data on
transmission-line costs.   The cost data for the  sulfur-control devices are the least accu-
rate because no operating experience is available.   Katell's estimates have generally
been used for purposes related to the use of the model.

      Cost-estimating relationships  have been developed to represent the capital cost,
the annualized costs, and  the operating costs.  In this report, capital costs are called
nonrecurring costs and operating costs, recurring costs.
                                   Initial Plant Costs
      The initial plant cost includes the costs associated with the construction of a-gen-
erating plant up to the time it is generating power.  Since this model will be used with
unfinished plants or proposed plants,  a method is needed for estimating the initial cost.
The  cost of the plant depends upon the geographical location of the plant and upon  the fuel
to be burned.  Coal-fired plants are more expensive than oil- or gas-fired  plants because
of the coal-handling equipment  needed. Coal-fired plants can be converted to oil  or gas
firing with minimal additional cost, and the cost of a change  from oil to gas or vice versa
is also minimal.  The initial cost of the plant is the major part of the capital investment
and therefore the accuracy of this  estimate will have a significant but lesser percentage
effect on the accuracy of the final costs.  Interest  charges and amortization of the plant
cost usually account for about 50 percent  of the overall cost of electricity at the generat-
ing station.

      The construction costs of steam-electric plants is published annually by the Federal
Power Commission (FPC). ^ '  Unfortunately, the costs  are presented for all units in  a
station rather than for the individual units. Although the cost of an individual unit could
be determined by comparing the station cost of the year previous to startup of a new unit
with the cost of current year,  for the present purpose it appears adequate to consider
only the costs of new stations.  The costs  of large, new, coal-fired generating stations
which started operation between I960 and  1965 are plotted in Figure 13.  Cost data before
I960 cannot be related to these costs  because of changes in technology and inflation.

      It has been suggested that oil- and gas-fired units are only 80 percent of the cost of
a coal-fired unit of the same capacity. (5)  Regional cost variation can partially be

      Costs regionally corrected to a cost index of 1200 and the cost of oil- and gas-fired
units increased by 25  percent (1/0.8) are plotted in Figure  14.  The  scatter in  these costs
is only somewhat less than the scatter in costs shown in Figure 13.

      With a few exceptions, the construction costs of units larger than 300 Mw fall within
25 percent of the line  shown in Figure 14. Since bid prices often vary by this amount,
the correlation is probably as good as might  be expected.  The Eddystone plant, plotted
at a cost of $240/kw,  was a plant of a radical new design where an exceptionally low heat
rate was obtained at the expense of high  capital cost.  Other variations are  caused par-
tially by some tradeoff in heat rate against capital  costs and by some randomness.

      The regional correction appears to be quite good. However, the costs are for
metropolitan  areas, and the costs  for nonurban areas are not available.  The cities listed
in the cost index are scattered,  and often it is difficult to decide which cost index to use.
It is suggested that the cost index for the nearest city be used.

      The difference in cost between gas- or oil-fired plants and a. coal-fired plant is
based on the additional cost of coal-handling equipment.  The difference in costs is ap-
parent when plant costs are examined.  Oil-fired plants are sometimes considered to
cost a few percent more than gas-fired plants,  probably because of the storage facilities
required for oil.  This difference in cost is minimal, however,  and should be ignored in
using these  values in the model.
Recommended Values

      It is  recommended that the cost of a plant be estimated using the Engineering Cost
Index of the nearest city in conjunction with the curve shown in Figure  14, i.e.,  multiply
the appropriate value read from the curve by the  ratio of the cost index (value from
Table 3, or a more  current value) to 1200, the normalizing value. If the unit will not
need coal-handling facilities, because oil or gas will be the fuel, this predicted cost
should be modified by multiplying it by 0. 8.


                               Operation and Maintenance


      The operation and maintenance expenses are usually separated from the fuel cost,
and this procedure is followed in the model.  Operation and maintenance expenses amount
to about 10 percent of the cost of electricity at the generating station; hence,  sensitivity
of results to these values is less than that to fuel costs and capital costs which represent
a higher percentage of total generation cost.

      Operation and maintenance costs are published annually by the  Federal Power
Commission^) for most large power plants.  These costs  are plotted against the initial
cost of the generating station in Figure  15.

      Operation and maintenance costs for  a station normally are expressed in mills/
kwhr.  A good correlation is  observed in Figure  15, where operation and maintenance
costs for new plants are plotted as a function of the initial  cost of the plant.   Changes in
operation and maintenance costs are seen to be associated fairly well with changes in the
$/kw first  cost of the unit.  This is a result of two  relationships.  A  given generating unit
which is double the size of another will not require twice the operating and maintenance
personnel.  The larger unit will have the same number of boilers, turbines,  and gener-
ators as the  smaller one and is likely to have a similar number of burners, pumps,  and
controls.   Only the size of each will be larger.  Thus, while more labor will be involved
in repairing  a larger pump,  it should not be double. The second relationship is that as
gene rating-unit sizes double, their first costs usually do not.  Therefore, it  would be
expected that the operating and maintenance expenses for a unit expressed in mills/kwhr
would decrease as a unit's installed cost in $/kw decreased, because it is probable that
a larger unit is being investigated.

      Operational costs  are primarily labor costs,  and regional variations in labor rates
are reflected in the  capital costs.  Therefore, regional-cost corrections are inherent in
the estimating method.   The cost estimates are below the national average of 0.75 mill/
kwhr since the newer plants need less maintenance because of advanced technology and
operational costs  are reduced because of large-scale operation.

Recommended Procedure

      It is  recommended that the operation and maintenance cost be estimated from the
correlating line on Figure 15.
                                  Transmission Costs
      The transmission line is used to transport the power from the generating station to
the distribution area.   In the context used in the model, the transmission plant denotes
the difference in equipment required by alternatives between the generating station and
the distribution area.  If, under two alternatives,  the generating station is within the dis-
tribution area for both, it is assumed that no differences in transmission plant need be
considered.  Transmission plants may be ac or dc,  and they may be overhead or under-
ground.  They are characterized by high capital costs and low operating costs, and their
voltage is usually at least double that of the distribution system.  Generally,  the  economic
size of the transmission line is one-third to one-forth the maximum technical capability
of the line.  Therefore, a line will take rather severe overloads under emergency condi-
tions.  Frequently, roughly parallel lines are installed to increase system reliability.
Direct-current transmission is in the experimental  stage and apparently will be preferred
only for transmitting very large blocks of power long distances, for use with underground
systems or for transmitting energy through large  bodies of water. Alternating-current
lines are normally used.  Underground transmission lines are used only in urban areas
and are 10 to  15 times  as expensive as overhead lines. Because of the higher voltages,

electromagnetic field characteristics,  and generally greater length of transmission lines,
both underground and overhead'facilities require reactors to compensate for the  reactive
impedance of the line and to prevent the energy from being dissipated before it reaches
its destination.               .    -        -         ......

      Table 4 presents the costs of overhead lines of various voltages.  However, note
that the power rating in the table is the technical rating and not the economic rating.
Figure  16 presents the cost of transformers for increasing the voltage from 220 kv to a
higher transmission voltage.   Table  5 presents the costs of compensating reactors for
the transmission lines.  All of these values have been taken from a Federal Power Com-
mission report. (''

losses are negligible at transmission voltages below 500 kv, and at 500 kv they are im-
portant only at times of precipitation when they may be as high as  100 kw/mile.  .Corona
losses have been discussed by Anderson et al. (10)

Discussion

      From the three-to-one variation in cost for a line presented in Table 4, it can be
seen that an accurate estimate of transmission-line costs cannot be  obtained without de-
tails of the line.  For the cost model it is suggested that an average cost be used where
specific data are not available.  The data plotted in Figure 17 indicate the  wide  variability
in capital cost.  It is also suggested that the line be designed for operation at about 30
percent of its thermal rating.  This is roughly in line with TVA voltage recommendations
for the various power capabilities.  Also, calculations using the costs presented later
indicate that this is approximately the economic loading.  These calculations also indi-
cated that the 30 percent figure was not  critical.

      The transformer  costs will be inherent in the system for voltages up to about
220 kv because the main distribution system will probably operate at that voltage.  There-
fore,  these  costs should be included in distribution costs, which are not part of this
study. Transformer  cost for stepup and stepdown over that voltage  should be added to
the transmission costs. Shunt impedances for compensation have not been considered.
They  will not be needed for transmission distances less than 200 miles.

      To assume reliable operations, it is  suggested that the same number of transmis-
sion lines be used as the generating plant has generators.  Usually a generator  is sized
so that its shutdown will not affect system reliability, and the transmission line should
be sized on  the same basis.  Underground lines are very  expensive  and will probably be
used only in the distribution system.  The costs are from 10 to 15 times the cost of an
overhead line.  If underground lines are needed, it is suggested that the minimum  figure
of 10  times  the cost of  overhead lines be used.

      The figure of 1  percent for maintenance cost in the  FPC  report''' appears reason-
able,  and it is suggested that this number be  used. This  includes the maintenance  of ac-
cess roads, weed control, and occasional storm losses.  The I^R losses can be calcu-
lated  easily after the wire size is estimated.  The wire sizes in Table 4 were used for
estimating this loss.  However,  the I R loss  varies with the loading of the line.  If the
loading schedule is not known, it is suggested that the line be considered as operating at
design load  or completely disconnected from  the station and load. Corona losses will

                                         45

depend upon the weather conditions.  For the curvei presented later, it is assumed that
the corona losses will average 20 kw/mile for a 500-kv line and  be negligible at lower
voltages.   Except at light loadings, this is not an important cost.  A loss  of 20 kw/mile
assumes that precipitation, dew, frost, fog, or other corona-causing weather conditions
will occur 20 percent of the time.
Recommended Procedure

      The following steps constitute the recommended procedure for determining the
costs associated with power transmission from generation locations outside the distribu-
tion network:

      (1)  Determine the capital cost of the  transmission line from Figure 18

      (2)  Determine the capital cost (if any) of transformerr from Figure 19

      (3)  Sum to determine capital cost

      (4)  Multiply the capital cost by 0.01 to determine annual maintenance cost

      (5)  Determine the electrical losses from Figure 20 and subtract this loss
          from the net power  generated by the generating plant.

                            Fuel Costs and Heating Value


      Data on fuel costs are usually available only in  some aggregated form as shown
in Table 6.  While this table is useful in identifying general regional trends, it over-
states the cost of alternatives available to utilities currently planning a new, large
facility. Average delivered coal prices are particularly misleading because they do not
adequately reflect the volume economies available to  a large purchaser who is located
near the mine mouth,  purchases from captive mines, or uses unit-train hauling.  These
differences are indicated by comparing  data from Table 6 with those in Table 7 which
shows typical fuel costs for utilities contacted during this program.  As an example,
while the average delivered coal price to all utilities  in the East South Central Census
Region in 1966 was 19. 3^/million Btu, the  delivered cost to three of TVA's larger sta-
tions in the same area ranged from 13. 7^/million Btu (in a mine-mouth location) to
17. 9^/million Btu.

