SECTION 2 – PROJECT SUMMARY
Provide a brief 1-2 page overview of your project.
2.1 PROJECT TYPE
Describe the type of project you are proposing, (Reconnaissance; Resource Assessment/
Feasibility Analysis/Conceptual Design; Final Design and Permitting; and/or Construction) as well
as the kind of renewable energy you intend to use. Refer to Section 1.5 of RFA.
Golden Valley Electric Association is seeking funding through the Renewable Energy Fund to
complete final design and permitting and construction phases of its Eva Creek Wind Project.
GVEA is a not-for-profit, rural electric cooperative providing electric service to a large area in the
Interior of Alaska, including residents from Cantwell through Healy to Nenana along the Parks
Highway to Fairbanks and then along the Richardson Highway to North Pole and Delta Junction.
As a not-for-profit cooperative whose mission is to provide the best electric service at the lowest
possible price to its members, GVEA cannot assume the financial burden of these two final phases
to complete the Eva Creek Wind Project without impacting the electrical rates of its 33,000
members and the communities served. Given its investment in infrastructure* in the last decade
that substantially improved GVEA’s ability to serve its members, GVEA must pay off its debt
while at the same time look for ways to reduce its dependency on oil to generate electricity. GVEA
has been a leader in the state for its commitment to renewable energy and promotion of renewable
energy through its successful Sustainable Natural Alternative Power (SNAP) program, and its
development of a Standard Power Purchase Agreement for member-owned small-scale renewable
energy projects. GVEA does not have the benefit of consistent access to natural gas as is possible
in southcentral Alaska even though its North Pole Expansion Plant has the capacity to run plant
turbines on either oil or gas.
However, now is the time to implement a “can-do, project-ready” alternative energy project to
really benefit the 100,000 plus Interior residents in the GVEA service area; moreover, it can be
accomplished within a reasonable timeframe to provide relief during this period of rapidly
escalating and “homeowner crippling” energy prices.
Public power utilities across the nation are developing diverse portfolios, including success with
wind power. Wind cannot displace the need for oil-fired capacity, but it certainly can offset the
dependency by reducing the amount of fuel oil burned. Wind power requires backup turbines when
wind can’t deliver. Significantly, with this project GVEA estimates it can achieve a direct offset of
fuel from a 24MW wind generation project that operates at a 33% capacity factor. At the current
price of almost $3/gallon for oil GVEA would anticipate savings between $11 to $15 million on
fuel purchases annually for the life of the project. That fuel cost comes directly off membership
bills. The fuel and purchase power component of our members’ bills has nearly tripled in the last
year.
GVEA through this grant expects to generate wind power from Eva Creek at a cost to its
members of 8-to-9 cents a kw/hr. This is a cost that is similar to what GVEA presently purchases
Natural Gas Economy Power energy and that is equal to the cost of energy that Anchorage
consumers pay—a cost which would be half the cost of GVEA’s oil-fired energy. Furthermore, by
owning the power generation this 8-to-9 cents kw/hr cost is nearly half what the 13-to14 cents cost
the market might bear if GVEA chose to purchase wind power (GVEA’s current avoided cost).
All the more reason for GVEA to develop, build and own its own wind generation—it provides
the best method to achieve substantial diversity to include alternative energy in a meaningful way
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 4 of 77 9/2/2008
in its energy mix, while, and importantly, keeping in mind the cooperative principle to achieve the
lowest price possible for its members. GVEA is the second largest electric utility in the state and
its location in the Interior means it can through this grant provide a large population with quality
electric power at the best price possible without having to negotiate with market driven
entrepreneurs who will certainly want to make money on the sale of wind power.
Grant funding would enable GVEA to have a project up and running within 33-to-36 months
and reduce the cost of electricity for its members. GVEA believes it can concurrently complete the
requirements for the Final Design and Permitting Phase and the Construction Phase based on its six
years plus of reconnaissance, resources assessment and feasibility analysis—all conducted with
GVEA resources totaling $1 million. GVEA has invested in four years of wind data collection,
feasibility studies, has had preliminary discussions with permitting agencies, talked with the
immediate community to be affected about the project, received estimates of costs two years
previously which have been updated for this request, has the staff to oversee a project of this
magnitude and is a leader in alternative energy.
