Renewables Sector: Alternative Energy Sources

Incentives to Increase Purchase and
Generation of Renewable Energy

Concerned that deregulation of the utility industry would cause a decline
in renewable energy generation, California enacted a law authorizing the
collection of $540 million from investor-owned utilities to be used to
support renewable energy technologies within California. These funds,
collected between 1998 and 2002, are placed in the Renewable
Resources Trust Fund, administered by the California Energy Commis-
sion, and are to be divided between four energy programs or accounts: existing renewables, new technologies,
emerging technologies, and customer side. The funds are distributed as incentives or rebates for those who gen-
erate or purchase renewable energy or for those who install renewable systems. The overarching goal of the pro-
grams is to sustain renewable generation while developing a strong consumer market for renewable power.

Results:

Participation in the California Energy Commis-
sion's programs is still growing, particularly in
the new and emerging technologies accounts.

The annual emissions reductions presented
here are estimated based on performance to
date of the accounts. Some accounts have
been in operation for less than one year; in
these cases, the results were extrapolated to
an annual figure. The customer side account is
double counting between the customer side account and the existing technologies account (some customers
receiving credits for purchasing renewable power may be purchasing it from facilities receiving credit for
producing renewable power). In sum, the renewable energy programs provide financial incentives for over 10
million MWh of electricity each year. If conventional sources were used to generate this electricity instead of re-
newables, an additional 5.8 million metric tons of C02 (1.6 million MTCE*) would be emitted each year. In addi-
tion, the increased renewable energy reduces annual S02 emissions by 140 metric tons** and annual NOx emis-
sions by 1,727 metric tons** compared to conventional sources.

Principal Actors:

California's three major investor-owned utilities were authorized by the California Legislature to collect the funds
associated with the California Renewables Program. The California Energy Commission was authorized to allocate
and distribute those funds.

This case study is based on Renewable Energy Program data provided by Suzanne Korosec, California Energy Commission.
Estimates of emissions reductions were developed by EPA.

*Original data have been converted from kWh and kW capacity to Metric Tons of Carbon Equivalent (MTCE) using the follow-
ing conversion factors: 1.240 lbs C02/kWh (The Cadmus Group, Inc., Regional Electricity Emissions Factors Final Report, The
Cadmus Group, Inc., 1998, Exhibit 6). One metric ton is equivalent to 2205 pounds, one metric ton C02 is equivalent to 0.273
metric tons carbon equivalent (MTCE).

**S02 and NOx emissions were calculated using the following emission factors: 0.03 lbs S02/MWh, 0,37 lbs NOx/MWh (Emis-
sions & Generation Integrated Database (E-GRID), EPA/Acid Rain Program).