      It would also be desirable to distinguish fuel costs at the source and the  transpor-
tation component from the delivered price.  An attempt was made to identify these com-
ponents during utility interviews, and where adequate data were  available,  the  cost of
coal at the source was estimated (Table 7). The deviation in  coal costs at  the mine  is
seen to be  much smaller for the three TVA stations mentioned before than  it was for the
delivered cost of fuel.  It has been found that for a given mode of transportation and dis-
tance, the  costs per ton mile are fairly uniform.  These transportation costs can be
applied to a particular evaluation considering  alternative  plant types  and sites where fuel
source and  source costs are known.  However, to develop a mass of data on estimated
fuel  cost at the mine  would require, as an  example,  the listing of a large number of
facilities and their as-burned fuel costs, determining the fuel-source location, and sub-
tracting an estimated transportation charge from this.

      At present, a reasonable  data base may be developed by assuming that each utility
performs a rigorous  analysis of alternatives in  selecting a plant site, and that their
choice represents the optimum costs  available to them at the  time, including both coal
costs as mined and transportation charges. Therefore,  as-burned fuel costs have been
tabulated from the FPC's publication  Steam Electric  Plant Construction Cost and Annual
Production Expenses^) for all generating stations 500 Mw(e)  and larger.  Volume trans-
portation methods are usually employed and should be reflected in the fuel  costs for
these larger stations.  These data have been plotted on United States maps and coal  costs
are presented in Figure 21,  oil costs in Figure  22, and gas costs in Figure 23.  Thus,
in any evaluation of a general nature which does  not require the isolation of the fuel
transportation component, the delivered costs of alternative fuels may be estimated by
referring to these three maps.

      The heating value of coal is seen to vary considerably among different regions.
Heating-value  data were  tabulated from the FPC's steam plant report'  ) and are pre-
sented in Figure 24.   The heat contents of  oil and natural gas are more consistent and
their average values  are also shown in  Figure 24.

      Unfortunately,  the  heating values for oil are shown in terms of Btu's/gal, while
to compute the sulfur content of oil used as fuel, a value in terms of Btu's/lb  is needed.
Values of typical heating values per pound  for residual fuel oils are given by the
American Petroleum Institute(^) as follows:

Another approach is to use the chart given by Perry*   to convert the values  shown on
Figure 24 (for oil) to Btu's/lb.  This results in the following:

                                              Oil Heating Value
                                             Btu/Gal     Btu/Lb

                     Rest of the Country     149,437      19,080

It is further observed that the API typical values  are not consistent with the Perry chart,
which indicates that actual values for each case of interest would  be desirable.  (Note
that a constant value of 18, 700 Btu/lb has been used in the examples shown in a later
section of this report. )

      One method of reducing sulfur oxide emissions, which is always available to utili-
ties, is to burn a fuel with a lower  sulfur content.  For many locations, however, this
alternative imposes substantial cost consequences. As an example, most of the United
States' reserves of low sulfur coal  are  located west of the Mississippi River'**',  whereas
a majority of the country's electrical generation facilities are located near more densely
populated urban centers east of the Mississippi.   For most of the eastern plants,  the
transportation cost for moving low- sulfur coal from western mines would be prohibitive.

      Some  reserves of low-sulfur  coal are located in the eastern coal fields.  Unfortu-
nately, the use of coal with more than 1 percent sulfur content has long imposed an un-
desirable cost consequence on the steel industry.  Because a majority of steel plants are
still located east of the Mississippi River, the steel industry has  taken prior claim on  a
major portion of the  eastern reserves of low- sulfur coal through long-term contracts.
Most plains states and west-coast utilities seem able  to obtain low-sulfur coal with little
cost penalty.

      East-coast utilities also face higher transportation charges for low-sulfur oil.
Most oil that is competitively priced for utility use on the east coast is shipped from
South America.  However, Venezuelan oil,  as an example, is typically high in sulfur
content.   The lowest cost low sulfur oil in many cases is shipped from Africa, and this re
suits in a higher delivered cost. On the west coast, oil with  2 percent sulfur or less is
available at competitive prices from domestic sources.

      An example of these  cost consequences is offered by the experience of Consolidated
Edison, the electric utility  serving New York City, which  recently reduced the allowable
sulfur content of their  fuel purchases from 2. 5 percent to  1 percent or less.   Changes  in
volume fuel costs as a result of the new sulfur specifications are  summarized in Table 8.
•This can be achieved not only by using natural fuels which are low in sulfur but also by modifying the fuel. For example,
 currently there are efforts by the National Air Pollution Control Administration to develop and demonstrate improved
 conventional coal-cleaning practices for reducing sulfur contents.

      Table 10 presents the heat rates for generating units over 300 Mw and for  stations
where the average size of unit is over 300 Mw.  This table is slightly biased toward the
better heat rates because poor unit heat rates are not available for individual units.
However, it does not appear that many poor heat rates were missed.

      The heat rates in Table  10 were obtained from the 1965 and 1966  editions of
Steam-Electric Plant Construction Cost and Annual  Production Expenses,  published by
the FPC. (3)

      The heat rate of an individual plant  tends to increase with time because of  an
increased number of stops and starts and because of poorer  operating conditions.  There
fore the very good heat rates for the newer plants probably will not be  maintained.  The
Eddystone plant has a heat rate  about 400 Btu/kwhr  less than its contemporaries.  How-
ever, the Eddystone plant was twice as expensive as other plants of similar size.

      The heat rate also  depends upon the type of fuel.  When calculating the heating
value of the fuel it is assumed that the water in the fuel, and the water formed by the
combustion of hydrogen,  will be condensed, a condition obviously not obtained in a
boiler.  About 4 percent of the heating value  of coal, 7 percent of the heating value of
oil, or 10 percent of the  heating value of gas is not available because of the water vapor
in the flue gas.  The heat rates  when burning oil and gas therefore are consistently less
than the heat rates when burning coal.

      Twenty-one units of all sizes had heat  rates under 9000 Btu/kwhr.  These  are all
fairly new plants and their heat  rates are expected to become poorer as they become
older.  The best heat rate obtained with any  plant is 8,667,  only 4 percent less than
9, 000 Btu/kwhr.   With the present high money rates, and with nuclear plants taking
over in high-fuel-cost areas,  it appears that the capital costs rather than fuel costs
will be reduced in the near future. Therefore,  a rapid decrease in the heat rates of
new plants is not expected. A 9, 000  Btu/kwhr rate  for new  coal facilities is thus re-
commended.  Gas and oil plants will  probably be of similar  design, and correcting for
the lower net heating value of the  fuel,  the rates will be 9, 350 and 9, 700 Btu/kwhr for
oil and gas.

      The heat rate probably can be estimated more closely than any other cost  factor
in the model.  The differences in  heat rates  between the best and poorest coal plants
are about 10 percent.  The differences in size,  age, and other factors appear small
compared with expected  variations in other parts of the model. However, it is recom-
mended that a different heat rate be used for the different fuels because of well-
established differences.   These differences may be  important if incremental costs
between  fuels are compared, even though the total cost change maybe insignificant.


Recommended Values

      It is recommended that the heat rate for coal-fired plants be estimated at  9, 000
Btu/kwhr,  oil-fired plants at  9350 Btu/kwhr, and gas-fired  plants at 9, 700 Btu/kwhr.

                              Station Capacity Factor


      If cost comparisons are to be made between generating facilities on the basis of
some cost per kwhr,  then the selection of the appropriate plant capacity factor is crucial
since it determines by how many units the  capital costs and carrying charges are to be
divided.   Capacity factor is defined as follows:


          _     •«.,._     Kwhr generated in a given time period	
           apaci y  ac or - Name plate kw rating X hours in the time period

      The usual operating procedure for  a  utility on any given day is to increase the
portion of the load being carried by those generating facilities  with  the lowest incremen-
tal fuel cost first.  As these efficient units are loaded to capacity,  less efficient units
with higher unit fuel costs are started next. The reverse procedure is followed as  sys-
tem  load declines. Because the newer power plants are usually the most efficient, and
therefore have the lowest incremental fuel costs,  these  are the units that are started
first and shut down last.  They are the generating units  with the highest capacity factor.
One  limit on any unit's capacity factor is its expected outage rate.   Thus, the typical
history of a generating unit is that its capacity factor may be modest (50 to 70 percent)
in the first year or two of operation until the many operating and equipment difficulties
have been resolved.  Over  the next 5 years, it will probably remain among the most
efficient plants in the  system,  and its capacity factor should range between 70 and  85
percent unless unusual maintenance is required.  More  efficient plants should be avail-
able and operating in the  remainder of a  ZO-year period, and the capacity factor should
gradually decline to within  the 40 to 60 percent range.  Finally, in the later stages of its
useful life,  the unit will be relegated more and more to  peaking duty,  and its capacity
factor will further decline to the 20 to 40 percent  range.  Unless the unit is unusually
efficient for its time,  the average capacity factor for a unit over its life  should not differ
substantially from the average  system capacity factor.

      Table 11 lists the average capacity factor for each United States' census  region and
the United States' average.  There are only minor deviations from the nation's  average in
individual census regions with the exception that the capacity factors are higher in indus-
trialized urban regions and are lower in the rural areas.  Individual-utility average ca-
pacity factors deviate more widely.  As  an example, Ohio Power Company, located in
the East North Central Region has a capacity factor approaching 70 percent. Nevertheless,
for fossil-fuel-fired steam plants,  the average data in Table 11 should provide satisfactory
accuracy for use in the model.

      Adequate operating experience has not been acquired for nuclear facilities to make
their historic capacity factors meaningful.  Many utilities are estimating 75 to 85 percent
capacity factors  for nuclear facilities when making the investment decision.  This  figure
which is higher than system average, is  justified  on the basis  that although the anticipated
average  cost of electricity  generated by  a  nuclear station will  be close to that of a  fossil-
fired unit, the incremental fuel cost is much lower.  As discussed in the  section on
Nuclear  Generation,  carrying charges comprise a significant portion of the cost of nuclear
generation.  Thus, the utilities reason that the first nuclear facility they install will have
a capacity factor higher than system average.  However, as more and more nuclear plants
are  added to any one system, their individual capacity factors must drop and approach the
system averages.  This tendency is estimated in Table  12 which is  a projection of  United

States' average capacity factor* for various forma of generation.  It shows estimated
average capacity factors  for nuclear facilities of 80 percent in 1975 but of only 70 per-
cent by 1985.  Finally, it must be noted that as the installation of more and more nuclear
facilities with capacity factors, higher than the system average are projected for  the
future, the capacity factors of the remaining fossil-fired stations must fall below the
system averages.


Recommended Values

      It is  recommended that the average station capacity factors of Table 11 be  used
whenever better, more specific information is not available.