GVEA’s pioneering experience with wind technology and its integrated resource planning
model for assessing current and future energy needs target wind as the best option for major
development among the renewable energy sources.
Importantly, GVEA cannot afford to accomplish this project without this grant. The long-term
economic benefit of this project is that upgrades and expansion are easy—permitting has been
accomplished, infrastructure is paid for and the area offers room for expansion. Lessons learned
from this project could be used around the state; and significantly, additional generation could be
added at the proposed project site allowing other Railbelt utilities to add additional wind
generating capacity for much less cost than duplicating the initial investment.
Finally, Golden Valley Electric Association looks at wind ownership similar to its approach to
conventional generation—utility-owned generation is for the long-term and can be a hedge during
periods of extreme market volatility.
*NOTE: CHANGES TO THE GVEA SYSTEM
GVEA has undergone a period of significant capital expansion in response to its growth rate in the past
decade. We constructed the North Pole Expansion Plant, the Northern Intertie, the Battery Energy Storage
System, the Carney line, and moved the Chena 6 unit to become the Delta Power Plant and added an SVC
in Delta. In large part, these additions have made the GVEA system far more reliable that it used to be,
recently completing over four years between blackouts, doubling our previous best.
The North Pole Expansion Plant, an LM6000 with a steam back end, can produce over 60 MW. The
plant runs on Naphtha which is a very low sulfur fuel required by our air permits. The plant was designed
such that the output of the plant can be easily doubled while minimizing replacement of existing hardware.
The unit and facility were designed to allow easy conversion to natural gas when that becomes available.
The NPEP met the goals of excellent efficiency and provided the ability to accommodate possible future
expansion and fuels.
The Northern Intertie provides a second path between Healy and Fairbanks, approximately 97 miles. It
was built to 230 kV standards for the future, but is currently energized at 138 kV.
Prior to this line, any fault on the old line would result in severe outages since it would separate GVEA’s
load center from not only the Alaska Intertie but also our Healy generation plant. Any scheduled
maintenance was extremely expensive on the old line as it resulted in our inability to purchase less
expensive economy energy from Anchorage, the ability to use our Bradley Lake resources and we often had
to send Healy coal power south at a loss since thermal cycling of a coal plant can lead to increased
maintenance.
Several such outages were averted in 2006 during the Parks Highway wild fire. The fire moved under
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 5 of 77 9/2/2008
the old line on several occasions that summer often resulting in trips. For safety reasons, the fire service
requested the old line to be de-energized whenever they had crews or low flying aircraft in the area which
was easily accomplished since we had the Northern Intertie in service.
Since the Northern Intertie runs in parallel with the old Healy to Gold Hill 138 kV line, the current in the
old line is cut approximately in half which reduces losses in a squared fashion. At high loads on the Alaska
Intertie (typical), the losses are reduced by approximately 5 MW/hour. This results in a savings of almost
$6M/yr. (based on GVEA current avoided cost tariff).
The Battery Energy Storage System (BESS) provides 4 quadrant power (MW in, MW out, MVARS
leading, and MVAR lagging) and can do so very quickly, typically on the order of a few cycles. In the
current configuration with 4 strings of batteries, it passed commiss ioning by providing over 30 MW for 15
minutes and can go up to 46 MVA, but for a much shorter time frame depending on power factor. The
facility and major equipment is sized to accommodate possible future expansion of up to 8 strings of
batteries.
BESS was built in conjunction with the Northern Intertie. BESS has the ability to not only regulate
voltage like an SVC, but can quickly inject real power to the load center to reduce loading on the old line
should the Northern Intertie trip out.
BESS has been engineered to provide additional value to GVEA. The high cost of liquid fuel in the
Interior has always made carrying spin a very expensive proposition. Consequently, we have used SILOS
(Shed-In-Lieu-Of-Spin) instead of running additional units. We now have BESS inject power when the
other utilities are in need of our spin and only start additional units after the fact as necessary instead of
running them continuously waiting for a problem. Additionally, in the past, if the Intertie was overloaded,
we would automatically shed load to get it back to normal quickly before the overload progressed to a trip.
