Project Matching: Facilitating New Renewable Energy Projects
Project Proposal Submittal Form

The EPA Green Power Partnership's (GPP's) Project Matching Initiative works to connect stakeholders
with new, not-yet-built renewable energy projects that may align with their energy, environmental, and
financial objectives. The initiative's goal is to spur the development of new renewable generation by
facilitating the signing of long-term green power contracts between end-users and project developers,
thereby providing a guaranteed stream of revenue that developers can use to secure project financing.

The GPP, in collaboration with EPA's RE-Powering America's Land Initiative, will host a project matching
webinar on Wednesday, June 24, 2015. Project developers are invited to submit project proposals to
GPP for possible inclusion in the webinar. This form includes all anticipated criteria that EPA will use to
select projects for the webinar. All projects submitted for review that meet minimum requirements for
data completeness and basic eligibility will be posted on the GPP website. A renewable energy project's
inclusion in this initiative does not constitute endorsement or recommendation by EPA.

Project proposals are due by June 5, 2015 and must be submitted electronically to James Critchfield,
critchfield.james@epa.gov.

Project Summary

Project name: GreenCastle Wind Farm (the "Project")

Developer name: GreenCastle Wind Farm, LLC and NativeEnergy, Inc.

Renewable energy type: Wind
Project city/state: Gilman, Iowa

Project geographic coordinates (To find, use: www.latlong.net/): Latitude 41° 54.983'N, longitude 92°
51.205'W.

Total planned megawatt (MW DC) size: 10 to 15 MW. Final size will depend on specific needs of the
PPA offtaker and investor, and overall financial performance of the Project.

Are there phases? If so, how many and in what size traunches? No. The Project will be built in one
phase.


-------
What is the expected annual output of the completed project (MWh)? 50,500 MWh @ 12 MW total
installed capacity. Estimate is based on nearly eight years of on-site wind data which has been
evaluated by an independent, experienced wind resource consultant. Note that this production
estimate may be confirmed with data from a nearby utility-scale wind project, if such data can be made
available to the Project.

Expected date of construction commencement: May, 2017
Expected date of commercial operation: December, 2017

What is the largest development hurdle and how is it anticipated to be overcome? Securing an
investor. Lack of an attractive PPA has been the limiting factor in attracting investors. To date, there
have been no regional utility buyers interested in entering into a PPA at a rate which will make the
Project financially viable. The Project is exploring (in part, via this EPA webinar) alternate power and
REC offtake arrangements with end-users attracted to smaller wind projects that promote distributed
wind energy benefits and provide local community-ownership and strong REC or carbon credit
marketing/public relations characteristics.

Can you provide examples of similar projects you have developed? This is the first project developed
by GreenCastle Wind Farm LLC. The individual controlling members of the LLC are the landowners and
owner/operator of the Project and have a family history of farming in the community for 60 years.

NativeEnergy has been involved in financially supporting community wind projects for 15 years by
directly leveraging the REC and carbon credit markets. The company has helped advance over 40 wind
energy projects on behalf of its many corporate clients across the U.S. NativeEnergy's clients are
motivated to support these projects to meet their corporate sustainability objectives and the desire to
support projects with additional societal benefits beyond just the verified carbon emissions reductions.

Site Readiness

Has the project received all necessary federal, state, and local permits to proceed with construction
and operation? If not, please outline the key permits required to proceed with project
construction/operation and describe the steps you have taken in order to evaluate and address
permitting risk for this project.

•	Marshal County Zoning Special Use Permit has been granted.

•	Project will apply for a Marshall County Building Permit once project financing and construction
is confirmed.

•	Project will apply with the FAA regarding the administration's "Notice of Proposed Construction
or Alteration - Off Airport" once final turbine size and locations are confirmed.

•	A noise analysis has been completed for the project site, assuming a 6 x 2 MW layout. Results
from this analysis indicate the Project will not emit noise levels of concern at residences of non-
participating land owners, consistent with the Marshall County Zoning Special Use Permit.

•	An avian species report has been completed for the project site, assuming a 6 x 2 MW layout.
Results from this report indicate that the Project will unlikely have a detrimental impact to avian
species present in the area.

•	Project has developed a turbine Decommission Plan consistent with the Marshall County Zoning
Special Use Permit.

•	No other permits are expected at this time.


-------
Note that the Project site is approximately 4 miles from the 120 MW Laurel Wind Farm which began
commercial operations in December, 2011. Given the close proximity and large size of this existing
large wind farm project relative to the proposed 10 to 15 MW GreenCastle Wind project, permitting
risk of the Project is expected to be very low.

Have you secured long-term site control? If so, please describe the nature of the agreement (lease,
ownership, etc.)? Yes. Controlling members of GreenCastle Wind are the landowners.

Have land leases been filed with the county? No.

Does the project require either an Environmental Impact Statement or Environmental Assessment? If
so, what is the status? The Project will not require either of these assessments.

Is this project sited on a current or formerly contaminated land, landfill or mine site?1 If so, has the
site addressed the related environmental issues? No. The Project is not sited on contaminated land.