                           Sulfur Dioxide-Control Devices
      The cost of a sulfur-control device to the electric consumer depends upon the
direct cost of the device and upon the extra cost incurred from losses in transmission
because of the more  expensive power.  However, the latter cost is small and conse-
quently the major cost to the consumer is for the operation of the sulfur-control device.
Therefore,  the assignment of an arbitrary cost to the sulfur-control device is almost
identical to the assignment of an arbitrary incremental cost to the consumer.

      How the  data available at one operating condition  were extrapolated to other
operating conditions  is described below.   The Katell studies for 800 Mw plants using
the alkalized-alumina and the catalytic-oxidation processes have been used for the cost
base.
Data

Mw(e) plants burning coal with a 3 percent sulfur content and operating at a 90 percent
load factor.  Recently Katell^?) has modified one component of the annual cost,  the
payroll overhead, by increasing it to 25 percent of payroll.

      Other data are being developed for the National Air Pollution Control Administra-
tion by other contractors but are not yet available. Chilton^) has presented many
methods of extrapolating costs from one level of operation to another.  Basically the 0.6
power rule, with modifications,  is recommended.
      Other cost data have been presented by Johswich^^J^  Katell and
Bienstock, Field, Katell, and Plants <2°),  Field, Brunn, Haynes, and Benson(21), and
Kiyoura'22', and in an article in Sulphur(23).  The data of Katell^)  were U8ed because
they were the most detailed.

      When using the model, costs for many plant sizes and operating conditions are
necessary.  Therefore the assumptions below were Used to extrapolate Katell1 s data
other plant sizes and operating conditions.

      (1)  Capital costs are an 0. 6 power function of size.

      (2)  Catalyst and absorbent costs are proportional to size.

      (3)  The size of the absorbing section of the sulfur control device is
          proportional to the negative logarithm of the fraction of sulfur
          not removed from the  stack gas.

      (4)  The size of the desorption and sulfur -processing  section of the
          device is proportional to the sulfur recovered.

      (5)  Manpower  requirements are constant.

      (6)  Some operating and maintenance costs are proportional to the
          capital cost.

      (7)  Other operating expenses are proportional to the  power generated.

      (8)  Still other  expenses are proportional to the amount of sulfur
          recovered.

      (9)  Payroll overhead is 25 percent.

      From these assumptions,  the equations below were developed for capital and
operating costs. The procedure followed was to express each of the above nine cost
components as a function of plant size, etc., using the  data of Table 13.   The co-
efficients of like terms were then  aggregated to obtain the capital-cost equation:

                  S = sulfur content of coal, percent

                SC>2 = allowable SO2 emission, ppm.

      Similarly, the ope rating -cost equation can be expressed as:

Cost = AI x labor  rate

          x capital cost
     + A3 x MW x LF     '

     + A4x MW x LF x log1Q [ 667S ]


     +. MW x LF x (667S - SO2) x (A5 + AS€ x price coal - AsS x price sulfur),

where A\, A2, etc. , AgC and AgS are aggregated coefficients and LF is the load factor.

      At present this cost has been calculated as a recurring cost not including financial
factors.  However,  the financial factors,  amortization,  insurance, profit,  interest,  etc.,
could easily be included by adding  the appropriate amount to A2.  In the procedure devel-
oped and presented  in this report,  however,  an alternative method has  been used.  The
procedure developed is discussed in another section.

      For an individual process, several of the aggregated coefficients have been found
to be zero.   Table 14 lists values of the coefficients for two  803- control devices.  The
constants for other  control devices could be determined from one detailed cost
breakdown.

      The method of cost estimating is as accurate as the present cost  estimates.  Within
one process, the estimates indicate  with reasonable accuracy how costs change with
changes in the various independent variables.  When comparing different processes, the
cost data probably are not sufficiently reliable and should not be used to determine the
lowest  cost alternative.   As more  accurate cost data become available,  the coefficients
in the equations can easily be reevaluated.

      The pattern of costs for the alkalized-alumina and catalytic-oxidation processes
are different.  The catalytic-oxidation process should be more advantageous  than the
alkalized-alumina for the largest plants operating at the highest load factors, with the
maximum sulfur removal, and with the highest-sulfur coals.


Recommended Procedure

      If data are available for the specific operating conditions, it is recommended that
these data be used.  If they are not available,  it is recommended that cost be determined
from Figues 26 through 29, which are  graphical solutions for the equations discussed
above but do not include  a sulfur credit.  If the operating conditions are such that the
costs cannot be read from the figures, then the equations should be used with the aggre-
gated coefficients given in Table 14.
                               Sulfur Content of Fuels


      With the advent of SO2~ pollution controls,  a premium is being placed on low-
sulfur fuels, and high-sulfur fuels may sell at a discount.  At present, sulfur-control
regulation is just starting to affect the prices, and the final price structure can only be
estimated.  Presumably, low-sulfur coal eventually will sell at a premium equivalent

 to the cost of removing sulfur dioxide from the flue gas by the least expensive method.
 At present, low-sulfur oil in New York sells  for 37^/MM Btu, while high-sulfur oil
 sells for 28^/MM Btu.  In general, premiums are not charged for low-sulfur coal, ex-
 cept that often the low-sulfur coal mine is farther from the electric plant than is the
 mine for high-sulfur coal and there is  a transportation price differential.
 Data

       Figure 30^4) shows that in 1964, electric utilities  consumed less low-sulfur coal
 and more medium-sulfur coal than the national averages.  Table 15 pinpoints coal ship-
 ments to utilities in the year  1964 from specific coal-producing regions. (24)  Not only
 is the tonnage  shipped from each producing region to electric utilities presented,  but
 also the range and average sulfur content of those shipments.   Figure 31 (25) js a map
 which identifies the various coal-producing regions.  As  indicated in Table  15, the
 weighted average of sulfur content for coal burned by electric utilities is 2.3 percent.
 This is for cleaned coal; for coal not cleaned as is used by some utilities, the sulfur
 content would be 0.3 to 0.5 percent higher.

       Figure 32 shows the oil-using  regions and Table 16 shows typical sulfur contents
 (minimum, average,  and maximum) of oils used in these various regions. "6)  Trend
 data indicate that the  national arithmetic average sulfur content of 129 samples of fuel
 oil burned by electric utilities was relatively constant around 1.6 percent in the 5-year
 period I960 through 1965.

 Discussion
       The option of burning low-sulfur coal is available only to a few utilities  and not to
 the industry at large because insufficient low-sulfur coal is available.  Only about 40
 percent of the bituminous coal mined has a sulfur content of less than 1 percent and most
 of that is used in the manufacture of steel.

       A comparison of the coal reserves with the coal production listed by DeCarlo,
 et al. (24) indicates that the sulfur content of  coal will increase as the low-sulfur reserves

are depleted.   The steel industry,  the second largest user of coal, would be more seri-
ously affected by an increase in the sulfur content of coal than the electric  utilities and
therefore should be willing to pay a higher premium for low-sulfur coal.  Thus, the
option of reducing sulfur emmission by  the substitution of low-sulfur coal,  o.r the equiv-
alent by deep cleaning or conversion to  gas or liquid fuelj for high-sulfur coal will be
available only in special cases.

      The simplest way to treat the additional cost of low-sulfur coal is to compare the
distances from the mines to the generating station  and assume that all of the cost dif-
ferences is  due to additional transportation costs.  Current data do not permit deter-
mining the price differential between coals of different sulfur  contents.
Recommended Values

      It is  recognized that the best information for use in the model for evaluating
specific situations might be obtained directly from the electric utility or coal supplier.
In a comparison being made between a high-sulfur coal and a low-sulfur coal, quotations
for both fuels, if possible on a delivered basis,  would be most desirable.  However, in
most evaluations and, in particular if a hypothetical plant is being considered, the sulfur
content of the coal should be taken from Table 15  for the region of use and origination.

      The only present basis  for comparing the prices of low- and high-sulfur oil is the
experience in New York of Consolidated Edision.   Therefore,  the cost of a low-sulfur
oil should be estimated as being 20 percent higher than the applicable high-sulfur-oil
cost.
                                    Sulfur Credits
      The prospect that substantial quantities of sulfur could be recovered from the stack
gases of electric generating facilities poses  the problem of determining a probable value
for the  sulfur.  In  the context of this program,  the value figure needed corresponds to
the so-called "net  back" that the producer of sulfur realizes from sales at his producing
location.

      The value of sulfur to the consumer depends on his use of it and the relationship
that this bears to the commercial forms of sulfur available to him.  The consumer of
sulfur who is making sulfuric acid can utilize a wide variety of forms  - brimstone
(elemental sulfur), pyrites, sulfur  dioxide from smelter gas,  hydrogen sulfide,  certain
petroleum sludge acids, etc.  Conversely, the consumer of sulfur who is making matches
or compounding rubber products has to have brimstone in solid form with specific physi-
cal properties and purity requirements.  In  effect,  the markets for sulfur in  the United
States require the  producers to supply a multitude of forms and quality levels,  each
tailored for  its intended end use.

      The principal forms  in which sulfur is consumed include (1) crude brimstone, either
dark or bright, (2) processed sulfur or refined sulfur,  and (3) sulfur dioxide  derived from
roasting of pyrites or nonferrous sulfides.   Crude brimstone contains a minimum of 99.5
percent sulfur, and when contaminated with  carbon from Frasch-mined deposits, it is

known as  "dark" crude brimstone, entirely suitable for making sulfuric acid but not
acceptable for many other uses.  A minor quantity of Frasch-mined brimstone and vir-
tually all  the recovered sulfur produced from some natural gas or petroleum refinery
off-gas streams is bright crude brimstone,  suitable for conversion to processed  sulfur
or for many nonacid uses.  Processed sulfur contains from 93 to 99.9 percent of sulfur,
has the characteristic yellow coloration, and is treated to make it  suitable for a specific
nonacid use,  such as rubber compounding,  pesticide formulation, or match manufacture.
Sulfur dioxide,  a gas at ambient temperatures and pressures,  is used predominantly for
making sulfuric acid in a plant adjacent to the sources of the sulfur dioxide.


Sulfur Consumption

      In 1966, the latest year for which "official" data are available, apparent consump-
tion in the United States amounted to about 9.2  million long tons'^') Of sulfur equivalent
in all forms.  This was supplied from domestic production of brimstone, pyrites, and
sulfur dioxide in smelter gases and imports of brimstone and pyrites,  as shown in
Table  17.

      These are the only so-called "official" data known to exist with respect  to the con-
sumption  of all forms  of sulfur in the United States.  It will be noted that the emphasis
for these  data is the source of the sulfur and not the use to which it is put or the  inter-
mediate products by which this supply is converted to end uses.