We now use BESS to inject power on Intertie overloads which has allowed the System Dispatchers to
schedule closer to the edge by purchasing additional economy energy without fear of shedding members on
small bumps to the system.
BESS has been programmed to inject MW (if appropriate) when other GVEA transmission lines trip, or
on the trip of our generators which lessens the impact on the other uti lities as well as ourselves. As of mid
2008, BESS has operated 255 times and has prevented an average seven outages per meter per year.
The Carney Line runs between North Pole Industrial Sub and the Carney Substation, approximately 23
miles. This 138 kV line plugs the last gap in GVEA’s 138 kV transmission system; this backbone now runs
continuously from Healy to Fairbanks to Delta. The old 69 kV lines in this region are still in service, but
would be above their limits with the load growth that we’ve had in the Delta area and would not be robust
enough to allow motor starts in the Delta area without exceeding our flicker standards.
The old Chena 6 Unit in downtown Fairbanks was relocated to Delta to serve as the Delta Power Plant.
It is a 23 MW diesel fired combustion turbine. In its old location at Chena Plant, the output was restricted
to approximately 18 MW due to transmission constraints. Moving the existing unit was significantly less
expensive than purchasing a new unit and since the construction of the NPEP was in progress; there was no
need for additional capacity.
The unit was relocated in response to the significant growth that GVEA was experiencing in the eastern
portion of our system. The Delta area is served by a single transmission line and went from representing
5% to becoming 20% of our total system load. This unit allows energy to be restored to the area in the event
of the loss of this line within 15 minutes, or allows maintenance to be done on the line with no interruption
to the membership.
The Jarvis Creek SVC is a Static VAr Controller (voltage regulator) in Delta AK. It has the ability to
supply up to 45 MVAr leading (capacitive) to 8 MVAr lagging (inductive). A voltage controller was
needed in the Delta area due in part to the large increase in loads see there as well as the type of loads, i.e.
large motors that are started, trip, or are shutdown.
The Additions of Pogo Mine and Alyeska Pipeline have helped reduce the risk of constructing NPEP
and the Carney Line. The Teck Pogo mine on the Good Pasture River is a large underground gold mine in
the eastern part of the GVEA system. Pogo built and owns a 138 kV line that runs down the Shaw Creek
valley and connects to our 138 kV line that runs to Delta via the P ogo Tap Substation. The mine consumes

approximately 10 MW and they have backup generators, but have to be disconnected from us when they run
these as they didn’t install synchronizing gear. Pump Station 9 is a TAPS pump station located south of
Delta. An extra two miles of 138 kV line was built to reach the site. The station has several pumps, not all
of which are on at any given time. P9 was designed to take up to 18 MW but consumes approximately 9
MW due to lower flows in the pipeline. Both projects exhibit a fairly flat profile around the clock and
throughout the seasons.
2.2 PROJECT DESCRIPTION
Provide a one paragraph description of your project. At a minimum include the project location,
communities to be served, and who will be involved in the grant project.
GVEA has been monitoring the wind resource at the Eva Creek Site since 2003 or for five years
and has found a resource with approximately a 33% to 36% capacity factor. The Eva Creek Wind
Project’s proximity to the Northern Intertie is key to its value, making the interconnection viable.
The site is located on the east side of the Nenana River near Ferry, Alaska, in the GVEA service
territory in the Interior. The area could support up to 150 MW of wind generation but GVEA
would like to start by installing a 24 MW wind project.
The proposed site is on a dirt road system that was developed to provide access to numerous
mining claims in the area which would need some improvements,. The dirt road system is not
connected to the highway system. Currently, access is gained by walking across a Railroad bridge.
Some infrastructure improvements will need to be made including road improvements for access to
the site, a substation, and a way to get equipment across the Nenana River.