Interconnection

What is the status of interconnection, and have system impact and facility studies been completed?
(Distribution or transmission level projects are both eligible) The Project initiated a System Impact
Study with Central Iowa Power Cooperative (CIPCO ) on May 13, 2010 using a 15 MW project
configuration connecting to CIPCO's 34.5 kV line. The study completed flow analysis and assessed
constrained interfaces. The results showed that the Project is small relative to the system and "will
have no adverse impact on regional flowgates or local area facilities, therefore no transmission network
upgrades are required in order to approve the interconnection and transmission service." Input from
the Midcontinent Independent System Operator (MISO) was also provided in this study.

A Siemens Energy, Inc. study was also conducted to support CIPCO, and completed on November 29,
2011. The study performed transient stability analysis under the same proposed 15 MW configuration
connecting to CIPCO's 34.5 kV line. The results of this study similarly concluded that the Project "does
not have a detrimental impact on the stability of the local area transmission system."

When do you expect the interconnection study process will be complete? Given the time that has
passed since the above studies were completed, it is expected that this process will need to be revisited
to account for any new conditions of the regional system. However, given the relatively small size of the
project, it is unlikely that the Project will create any impacts that were not identified in the original
studies. Based on progress with a PPA buyer and subsequent financing, the Project will reengage with
CIPCO to upgrade these studies.

Does the transmission owner (TO) or independent system operator (ISO) have a process to study the
project's impact on the local or regional grid and the subsequent cost to interconnect? Yes. The
Project is located in the MISO, and MISO has an established generator Interconnection Procedures and
Requirements. Note that this process provides a fast-track process for projects no more than 5 MW and
may be considered pending feedback from interested PPA and financing parties.

Operation & Financing

Is any element of the project - technology or systems - experimental or pilot-phase or proven
technology? No. The Project will employ commercially proven and available wind turbine technology.

1 Examples of such properties could include brownfields, municipal solid waste landfills, abandoned mine lands,
and Superfund sites, among others subject to state or federal authorities or cleanup programs.


-------
What is the long- and short-term plan for operating and maintaining the project? The Project is
expecting to enter into an O&M services agreement either with the turbine vendor or
qualified/experience third party.

For wind projects, has a meteorological tower been installed? If yes, when was the tower installed
and how much data has been collected? Yes. A 50-meter meteorological tower was erected on July
12, 2007. Data is still being collected and a recent assessment of this data and resulting energy estimate
of a 12 MW project configuration has been performed.

Provide a short summary of how you view project finance and structure/ownership taking shape for
this project: Currently, the primary focus is to secure a long-term PPA with a credit worthy buyer at a
rate that is financially viable for the Project. Once the PPA is secured, the Project will use its available
contacts to engage with one or several qualified parties with an interest in investing in wind energy
projects of this scale and timeframe.

Individual controlling members of GreenCastle Wind have been approved to receive the Iowa State
Production Tax Credit (Iowa Code Chapter 476C) for its eligible, proposed wind facility. Under this tax
credit incentive program, 51% of the project must be owned by an Iowa entity; the individual controlling
members of GreenCastle Wind LLC will be the Iowa entities.

Partners

In what ways can organizations participate in the project? (Check all that Apply)

13 Power purchase agreement for bundled power and RECs
13 Financial hedge or contract for differences

~	Long term REC offtake

13 Financial investment / ownership stake

~	Other, please specify:	

What are some of the characteristics of your ideal power purchaser, investor, or other partner? The

ideal power purchaser will be specifically looking at a smaller project with attractive marketing and PR
benefits that a larger utility-scale wind farm typically cannot provide. Consequently, the power
purchaser will be seeking RECs in the range of 50,000 MWh per year, or higher value verified carbon
emissions reduction credits of approximately 35,000 tC02 per year. The power purchaser will also have
the capacity to accept the risks associated with the local LMP market pricing if the Project's PPA is
ultimately crafted as a merchant plant/hedging structure/CFD, along with the additional costs to
manage such a structure. These risks will, in part, be offset by the Project's modest size (if the power
purchaser's overall energy needs are markedly larger than 50,000 MWh), extensive historical wind
resource data, and well-understood development/permitting of MW-scale wind turbines in Iowa.

What marketing opportunities exist at the project? As noted above, due to its smaller size and
distributed nature, the Project affords several marketing opportunities that do not exist for the typical
larger wind farms that attract larger corporate end users.

• The Project landowners and owner/operators are local farmers that are members of the
community and have a family history of farming for 60 years. The financial benefits that they
receive from the project will supplement and strengthen their farming income. The generally


-------
consistent and predictable annual returns received from the Project will provide a hedge against
potential year to year volatility associated with farming.

•	The majority of the revenues the local Project owner/operators receive are expected to remain
in the community simply due to the fact that they are a local business and, thereby, pay local
taxes, provide employment locally, and purchase local goods and services.

•	Smaller electric generation projects able to connect to distribution-voltage transmission lines
can provide certain distributed generation benefits. Multiple distributed generation projects
spread out across the distribution grid should be encouraged.

•	Smaller projects typically face economies of scale challenges and are less attractive to
conventional PPA offtakers. However, due to the attractive aspects associated with the
marketing of the RECs or carbon emissions reduction credits, and the relatively modest PPA
volume commitment, these small projects can appeal to a client base that has yet to have many
opportunities in which to participate. The success of this project will provide a proof-of-concept
for future similar opportunities around technically feasible but financially stalled distributed
energy projects in need of PPAs.