      "Unofficial" estimates prepared by representatives of the major U.  S. Frasch sul-
fur producers(28) indicate that 82 to 87 percent of the sulfur consumed in the United
States is used to make sulfuric acid.  The balance of 13 to 18 percent is consumed in a
large number of end uses and industries, among which the pulp and paper,  industrial
chemicals, rubber, and pesticides industries are relatively important. Table 18 presents
Gittinger's estimates. (28)


Sulfuric Acid Markets

      Neither of the sources of da.ta.^> ^°' attempt to detail the geographic distribution
of sulfur  consumption in the United States.  However, data on the production of sulfuric
acid is collected and reported by  the U.  S. Bureau of the Census on a regional basis;
from this sulfur consumption can be approximated by applying an appropriate  conversion
factor. In prior studies, Battelle has developed such a conversion factor that agrees
rather well with the "unofficial" estimates for  consumption of sulfur in sulfuric acid.  To
produce 1 short ton of sulfuric acid (100 percent basis) requires approximately 0. 3 long
tons of brimstone in a modern catalytic acid plant.  Although a number of less efficient
chamber  acid plants are  still in use,  the application  of the 0. 3 factor to total  new acid
produced is an adequate first approximation of regional sulfur consumption for sulfuric
acid.  Table 19 presents Bureau  of the Census data for production of new sulfuric acid
in selected geographic areas.   To avoid revelation of specific plant data,  the  distribution
by area differs  from the  usual presentation of the nine standard Census regions.

      It will be  noted  that the several sets  of data do not  result in a statistically  compat-
ible series of numbers for any given year.  This  results  from differences  in orientation
of the various reporting agencies and their  inclusion or exclusion of certain data, for
example, the spent acid burned in a number of acid plants located beside petroleum

refineries.  This spent acid is included in the Census data but is not recorded elsewhere
as a source of sulfur except as a rather gross estimate prepared by "unofficial" sources.

      As shown in Table 19,  the Middle Atlantic and North Central areas - containing a
large share of the industrial production of the country - has had a  rather modest growth
from I960 to 1966.  The major increase has occurred in the Southern area - especially
Florida and Tesas - under the impetus of rapidly expanding markets for phosphatic
fertilizers.

      For the near-term future - say 1975 - the industrialized northeast is expected to
continue the growth pattern of the past few years.  On the other hand, the rapid growth
of phosphatic fertilizers will be moderated by capacity in excess of demand until  the
latter part of the period.


Regional Value of Sulfur

      Traditionally,  Frasch brimstone produced in the Gulf Coast  area  has been the
price leader for sulfur both within the United States and worldwide.  Since 1965,  the
quoted price for brimstone fob Gulf ports has risen from $26. 50/long ton for dark crude
to the current level of $41.50.  To a large extent, the fertilizer buildup in the United
States has accounted for a demand in excess of productive capacity for sulfur.  Between
1963 and 1967,  the production deficit was  supplied from producers' stocks,  but the pro-
longed shortfall permitted producers to raise prices without fear of substitution.

      Production increases effected in 1966 and 1967, coupled with 2 years of less-than-
expected growth in phosphatic fertilizers - also 1966 and 1967 - combined to reestablish
the  supply-demand balance late in 1967, and the preliminary indication  is that some
addition will be made to producers' stocks during 1968. Assuming that the producers -
worldwide  - will be  able to meet near-term demands,  it is  anticipated that the fob Gulf
ports quoted price for brimstone will fall  to the $30 to $35  range by about 1970 and re-
main in that range through 1975.

      On the basis of the current quoted price - $41. 50 fob Gulf ports - brimstone has
an approximate value of $48.50 in the New York - New Jersey area, and $50 to $52 in
the Chicago or Pittsburgh areas on the basis of ship  or barge transportation in molten
form.  These are the approximate values  for sulfur with which sulfur recovered  from
power plant stacks would compete. By 1970, the  comparable values are expected to be
$37 to $42  in New York - New Jersey, and $40  to $43 in Chicago and Pittsburgh,  assum-
ing that the bulk of the  demand will be supplied  by shipments from the Gulf Coast.  When
more than one-third of the local (within a 100-mile radius) demand is available from
local sources at prices equivalent to or less than the prevailing Gulf ports price,  the
local market price will be depressed.  Further, if the local area becomes an export
center - i.e.,  produces more than the local demand - the  adjacent areas also will ex-
perience price depression toward the prevaling Gulf ports price, under the assumption
that the local production is in the form of brimstone  with quality equivalent to crude
Frasch brimstone.

      A study of local demand centers in the northeastern part of the United States appears
to be necessary to properly assess the impact of any given sulfur-recovery installation
from generating-facilities' stack  gases.

Recommended Values for Recovered Sulfur

      The electric utility recovering sulfur from stack gases will be faced with the
problem of disposing of that sulfur and concurrently with the problem of setting a price
for it.  As indicated in the preceding section, the site of recovery and the sulfur supply/
demand relationship in that area will influence the "net back" that the utility could ex-
pect.  But the costs for selling that sulfur represent expenses that must be deducted
from the "net back" to determine the value the utility can credit to the producing
installation.

      Two principal routes  are open to the utility recovering sulfur with respect to dis-
posing of it.   Firstly, the utility may decide  to handle the marketing of the sulfur on its
own and become a competitor for any markets available. Secondly,  the utility may elect
to arrange for the marketing of the sulfur through an established organization, thus avoid-
ing an entry into the chemical  business.  The choice between these two alternatives will
depend on a number of factors, including the important consideration of the quantity of
sulfur involved and the status of the sulfur market in the area.

      For preliminary planning purposes, either alternative mentioned above  will in-
volve expenses over and above the cost of actually producing the sulfur.  These expenses
should be deducted from the sales price received in order to determine the  credit to the
producing facility.   When the utility becomes the marketing agent, it can be anticipated
that about 20 percent of the sales price will be allocated to selling expenses,  general
administrative overhead, and profit.  Thus,  at a sales price of $37/long ton,  the credit
to the producing facility would be $29. 60.  If the utility  can arrange for sales  to be
handled by an outside organization, the sales commission might be negotiated to be about
10 percent of the sales price,  which would yield a credit to the producing facility of
$33. 30 on a sales price of $37/long ton.

      Between these two alternatives, the latter appears to be the more attractive choice
to maximize the value credited to the producing facility.  However,  it can be  anticipated
that the established sulfur-marketing organizations might resist such an arrangement,
forcing the utility to undertake an independent marketing effort.  In the initial operation
of the model it is recommended that the assumption be made that the utility will have  to
handle the marketing of the sulfur and will incur the associated expenses, leaving 80
percent of the sales price as the credit to the producing facility.

       Further,  the assumption should be made that the effective  sales price for sulfur
in the period from 1970 to  1975 will be about $30/long ton fob U. S. Gulf ports.  This
will mean an effective sales price of $37/long ton in the New York area,  and  $40/long
ton in the Chicago or Pittsburgh areas under current  supply conditions.

       If the recovery process  results in the  production  of sulfuric acid instead of brim-
stone,  the calculation of its value becomes more complex.  With sulfur selling for about
$48/long ton in New York currently,  the quoted price for 100 percent sulfuric acid is
$34. 65/short ton fob works. One short ton of this acid will contain 0. 3 long tons  of sul-
fur having a value of $14.40, the balance being attributable to conversion costs,  sales
and administrative overhead expenses, and profit.  For simplicity, call this  figure $20/
short ton.  Then, with sulfur selling at $37/long ton,  the resulting sulfuric acid should
sell for $31. 10/short ton in the 100 percent  grade.  This figure would then be reduced
by 20 percent to arrive at a credit of $24. 90/short ton of acid to the producing facility.

      In the event that the recovery process yields a lower strength and contaminated
acid,  it would be necessary in most locations to process it to a clean 100 percent acid
to assure markets for it.  On the  basis of estimates of concentration and filtration costs,
Battelle calculates that a 70 percent acid would have to  sell for $5 to $6/short ton less
than the going market price for 100 percent acid in order to be marketable.  Again assum-
ing the $37/long ton sulfur price,  the  sales price for the 70 percent acid would be $25. 10
to $26. 10/short ton fob works, with a probable deduction of 20 percent from this as the
value credited to the producing facility,  say $20. 10 to $20.90,

      By means of these relationships, values for recovered products can be calculated
for any sulfur price  between $30 and $45/long fob Gulf ports.  Below $30 and above $45,
recalculation of the appropriate prices for 100 percent and 70 percent sulfuric acids
would be necessary.


                         Carrying Charges	Treatment of
                     Financial Costs, Depreciation, and Taxes


      Although carrying charges quoted  by individual utilities are seen to vary consider-
ably because of the items included, at some point in their investment decision each com-
pany must consider similar factors.  As an example, some companies choose to include
a component for "general supervision and maintenance" in their carrying charges.  In
Battelle's model,  all such costs are considered under regular recurring costs (as are
property taxes and insurance).  Thus, the only elements remaining for separate inclusion
as carrying charges are financial costs,  depreciation, and gross-receipts and income-
based taxes.  Because utility returns  are predictable,  most taxes can be expressed as a
percentage of this return,  and it is common utility practice to include taxes in their
carrying charges.

      The effective property-tax rates that are included under recurring costs are de-
rived from Netzer's study/^O) and represent the average of the effective rates applied
to all taxable property in a state in I960.  These state averages were in turn combined
to derive  averages for each FPC  District (Table 20). Actual taxes on individual power
plants  within a single FPC district will vary widely from these averages depending upon
location,  because the administration of property taxes is highly fragmented.   The  fact
that I960  statistics are being used should not introduce too much bias in estimating cur-
rent tax levels as applied to power-generating stations since many of these are located
outside of metropolitan areas.  Rural areas traditionally have lower property tax rates
than metropolitan regions.

      The financial components of the carrying charges are subject to less regional
variation  for two reasons: (1) electric utility return is regulated by individual states
whose  regulatory philosophies are fairly similar and (2) utilities compete in a national
market for capital.  Since the deviation in financial  risk between various utilities is
relatively small,  so is their interest cost for debt securities  at any given time.

      Considerable discussion surrounds the selection of appropriate  "cost of capital"
or "target return" rates to be used in evaluating investment alternatives.  One point
frequently raised  is  that these costs should represent conditions anticipated during the
life of the project and not historic costs.  Fortunately,  for purpose of this study, the
utility return on investment (the combined return on bonds and the  equity of all classes

of stock) is  regulated by the individual states.  Not only are these procedures somewhat
similar among states, but,  in many cases, legal proceedings are required to alter the
allowable return.  The latter procedure tends to make changes in rates and utility re-
turns far less volatile than  swings in the financial markets.

      The Federal Power Commission provides a  tabulation of rates of return for all
electric utilities, calculated on a consistent basis, in its annual statistical summary.^ D
It must be emphasized that  this "rate  of return" is different in a financial sense than the
one usually  considered because it includes the return on debt as well as equity compo-
nents. Figure   shows the median United States  return from 1961 through  1966.  In
1966, 75.9 percent of all U. S.  electric utilities earned returns of between 6.00 percent
and 8.99 percent; thus, the disperison around the  7.44 percent median is fairly small.
Although this  rate of return has been steadily rising for the past 5 years,  the rate of
increase appears to be leveling off.