Eva Creek is located near Ferry, Alaska, near Healy off the Parks Highway. The entire GVEA
service area will be served by this renewable energy project and the entire Railbelt potentially
could be served by future expansion. GVEA has had an alternative energy team in place for the
past decade. Wind has been a focal point of interest and investment. In 2002 GVEA contracted
with Sterling Management Services to begin a series of studies evaluating the potential capacity of
several sites within the service area after which it became clear Eva Creek had the best potential
for success.
Communities to be served: GVEA service 3,893 square miles extending 130 miles south
including communities from Cantwell on the Parks Highway north through Healy, Anderson,
Nenana, Ester, Fairbanks and 100 miles south on the Richardson through North Pole and Salcha to
Delta Junction. More than 100,000 residents are in the area with 33,000 members and 43,000
meters.
The members of the team who will be involved in the grant project will combine the talents and
experience of existing GVEA staff and wind expert consultants and at the appropriate time the
contractor for construction. GVEA personnel and contracted consultants will be working on this
project. The GVEA team includes:
Kathryn K. Lamal, Vice President of Power Supply, GVEA
Mike Wright, PE, Vice President of Transmission and Distribution, GVEA
Tim DeVries, PE, Manager of Engineering Services, GVEA
Paul Morgan, Wind Specialist and Alternative Energy Team member, GVEA
Daniel R. Bishop, PE, Senior Engineer, GVEA
Henri Dale, PE, GVEA Power System Manager
Paul Parks, PE, Power Supply Engineer, GVEA
Sterling Energy Management, LLC of California is the contractor wind consulting firm, naming
senior consultants Ron Fawcett, Jake Drews and Jon Lantz to this project.

2.3 PROJECT BUDGET OVERVIEW
Briefly discuss the amount of funds needed, the anticipated sources of funds, and the nature and source of
other contributions to the project. Include a project cost summary that includes an estimated total cost
through construction.
To complete the final design and permitting process and to construct the 24 MW 16-turbine
(assumes 1.5 MW turbines) wind farm at Eva Creek GVEA has estimated a project budget of $93
million through construction. We expect to contribute 15 percent of the funding ($14 million) to
complete the Eva Creek Wind Generation project.
Our members have urged the board to commit resources to alternative energy and GVEA has
conducted preliminary studies on wind generation in response to that interest as demonstrated by
those who are willing to contribute to the SNAP program. In addition, our members voted in 2006
to have GVEA continue to own its power generation, as well as transmission and distribution. This
is clear direction about how we need to proceed and we believe our early work in wind makes us
project ready to get these final phases completed in time to really help Alaskans facing extreme
energy costs in the Interior.
However, and importantly, GVEA could not afford to construct the Eva Creek Wind Project
without funding through this grant. We cannot commit membership dollars that would increase the
cost of power just to achieve Green Power efficiencies and to diversify our energy mix with more
renewable sources of energy. We are required to deliver quality electric power at the best price
possible for our members. Implementation of this project through construction not only reduces
our carbon footprint, but also, the bottom line is it reduces the cost of electricity for our members.
We are a cooperative bound by cooperative not-for-profit business principles—not a company that
can choose to make money through the sale of electricity.

2.4 PROJECT BENEFIT
Briefly discuss the financial benefits that will result from this project, including an estimate of economic
benefits (such as reduced fuel costs) and a description of other benefits to the Alaskan public.
Completion of the Eva Creek Wind Project will result in direct economic benefits to GVEA’s
33,000 members and its customers in the Interior—100,000 residents in the communities of
Fairbanks, Nenana, Healy, Anderson, Delta, North Pole, Salcha and others along both the Parks
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 10 of 77 9/2/2008
and Richardson Highways are served. There is no doubt the completion of a successful wind
generation project in the Interior within the next 33-to-36 months will contribute significantly to
the economic stability of the region. Fuel costs have nearly tripled for some as they are being hit
with the high costs of heating oil, gasoline and electricity, which for GVEA is dependent to a large
extent on the use of oil for its electrical generation at the North Pole Power Plant . We know wind
cannot be the only answer, but we have learned, as a result of the studies of the past six years, that
wind capacity of 33-to-36% is evident at Eva Creek and wind needs to be part of the mix for
future electric power generation. Nationwide electric customers are supporting their utilities efforts
in developing renewable energy; and GVEA has had an active Green Power committee which
helped shape the board’s renewable energy strategy for the cooperative. GVEA met 2007 board
goals of its Green Power Pledge to use 10% of the 2007 peak system load (223 MW) with
renewable sources and has committed to meet a 20% goal by 2014.