      The computational procedure outlined in the FPC summary(3D was applied to  the
composite income statement and balance sheet of all United States electric utilities for
1966 which are summarized in the same publication.  These calculations produced an
average return of 7.03 percent.  The fact that the  average  return is 0.945 times the
median indicates a  skewed  distribution of returns,  and we  have assumed the distribution
to retain the same shape  every year.   Thus,  in any year, the average return should
approximate 0.945  times the median return published by the FPC. This estimation  is
applied to historical data in Figure 33.

      Sample  calculations are  summarized in Table 21.  These are based upon both the
current average 7.0 percent return figure and a 7. 5 percent return in order to reflect
anticipated future conditions.  The average interest rate paid by all electric utilities on
their debt is included in this return and can be calculated from the summarized financial
statements in the FPC statistical summary.   This rate was 3.67 percent in  1966. Should
the utilities continue to pay 6 percent or more for new long-term-debt securities, this
average interest cost should rise substantially. The 7.5 percent return figure assumes
an average interest cost approaching 5 percent; however, the earnings rate  on  equity is
assumed to  have remained  the same  in this calculation.  In the long run, the equity  re-
turn rate would also rise in order to maintain a spread representative of the different
risks inherent between these two types of securities.  For purposes of reviewing the
appropriateness of the return component of the carrying charges  calculated  in this re-
port, however,  one need only check the trend of median utility returns published in
future FPC  statistical summaries, apply  the appropriate average to median ratio
(0.945),  and consider current  trends in the financial markets.

      Because interest expenses are deductible from State and Federal income taxes it
is necessary to know how the total return is divided between return on debt and equity.
Actually,  the  FPC  calculated return includes  a third relatively small  factor, tax credits.
The distribution for a 7.0 percent return  is estimated from the composite financial  state-
ments in the FPC statistical summary(31) and is shown in Table 22.   The estimated dis-
tribution for a 7. 5 percent  return (assuming the added 0.5 percent is  entirely attributable
to higher interest costs) is also  indicated.

      Other assumptions made in generating the carrying charges were the use of sinking
fund depreciation for making the investment decision and double-declining balance depre-
ciation for tax purposes.  The sinking-fund discount rate was assumed to be the same as
the cost of money.   A United States' utility average debt-equity ratio in 1966 of 0. 5226  to

            (a) Assumes that all of increased return is attributed to increased interest rates,
0.4774, calculated from the FPC statistical summary,     was used.   Furthermore,
interest costs on long-term debt were based upon the 1966, 3. 67 percent utility average.
Federal income tax calculations included the 10 percent surcharge, and a 52. 8 percent
effective rate was employed.

      State income tax rates and gross receipts rates vary widely; indeed, some  states
have no form of corporate income tax or special  revenue taxes  on utilities.  Effective
rates for the year 1966 were obtained from The State Tax Handbook 32) and are tabulated
in Table 23.  These rates,  in turn,  were averaged for the group of states in each FPC
district, and the average rate for each district is also shown in Table 23.  In certain
states,  Federal Income Tax is deductible from the state tax.  In these  cases,  the pub-
lished state rate has  been reduced by a factor representing the  deduction, so that the
percentage shown is the effective rate on net income before income taxes.  In other
states a tax is  imposed on each kwhr of electricity generated.  On the basis of United
States'  averages,  this generation tax has been converted to a fraction of gross  receipts
and is included in the gross receipts tax rate in Table 23.

      Carrying charges computed on the basis of these  assumptions and stated as a
constant annual percentage of the original investment cost are summarized in Table 21.
These carrying charges have been calculated both for a 7.0 and 7. 5 percent return and
consider a 20- and 30 -year planning period.  Data derived from the FPC statistical
summary and all other historic cost data would currently reflect carrying charges  at
7.0 percent and 30 years.  Utility rates are normally based upon historical costs; thus,
this  combination of return and equipment life might represent the impact of an invest-
ment decision on the  cost of electricity as  generated.

      For the purposes of planning, however,  the utility may wish to minimize the  risks
attributable to uncertainty and would evaluate the investment over  a shorter,  20 -year
period.   Furthermore, it might apply an anticipated return rather than historic figure.
Thus, for the purpose of simulating a utility investment decision,  carrying charges based
upon a 20 -year life and 7.5 percent  return  might  be more realistic.

      For a given rate of return and planning period, it has been assumed that these two
factors  will not vary among the eight FPC  Districts.  Thus,  although state income  taxes
and gross revenue taxes do vary from one  location to another, these are all deductions
before net income.  Net income is assumed constant; therefore, the Federal Income Tax
charge  will not show a regional variation.

      The relative sensitivity of these carrying charges is illustrated by the four cases
in Table 21.  For a given evaluation period, there is little variation in the overall carry-
ing charge as a result of changing costs of money, if the change is primarily in the inter-
est cost on debt. In the long run, one would expect the return on equity to rise also and
this would ultimately result in substantially increased carrying charges since all the tax
components would then also increase.  Although not  shown, one could anticipate a high
degree  of sensitivity to a change in  income tax rate if a given return after taxes is to be
maintained.  Finally,  the anticipated sensitivity to changes in depreciation or planning
period is shown by comparing  the examples for 20 to 30 years for a given rate of return.

      It should be pointed out that in the cost model and in the treatment of annual carry-
ing charges,  the investment,  operating costs,  etc.,  of the 803-control process have been
considered in the same light as any other component of the power station.  Under current
laws and regulations,  there appears to be some question as to the validity of this
approach.  It is not appropriate to argue this point here.   But, if some other method of
treatment proves to be necessary, only minor modifications of the model structure will
be needed.
                                   Insurance Costs
      Insurance costs for generating facilities consist primarily of two components,
property and liability insurance.  The cost is divided nearly equally between these two
types and the total cost varies in proportion to the size and value of a facility.  The  cost,
therefore, may be stated as a percentage of plant first cost, and this percentage  will be
nearly uniform for all sizes of conventional steam plants.

      An early impediment to commercial development of nuclear power was the  question
of unlimited liability in the event of an accident.  Although the probability of such a
catastrophe is minute,  without some actuarial experience,  insurance companies were
unwilling  to provide insurance,  and without some legal limitation on their liability, po-
tential users were unwilling to risk developmental investment.   The Price-Anderson
Act of 1957 provided this statutory limitation, and it further authorized the AEC to
indemnify parties held liable for damages incurred as a result of a nuclear incident.
AEC coverage is extended only for amounts  in excess  of $74 million and up to the statu-
tory limit.  This, in effect,  limits the amount of privately placed liability-insurance
coverage  required for a given nuclear facility to $74 million and tends to lower the cost
of insurance coverage, stated as a percent of first  cost, as the size of nuclear plants
increases.  Nevertheless, insurance costs are considerably higher on a nuclear plant
than on a  comparable sized fossil-fuel-fired  installation because of the greater potential
liability and the larger investment required per Mw(e) of capacity.

      Annual insurance costs expressed as a percentage of unit first cost were computed
from a number of sources and plotted in Figure 34.   These sources include  data acquired
from field interviews, the National Power Survey, *-*3) an(j an analysis done  by S. M.
Stoller Associates,  a nuclear consultant,  for an A. D. Little report on the "Future
Market for Utility Coal in New England". (34)  Trend lines  have been estimated and are
suitable for use in the model; however,  it would be desirable to  develop a larger  data
base, in particular,  to more accurately estimate nuclear insurance costs.

                           NUCLEAR-POWER GENERATION
      Nearly half of all the new electrical-generation capacity planned between now and
1974 will use a nuclear energy source.  Although a variety of subjective considerations
(such as possible future pollution-control regulations) may have had an impact upon these
decisions, the primary determinant was undoubtedly anticipated economic gain.  Although
some question is still  raised about future supplies of fissionable material, the overriding
cost component in any nuclear-power-plant evaluation is the capital cost of the facility.
On an annual basis, carrying charges are typically one-half  of the total cost of nuclear
power generation.

      Unfortunately, these investment costs have fluctuated widely and have  trended
sharply upward in the  recent past.  Since there is a long lead time (at least 6 years)
between announced construction and the in-service date of a  nuclear plant, these higher
costs will be reflected in stations coming on line after 1974.

      For the purpose of this study, nuclear generation may be considered as an alterna-
tive to controlling the  SO2 emissions from a fossil-fuel-fired station.  Therefore, pri-
mary interest  is in the anticipated costs of nuclear plants being planned at any given point
in time.  With the nuclear cost picture being so  volatile, historic  cost data are not very
useful for this purpose.  Furthermore, only a small number of nuclear stations are cur-
rently in operation, and historic nuclear cost data are not available in abundance.   Cost
data for nuclear facilities  are tabulated in the FPC's publication Steam-Electric Plant
Construction Cost and Annual Production Expenses(^); however, the facilities included
to date are  smaller than 300 Mw, and it will be several years  before enough larger
nuclear plants are in operation to make this a useful data source.

      Table 24 is a listing of costs made available by utilities visited in the course of
this study.  The data are useful as indications of relative costs; however, the data base
is too small to allow meaningful aggregation.  Table 25 is a tabulation of nuclear plants
for which construction plans have been announced.  The  estimated first costs in terms
of $/kw have been grouped by unit size and by year of planned installation.  This is shown
in Figure 35.   Not only does the installed cost/kw rise sharply as unit size decreases,
but a sharp annual upward cost trend is evident for all sizes.  Figure 36  shows estimates
of installed costs by unit size for  all types  of steam-gene rating facilities, including
nuclear, for the year 1974.

      The estimation of  nuclear fuel costs  requires a financial model of its own since the
fuel is purchased (or leased) a year or more before the plant goes into operation.  It is
then treated, used,  repositioned in  the core, processed  with credits accruing to recov-
ered plutonium, and  then reused.  A typical cycle as just described may last from 3 to
5 years.  Thus, the largest  portion of these costs are carrying charges.   How  this invest-
ment is distributed over the energy generated is dependent upon plant capacity  factor,
cost of money, taxes, and other items.   Because analysis of the  costs associated with
nuclear-fuel management is a  science in itself, fuel costs as estimated by utilities should
be used for making the necessary predictions.  This assumes that the installations'
operating patterns and financial costs are similar enough so that serious error is not
introduced by this aggregation. Figure 37  is a 1965 estimate of the trend in nuclear fuel
costs; however, recent experience suggests that this trend is not dropping as rapidly as
indicated.


     Estimates of operating and maintenance expenses for different sizes of nuclear
plants for both 1970  and  1975 are  shown in  Table  26.  Table 27 shows the estimated total
cost of generation in  mills/kwhr for three nuclear plants that are approaching the opera-
ting stage.  These costs are broken down into carrying charges,  fuel costs, and other.
The costs on Brown's Ferry have been adjusted from TVA's to a private  utility's finan-
cial costs.  The data in Figure 37 and Table 26 seem to  fit into the framework  of the
data in Table 27.

     The data were combined to generate a sample calculation which might be  repre-
sentative of a nuclear facility being  planned now for 1974 operation. These calculations
are summarized in Table 28, and the prospects for nuclear generation are, on  the whole,
not so encouraging in the future as in the past.  This picture is largely created by the
sharply increasing first  cost of these facilities,  and for  purposes of comparison, the
same costs have been generated for typical installed costs of 1 year earlier.  This
results  in overall generation costs in mills/kwhr that are  5 to 10 percent lower for facili-
ties starting in 1973 than for those starting in 1974. Since many of  the first costs quoted
for plants scheduled for  operation between  1970 and 1973 are as much as 30 percent less
than the general 1974 cost levels, the rush to nuclear power in this  period is
unde r standable.

     Thus, in expanding the data base of nuclear-generation costs in the immediate
future,  cost estimates of those facilities currently being planned should be relied upon.
A report on nuclear-power-plant activity is published annually in Electrical World(35)
and is a source for data  of this type.

     The staff of Electrical World is also  maintaining a tabulation  of all planned gener-
ating facilities. Appendix B shows the fossil-fuel and hydroelectric portions to

this information will be updated regularly. On the other hand, as soon as some opera-
tional experience is gained on  the larger nuclear stations, fuel costs and operation and
maintenance expenses should be less volatile, and they will be available annually in the
FPC's report on steam-electric generation facilities^-*) in the FPC accounting format.

                  EXAMPLES OF APPLICATION OF COST MODEL
      This section contains a group of figures and a group of tables illustrating the use
of the cost model and its associated data bank. The  figures contain the model forms
used and the solution for the selected situation.  The tables summarize the results which
have been computed for a number of situations believed to be of interest and are illus-
trative of the variety of situations that may be explored with the model.


                                 Detailed Example


      The example (Figures 38 through 43) for the Cook Plant, St.  Joseph, Michigan,
illustrates the use of the model forms for the power  plant without SO£ control and with
the  alkalized-alumina process installed.

      This example  illustrates some of the simplifications that can be resorted to in a
"first-cut" analysis. For example,  although the generating units are started  1 year
apart, the analyst assumed that this was not of great significance since a  20-year period
was being examined. Also, although the load factor  was  assumed to  be decreasing from
an initial 80 percent to 40  percent by the end of the planning period,  it was decided that
the  average.(60 percent) would be used to obtain the  required totals for the planning
period, since year-to-year variations were not considered  of importance  in this particu-
lar  analysis.  If this simplification could not be used,  then  all columns in the  lines used
would have been filled.

      Form S, Summary of Results of Analysis (Figure 39), that follows  shows that in
this case, the incremental cost for SO2-control using  the alkalized-alumina process is
0. 37 mill/kwhr after allowing for credits for sulfur produced. Also,  this incremental
cost is equivalent to $41. 60 for each long ton of sulfur not allowed to enter the atmosphere
as SO2-  Note that in this  particular case the net energy available for distribution was
taken as equal to that generated.  This approach was used because the SO2~control pro-
cess and by-product-plant recurring costs already included a charge for  electrical-
energy requirements; also,  the heat rate used was for the net output of the power plant,
so energy consumption in  the power plant was not considered.  Since the  nonrecurring
and recurring costs for the SO2-control  equipment and by-product plant were  combined
in the type of estimate made, they are not shown separately in Form NR,  Plant Con-
struction and Start-Up Costs,  and  Form R,  Recurring Cost Summary.


                     Results of Specific-Service-Area Analyses


      The model has been used to analyze a number  of situations for service areas which
are believed of considerable interest and illustrative of the results which can  be obtained
through application  of the  model.  The results presented  here are suggested as providing
insight concerning the ultimate problem  being faced.   This  ultimate problem is one of
planning research and development programs so  that greatest efficacy can be  achieved
at the earliest time in the control of SO2 emissions.

      As in the previous two detailed examples, the  data  used for computation have been
obtained from the sections of this  report covering the recommended data on cost

elements.  Details of the computations are not included here since they correspond to
those of the previous complete examples.  Results are shown in a format similar to
Form S (Figure 11) but into which additional information on the elements  of cost, both
nonrecurring and  recurring, have been inserted.

      Examples have been included both for actual planned facilities and for hypothetical
installations.  Some of the examples correspond to facilities under construction  or being
planned by utilities visited during the course of this program.  Thus, a qualitative com-
parison can be made between the results obtained by the utilities in their planning stud-
ies and those presented here.  For simplicity in developing these examples, the analysis
has been performed for a period of only 1  year  rather than the normal period of 20 or
30 years.  In other words, it has been assumed that the operations do not vary over the
period of interest.

      Annualized nonrecurring costs have been computed on the basis of a 20-year pe-
riod using  a 7 percent interest rate for money.   Thus, the multiplying factor would be
13.99 percent, including income taxes,  etc.


New York City Service Area

      For the New York City service area, an analysis has been performed on the basis
of a hypothetical new installation having a generating capacity of 800 megawatts.  The
practice in this area is to locate the generation station within the service area primarily
because  rights-of-way for overhead  transmission lines to lead from remote generation
facilities are not available.

      Three cost examples have been computed.  These are shown in Table 29.  Column
1 shows  a  conventional oil-fired installation, while Column 2 indicates the effect of ad-
ding an alkalized-alumina control device to remove 90 percent of the SC>2 being emitted.
A remote-location alternative is shown in Column 3.  The transmission-line  costs have
been computed for a total length of 340 miles, with the last 40 miles being underground
as would be required because rights-of-way for overhead lines are not available.

      Comparison of the costs for energy delivered to the local distribution network of
New York  City indicates that the penalty for SO2 control by the alkalized-alumina pro-
cess is about 0.40 mill.  In  other words, the value of the sulfur recovered is not suffi-
cient to compensate for the cost incurred in recovery.  This is  further illustrated by the
value of $51/long  ton shown  in Table 29 as the cost for removing a long ton of sulfur.
This is after credit for the predicted net sales  value  of $29. 60/long ton which might be
realized in the 1970 to 1975  time period in the New York area has been taken.

      As indicated by Column 3 of Table 29, the cost of electrical power remotely gen-
erated and transmitted to the New York service area would not be competitive with lo-
cally generated power.  The primary reason for this is the excessive cost for the under-
ground transmission needed over the last 40 miles of the 340 miles total distance.  The
underground portion of this transmission line has been estimated to cost $61  million,
representing 30 percent of the estimated total investment for the project. Without this
requirement for underground transmission, however, a competitive cost might be
achieved for remote generation.

      Another alternative would be nuclear generation,  and this has been indicated as
the way future needs in the New York service area will be  met. Although such a case
has not been computed, the cost for electricity would probably be only slightly more
than the 5. 88 mills/kwhr (say 6. 5 mills/kwhr) estimated for nuclear generation in the
Baltimore area  (see Table 30).  Thus,  nuclear generation  seems to be already more than
competitive with other postulated alternatives,  including local generation without low-
sulfur fuels or without SO2~control processes.


Baltimore Service Area

      A fairly complete set of alternatives has been computed for the Baltimore  service
area.  These are shown in Table 30.  Generation using coal as the  fuel is shown in the
first seven columns,  while that using oil is shown in the next three.  The last column
shows the predicted costs for nuclear generation.

      Included in this set of examples is a computation of expected costs for the  two
SC>2-control processes for which data have been assembled:  alkalized alumina and cata-
lytic oxidation.   Alternative costs for the catalytic-oxidation control process as  shown
by a recent Monsanto brochure'''' have also been estimated (see Column 5).

      Application of the various control processes to coal- and oil-fired operation re-
sulted in  estimated incremental costs of from 0. 39 to 0. 57 mill/kwhr.   The use  of low-
sulfur oil as a fuel is predicted to increase costs by 0.66 mill/kwhr over that for oil of
normal sulfur (3 percent) content.

      Remote generation at a mine-mouth station near Conemaugh  with two 200-mile
transmission lines being used to transport power to the Baltimore  transmission system
does not appear to be competitive either with or without SO? control.  Nuclear genera-
tion (shown in Column 11),  however, does appear to be competitive, as  does the low-
sulfur-oil alternative, with the  alternatives employing any one of the several control al-
ternatives.  Broadly speaking,  the use of oil as a fuel appears to be slightly less costly
than the use of coal at this particular location.
 Central Kentucky Service Area

      Table 31 shows cost estimates for a mine-mouth generation facility in the west-
 central Kentucky region.  This represents the situation for a new unit which might be
 postulated for the mine-mouth Paradise Station on the Green River near Drakesboro.
 Burning coal containing 3 percent sulfur and costing 13i£/million Btu, the  base  cost of
 electrical power is predicted as 4.47 mills/kwhr.  The incremental  cost for SO2 control
 using the alkalized-alumina process would be 0.31  mill/kwhr.
Southeastern Ohio Service Area

      Two examples  are shown in Table 32 for electric power generation in the south-
eastern Ohio coal fields.  For a 600-Mw generating station having two 300-Mw units and
operating at an 80 percent load factor, the base cost would be 5. 10 mills/kwhr.  Sulfur
control through the use of the alkalized-alumina process has been estimated to add 0.44
mill/kwhr to the generation cost.

Northern Indiana Service Area

      Northern Indiana was selected as an example because this represents an area
where future service will be provided by a nuclear facility currently under construction,
i.e.,  at St. Joseph, Michigan.  Table 33 summarizes the results of the cases considered.

      As will be observed,  nuclear  generation is competitive with power generated lo-
cally  burning a 3 percent sulfur coal without a sulfur control device.  Estimated costs
are 5.28 and 5.29 mills/kwhr, respectively.  There is no significance to the variation
in the third significant figure shown; it is carried only for convenience.

      Generation at a  remote location (central Indiana at mine  mouth) with transmission
by twin lines, each  180 miles in length, to the service area would result in a power cost
of 5.81 mills/kwhr.  Obviously,  this alternative is not competitive  even though this is
the one currently in use, with power being transmitted into this service area from both
central Indiana and  southeastern Ohio.

      An interesting result of these alternatives that have been evaluated is that the net
incremental cost for control using the alkalized-alumina process is less for a 5 percent
sulfur coal than for a  3 percent sulfur coal.  Thus, there appears to be merit for  at-
tempting to produce as much sulfur as possible  once the facility  is available.  The com-
parison was made using an assumed constant value for sulfur and on the basis that the
stack-effluent concentration of SO2 was the same  in both  cases.


Salt Lake City Service Area

      Table 34 shows  an example of the estimated cost for a mine-mouth plant serving
the Salt Lake  City area.  The example is for a 40-mile transmission  distance using a
single circuit line,  from the  Castle Gate location east and north of Salt Lake City where
coal deposits  are known to be.  The estimated cost of power, 4.89 mills/kwhr,  is one
of the lower values  found even though fuel cost is not particularly low and transmission
over  a 40-mile distance is required.
Dallas Service Area

      The example shown in Table 35 for the Dallas service area indicates the low gen-
erated cost, 3.67 mills/kwhr,  that can be achieved through the use of natural gas as a
fuel.  In this area close to natural gas supplies,  the fuel cost is low.  Also,  a  generating
station using natural gas as a fuel has the lowest initial as  well as maintenance and other
costs.  Thus, this example probably represents near to the lowest power cost  achievable
in the United States  for a fossil fuel plant.


Los Angeles Service Area

      Shown in Table 36 are cost-computation examples for four alternatives for serving
the Los Angeles  service  area.  An oil-fired facility using oil with 3 percent  sulfur con-
tent is estimated to result  in the lowest cost for generated  power. Somewhat higher in
cost  (by 0.41  mill/kwhr) is a facility using  alkalized-alumina control.  Use of low-sulfur
oil as a fuel would result in an  incremental increase almost double (0. 74 vs  0.41 mill/
kwhr) that for alkalized-alumina control.

      The other alternative explored was remote generation at mine mouth in the Four
Corners area plus transmission over a distance of 700 miles to the service area.   This
alternative is not competitive, costing almost 2 mills/kwhr more than the base case us-
ing high-sulfur oil without control.  However, enlargement of this power-generation
station is under way in this location with the fourth unit,  having a 755-Mw capacity,
scheduled for completion in 1969 and the fifth in 1970.  The only obvious factor that can-
not be evaluated for this alternative is the interaction which undoubtedly exists between
the transmission facilities for power from this location and those serving Glen Canyon
and Hoover Dams.
Tampa Service Area

      The Tampa area, examples for which are shown in Table 37, would normally gen-
erate power using oil containing about 3 percent sulfur as a fuel.  This base case is
shown in Column 1.  Columns 2 and 3 indicate that low-sulfur oil and alkalized-alumina-
control alternatives would be more costly by  about the same increment, 0.47 and 0.43
mill/kwhr, respectively, than the base case.  Generation using coal as a fuel appears
to be cheaper than that using oil.  An interesting alternative,  apparently worth consider-
ing for this area, would be the use of coal as  a fuel with the alkalized-alumina process
being used for control.  This alternative would have an incremental cost only 0. 15 mill/
kwhr higher than that of  generation using 3 percent sulfur oil as a fuel.


Summary of Estimated Costs

      Table 38 is a summary of the estimated costs of power delivered to the distribution
network.  Although not comparable in an absolute sense because of differences in
generating-unit sizes, load factors, etc., some interesting observations are possible.

      Costs for power delivered to the distribution network are about 5 mills/kwhr in
most parts of the United States.  However, there are some significant deviations.  For
example,  for  locations in and near the natural-gas fields where natural gas is used as
the fuel, estimated costs are somewhat lower. The cost in Dallas, which was one of the
examples computed, was estimated to be 3.67 mills/kwhr.  There appear to be two rea-
sons for this. First,  the fuel cost (at 20i£/million Btu), although not the lowest, is in
the lower part of the range.  Second, the capital cost of the generating plant is low, both
because a boiler using natural gas as a fuel has a lower cost and because Dallas is in a
low-construction-cost region.

      The cost of power  delivered to the generation network in New York City can be
contrasted with this; here the cost is the highest of those estimated.  Obvious reasons
are the high cost of fuel  and the high cost of construction.

      Several interesting general trends can be observed by study of this summary table.
Nuclear generation appears to be competitive in all areas except possibly in those regions
where fossil fuel is available locally and can  be obtained without incurring high labor and
transportation costs.  Dallas and Kentucky are prime examples here.

      Remote generation does not appear to be a viable alternative.  The transmission
costs for any significant distance are so large that other alternatives appear to have les-
ser cost.  For example,  rail hauling of coal,  particularly in unit trains, over distances

of 200 miles or more (if there is already a rail line in existence) appears to be cheaper.
The estimates for Baltimore and Northern  Indiana show this.  The New York City esti-
mates for remote generation are more costly yet because of the necessity for under-
ground transmission lines for part of the distance from any remote generation station.

      Using currently available estimates of SO2~control-process costs  as  previously
discussed, Table  38 indicates that incremental costs  for control approximate 0. 5 mill/
kwhr, essentially independent of the two processes costed.  There are variations in this
value, of course,  which depend on the size of the installation, degree of removal,  sulfur
market values, etc. , but the 0. 5 mill/kwhr value might serve as a convenient rule  of
thumb.

      One other feature of interest is the result,  previously mentioned,  that use of a
higher sulfur fuel in conjunction with a control process would result in a slightly lower
net cost  for power.  (See the values  tabulated for the  Northern Indiana service area,
Table 33. )  This  suggests that if a SC>2-control process with recovery of a  by-product is
to be  applied, use of a  fuel with the largest content of sulfur available should be explored.
Modification of this  viewpoint,  of course, would probably be necessary if the monetary
value of  sulfur or sulfuric acid becomes  less.
                                Sensitivity of Results
      Another reason for performing the computations summarized in Table 38 was to
explore the sensitivity of power costs to a variation in each of the  several cost compo-
nents when combined according to the cost-model structure,  A surprising result was
the large influence of transmission distance in increasing the cost of power delivered to
the distribution network.  The results indicate that rail and/or barge hauling of coal and
ocean and/or barge shipment of oil is much more advantageous even for distances as
short as 180 miles.  This conclusion is somewhat in opposition to  current practices as
exemplified by the Northern Indiana and Los  Angeles service-area examples.   Further
exploration of transmission costs  as contrasted to fuel transportation costs thus  appears
to be warranted.

      Although better, more refined data would be desirable on the control-process costs,
this cost component does not appear to be a large factor in the overall power cost.
However,  the value assigned to the sulfur or sulfuric acid does have a large percentage
effect on the control cost and, thus, emphasis  in future efforts should be placed here.
The time variation of these values may also prove to have importance.

      The variation of fuel,  as  burned,  costs with time may also prove to be a signifi-
cant factor. Since fuel  cost represents 25 to 50 percent of the total cost per unit of
power,  the variation of  the fuel cost as  a function of time may have a strong influence.
A situation where this might be expected is the example for the Dallas service area,
where the fuel is natural gas.   Here, a doubling of the price of natural  gas, not incon-
ceivable over a 20-year period, would increase the  cost of power by 50 percent, from
30 67 to 5. 51 mills/kwhr.

      Finally,  the  results obtained are  believed sensitive to plant  factor although no ex-
ploration of the significance of this has  been performed.  This was primarily because
no logic in the manner in which electric utilities perform their planning to account for

                                       127

this factor could be detected.  For the most part, the utilities make  comparisons of in-
teresting alternatives at constant high plant factors of 80 to 90 percent, even though
their  system load factor may approximate  50 to 60 percent.  The influence of such tac-
tics on decisions reached needs to be explored, particularly when control-process needs
begin to influence system operation.

                       CONCLUSIONS AND RECOMMENDATIONS
      Development of a cost model to be used in evaluating the promise of SO2~control
processes has been achieved.  Although the model is not as sophisticated as others de-
veloped in the past for other areas, such as aerospace, a planned balance between sophis-
tication and utility was desired.  Thus,  ease of application and a fair degree of simplicity
leading to short times for computation also exist.

      The cost model which has been described in this report is applicable during each
solution to only one of almost an infinite number of real or assumed situations.  Thus, in
its present form,  costs for various locations,  sizes,  alternatives, etc.,  must be com-
puted individually and compared before any conclusions can be reached.  In other words,
optimization techniques have not been built into the model.

      In using the model, a few limitations should be recognized.  The model will be valid
only to the degree that the input data are accurate. Although a sensitivity analysis was
performed in terms of the computation of numerous examples and alternatives, further
effort is undoubtedly needed to permit discerning the areas where more accurate repre-
sentations of cost are desirable because of the high sensitivity of results to certain cost
representations.  As with all cost-model studies,  the cost data for utilizing the developed
methodology are historically based.  Therefore, periodic refinement and updating need to
be performed.   Finally, time and effort limitations will be recognized.  Analysis for sev-
eral alternatives for a given service area will take a significant time period, perhaps
several days.  Thus, in the present stage of development of the model, judicious selection
of the locations and alternatives needs to be made.

      To be used for planning purposes for SO2~control-process development, solutions
for  a large number of planned facilities  will undoubtedly be needed before a reasonable
assurance as to the "best"  programs can be discerned.  The following activities are pro-
jected as leading to improvements in confidence in the use and utility of the results of the
present model.

      (1)  Development and Maintenance of a Data  Bank

          The  present program provides some data regarding power»plant costs
          and future construction plans. However, in order to keep the cost data
          current and to accumulate enough data from which more reliable cost-
          estimating relationships can be derived, a continuing effort is  required.
          Also, such data should be gathered and  placed in a form suitable for use
          in the model.  The maintenance of such data  should be an ongoing effort.
          The  level of effort required would depend upon the extent of use of the
          model.

      (2)  Early Model Testing,  Utilization, and Modifications

          Beyond the efforts of the present program, it is deemed necessary to test
          the usefulness of the model in a variety of planning problems.   Especially
          important will be the evaluation of data problems  and the amount of effort
          required to perform the analyses.  These initial analyses are expected
          to lead also to identification of needs for model modifications.  These
          activities require management efforts to see that  the user is in a position

          to  report difficulties and to be satisfied that appropriate corrective
          measures are being taken; otherwise, the model will fall into disfavor
          and eventually not be used.  To avoid this it is essential that an aggres-
          sive program of encouraging use and evaluation of the model be followed.
          Also, difficulties should be resolved rapidly so that the model is a viable
          tool of the planner.  This will require more than casual efforts,  and ap-
          propriate in-house or outside-contractor arrangements should be made
          to  insure a proper  conduct of this phase.

      (3)  Computerization

          After the efforts described in (1) and (2) are under way and it appears
          that any difficulties have been resolved, it will then be appropriate to
          consider the desirability of computerizing the model. . This step should
          be undertaken in light of

          (a) Frequency of use of the model

          (b) Manual efforts required for routine and repetitive data manipulation

          (c) Availability of appropriate  data processing personnel  and equipment,
              in-house or on a contractual basis

          (d) Anticipated requirements for further model modification.

      (4)  Extensions of the Model

          Aside from minor modifications of the model, the use of the model in the
          context of R&D planning activities is expected to  lead to considerations of
          extension of the type or scope of what is analyzed.   For example,  the in-
          clusion of more detailed analysis of the impact of developing  alternative
          SC^-control processes  might be treated as a resource  (R&D funds) allo-
          cation problem amenable to solution by techniques  such as "linear pro-
          gramming".  Another possibility is the inclusion of a more sophisticated
          technique for the analysis  of uncertainties  regarding costs and utilization.
          Incorporation of more complex techniques, such as Monte Carlo, will
          probably require use of the digital computer because of more extensive
          requirements for  calculation.

      The specific next steps to be taken in a continuing program for improving the util-
ity of the model and understanding the system which it represents are believed to be
three.  First, a more intensive study needs to be made of the sulfur (and sulfuric acid)
market, particularly the effects which might result from alternative sources of sulfur
(and sulfuric acid) coming into existence.  This area is particularly important because of
the  sensitivity of net  costs for sulfur removal and recovery to the market and "net back"
price for sulfur and sulfuric  acid. A simplified,  gross approach was taken to  establish.
approximate values for use in the current cost model.  Now, a more sophisticated ap-
proach  is  needed in which other independent variables will be considered.

      Second, an improved and enlarged data base would be desirable so that improve-
ments could  be made in the correlations  (cost-estimating relationships) being used in com-
puting the costs of alternatives for accomplishing SOg control,

      Third and finally,  the computation of many more  cases  is needed.  These cases,
and their alternatives, would logically be based on the utilities plans for new power-
generation facilities over the next few years,  as  shown in Table  25 and Appendix  B.  Only
through comparing the costs of various  alternatives  as  they might exist in the different
geographical areas would an understanding of the potential benefits and applications  to be
derived from each of the several SO2~control processes be attained.

      When these next steps  have  been accomplished, a further look into the benefits be-
ing derived should be made to assess the potential for further benefits through, for ex-
ample,  extensions  of the model and/or computerization.

                     MODEL METHODOLOGY AND LIMITATIONS


                                      Background


      The analysis of future costs for the application of various technical approaches to a
problem is an essential part of the long-range planning problem.  This type of analysis is
of special interest to those concerned with the selection between competing research and
development programs.  The competition for available research and development funds
has intensified the need for analyses directed toward early isolation of those programs
with the most attractive technical potential and economic advantage.  This program has
been directed toward providing the long-range planner with a tool for evaluating the im-
pact on the costs of electric power of various approaches to the control of SO2 emissions
from fossil-fuel-burning electric power plants.  The intent is to provide a means for in-
troducing the costs of SO2 control as an additional increment of cost for electric power
generation.

      The approach taken has been influenced by the prior experience  of groups con-
fronted with some of the most difficult cost-analysis problems in the context of long-
range planning, namely, those who  identified the problems and developed the methodology
for the analysis of the cost-effectiveness of future military and aerospace systems.  Al-
though this experience has influenced the approach taken to developing this model, it has
been necessary to avoid a  full-scale adoption of techniques developed by these groups be-
cause of the relatively small amount of effort that is considered presently appropriate
for the class of problems under consideration.

      Typical of the efforts in the military and aerospace field are those described in
Rand reports generated in the post-World War  II period.  For example, Cost-
Effectiveness Analysis:  New Approaches in Decision-Making, (40)* contains several ar-
ticles with a number of references to reports of the Rand Corporation and other organiza-
tions that deal with cost models and cost-effectiveness  analyses.  The article entitled
"Estimating Systems Costs'1'^ °' points out several findings based on experience  with
military and aerospace cost-prediction problems.  This article notes  the importance of
dealing with comparative costs rather than absolute accuracy of costs; in other words,
the costs developed are regarded more as indices that indicate  cost differences and their
extent.   These types of costs are distinguished from those used for, say,  budgeting  pur-
poses.  A major reason for taking this approach is the  uncertainties of future costs.
Related to this argument is the "current dollars" approach, which means that possible
future inflationary effects  are ignored since such effects should not normally affect the
ratio of costs of competing systems.

      Coot-estimating relationships (CER's) play an important role in cost models.  They
are used to determine costs on the  basis of some physical or performance characteristic;
for example, in Figure 14, initial power-plant construction costs are shown as a function
of generating capacity.  CER's are used in place of detailed cost estimates, such as
might be generated for bidding purposes, in order to minimize  the effort required to

generate a preliminary cost estimate,,  Their exact nature depends upon the types of data
available and approach taken to convert the data to a CER.  Statistical techniques, such
as multiple correlation, are frequently used  to generate CER's,  but the technique applied
depends upon the nature of the available data and the level of effort that is appropriate for
the required analysis.  References  (41) and (42) provide a discussion  of the development
of CER's for use in aerospace cost  models.  As the data base regarding power plant and
SC>2-control equipment is expanded, it will be worthwhile to consider  modifications of,
or the use  of more, CER's.
                  /•-'

      Another aspect of the background for model development is the type of financial
analysis performed by electric utilities prior to making investment decisions.  Reference
(43) presents an example of the approach used in this type of analysis.  This type of anal-
ysis places heavy emphasis  on the analysis of tax implications,  return on investment,
discounted present worth, and other "financial factors".  Although these factors  are of
importance to the utility charged with making proper investment decisions, they  have not
been given so elaborate a treatment as found in Reference (43), for example.  This ap-
proach has been taken for two major reasons:

      (1)  The long-range planning efforts  of interest are concerned with the com-
          parison of alternatives to SO2 control, and it is anticipated that the
          "financial factor" applied as a percentage of initial investment costs will
          be the same; hence, the application of these financial factors would not
          alter relative cost standing of the alternatives being considered.  How-
          ever, if significant differences can be anticipated in, say,  taxes or de-
          preciation charges,  then  the analyst must give  more careful consideration
          to the financial-factor aspects of the problem.

      (2)  The complexity of the analysis is considerably reduced by taking a simpli-
          fied approach to the treatment of financial factors0   At this  time it is felt
          that many of the needs for cost analyses can be met by the determination
          of nonrecurring, recurring, and annualized nonrecurring costs.  Until a
          firm need is established on the basis of future problems that will be con-
          sidered by the analyst, the simplified approach to financial factors  ~ which
          amounts to the selection of a percentage to be applied  to nonrecurring
          costs ~ is recommended.

      Hardware costs are usually influenced by the rate and amount of production,, A
"learning curve" is frequently applied to determine the future costs of production items.
Reference (41), for example,  discusses techniques for incorporating  "learning curve"
effects into the cost analysis.   This concept has not been explicitly included in the model,
however, because of the nature of the  initial data base and other considerations:   for ex-
ample, the application of learning curves  requires information as to both initial  produc-
tion costs  for equipment and the anticipated number of equipment items to be produced.
Rate  of production is also of interest since this influences the indirect costs applied in
determining production costs.  The types of data me.de available for  power-plant and
transmission-facility costs  would be expected to already reflect any learning-curve ef-
fects.  However,  it is  speculated at this time that the types of data that might become
available regarding SC>2 equipment  may not include such  effects,  unless the equipment  is
already in production,,  In this  case, if the analyst hypothecates  the broad application of
the type of SC^-control equipment under consideration, he may find it worthwhile to con-
sider the possible influence of learning-curves effects.   But, because of the minimum
concern of this program with SC^-control  equipment costs, this aspect of the analyois  is
not treated further in this report.

      A continual problem with cost models is the reconciliation of the time required for
preparation of input data,  the analysis,  the interpretation of results, and the amount of
time and expense feasible  and  desirable in long-range planning efforts.  The develop-
ment effort for this model has  been influenced by these  considerations; however,  deci-
sions as to the feasibility of pursuing costs to various levels of detail can best be made
only after some model-use experience has been acquired and after decisions have been
made regarding the feasible amount of effort and expense that can be incurred in  the
various planning exercises undertaken by the NAPCA.  Comprehensive cost studies  can
easily require several man-years of effort, and this is  usually infeasible in terms of
the cost of the analysis versus the size of the budget to  be  committed for developments.
Also, the justification for  a large cost-estimating team is  based on the need to analyze
a continuous flow of problems. The adjustment of the costing approach to the amount of
manpower that would be available for cost studies is another important consideration.
Presumably the allowable  costs for evaluations would be a function of the magnitude of
research and development funds being allocated and the complexity of the problems be-
ing analyzed. This model has been developed with these considerations in  mind.


                      Uncertainty and Sensitivity Considerations


      If a cost figure has been obtained,  the planner's next problem is to understand its
uncertainty aspects.  Without this insight, there is the  possibility of selecting a process
whose costs may actually be higher than another because the uncertainties  were not an-
alyzed.  This makes  it important for the analyst to examine the difference  in results
when reasonable variations in  the cost values are allowed.  The recommended approach
is for the analyst to repeat the analysis  using estimates of the highest or lowest possible
values for the cost elements to which the results are  most senoitive.  For  example, fuel
costs may be about 80 percent of the total of annual fuel, operations,  and maintenance
costs.  This would indicate that the results are  more sensitive  to a change of fuel costs
in comparison with,  say,  a minor modification of maintenance requirements.  If the re-
oults of an analysis for comparing, say, a change in fuel with incorporation of an SOj-
control process indicated  that  a 10 percent change in  fuel costs reversed the relative
costs, then the analyst would recognize  the need for a more detailed analysis and im-
proved data - or the introduction of considerations outoide the scope of the cost-model
analysis - before  deciding which approach is superior.

      When the SC>2-control process changes the heat rate  of the plant, this is reflected
directly in fuel costs.  Also, the  control process may require modifications of the power
plant.  When  this occurs,  the  analyst must consider how this affects the  recurring and
nonrecurring costs as obtained for the power plant without SO2 control,,  This requires
examination of costs in more detail, and the  analyst needs some insight as to the rela-
tive importance of the various subsystem and component costs.  Analysis of a subsystem
cost breakdown for TVA steam-production plants indicates that the nonrecurring costs
for each cost element represent the following approximate percentages of total plant
coot:

            Other power-plant equipment           316              1

The column "FPC Account No. "  gives the account numbers as used  in Reference (2),
which describes in detail the components included in each account number.

      The above percentages indicate the importance of boiler-plant equipment in over-
all costsj so emphasis should be placed on understanding the influence  of the SC^-
control process on this cost element. Note the small significance of land  in total costs;
however,  the analyst would want to review the relative importance of this  cost in those
cases where the plant is located  in a metropolitan area.

      The recommended approach to sensitivity considerations is for the analyst to per-
form a preliminary estimate of all cost elements in the model, and  to then base his ef-
forts in cost refinement and "high-low" estimating upon the relative significance of each
cost element in the initial  effort.  High-low estimates are derived from consideration
of what might be reasonable for the worst and best possible areas.  These types of esti-
mates will be improved as experience is developed and the data base is improved.

      A more complex model  could be developed that  would introduce statistical concepts
into the cost estimates,,  Such a model development could eventually lead to the incorpo-
ration of Monte Carlo techniques that introduce random considerations  into the analysis;
that is, explicit recognition is given to the improbability that all costs  will be high, low,
or at the median at the same time [ see Reference  (44)],   However,  such models intro-
duce requirements for many more calculations than the present model. Such a develop-
ment is left for the future  - the investment required must be carefully considered in
terms of needs for analysis and other considerationsc

      In summary, the background of other efforts in developing cost models  provides a
basis  for  considering the modeling problem at hand.  These past developments have in-
fluenced the approach taken.  The following factors also have had strong influence on the
approach  taken:

      (1)  The amount of effort appropriate for the types of analyses of interest

      (2)  The availability  of cost data and the effort required to  collect and/or
          generate new data

      (3)  The uncertainties associated with future  coot estimates

      (4)  Ths desirability - especially from an effort-requirement standpoint -
          of using "sophisticated" techniques.