The fuel and purchase power component that GVEA has had to impose on its members in
recent years jumped dramatically this past year. Approximately $100 out of the average GVEA
member homeowner’s electric bill of $167 is going toward the fuel and purchase power
component. GVEA is in the unique position of having six years of reliable data on the feasibility
of wind availability on our system with specific wind data since 2003 for Eva Creek as a site for
what is likely to be the Unites States’ largest Arctic wind generation project .
With this grant GVEA can immediately go to work to complete the permitting/design and
construction phases within a timeframe that can make a real difference in the cost of electricity for
its members. GVEA is not in the business of making a profit—it is in the business of generating
and delivering electricity to its members at the lowest cost possible. This is an underlying and
essential cooperative business principle.
Resource diversification will be essential given geopolitical, environmental and technical
pressures which will result in volatile fossil fuel prices.
In addition to the benefit of reducing our carbon footprint through the integration of renewab le
energy sources into our system and the benefit of reduced costs to our members, there are other
benefits to the state of Alaska as a whole. For example, with the investment in this infrastructure
and the lessons learned from completion of this first major Arctic wind generation project in
America, GVEA contributes to the understanding of the challenges of such construction in
northern climates. Any future installation should be easier because of this “model” project. Of
special significance to Alaska, is the capability to expand the system to provide renewable energy
to other Railbelt Utilities at a cost far less than the initial investment. The Eva Creek site can
accommodate expansion; it will have already been permitted and early operation will work out and
resolve any unanticipated issues. Another benefit is the ability of the Interior and Fairbanks to
build an image of a clean energy destination which has had an impact elsewhere on attracting
conventions, travelers, new residents and businesses to an area. Finally, this project will develop a
skilled workforce to operate and maintain wind generation systems.

Grant Application
AEA 09-004 Grant Application Page 15 of 77 9/2/2008
Detail project activities completed to date,
Identify existing or potential problems not previously anticipated,
Outline the activities targeted for the next reporting period, and
Provide project photos to demonstrate progress on the project especially when it gets to
the construction phase.
The quarterly report will also account for expenditures to date and identify discrepancies
between budget and new cost estimates.
Other required reporting requested b y AEA will be accommodated.
3.6 Project Risk
Discuss potential problems and how you would address them.
The greatest risk of any wind project is the availability of wind, and in this instance we know we
have a consistant wind resource as a result of our six years of work studying wind resources in
the GVEA service area. Meteoralogical towers which have been on-site since 2003 demonstrate
we have a good wind capacity factor of 33 - 36% at Eva Creek.
The construction risks associated with the Eva Creek Wind Project will be similar to the
risks of any construction project in Alaska. There is nothing we have uncovered through
feasibility studies and our understanding and experience in working during the Interior’s limited
construction season that we believe will pose problems to prevent a successful installation. With
funding we can move ahead relatively quickly to secure the required permits and mitigate
concerns.
Environmental issues can be a potential problem; however, in this case GVEA has recent
experience obtaining permits in the proposed project area during the permitting process for the
Northern Intertie. Specific permitting and environmental issues are discussed in Section 4.
The location of the proposed wind project will make construction more of a challenge.
GVEA will need to make road improvements as part of the project. GVEA’s construction
experience with the Northern Intertie will likewise prove valuable during this project.
Availability of large WTG’s is also a risk factor. Large WTG’s are in demand and there are
many projects planned throughout the lower 48 over the next few years. GVEA has been in
discussions with WTG vendors to ensure availability if this grant application is approved.
System integration of a large WTG project on GVEA’s system may be an issue. GVEA is in
the process of completing a wind integration study to determine any system upgrades that may
be required. Required upgrades will be incorporated in the system design. For example modern
wind turbines can be specified with zero voltage ride-through where in the past wind generation
was tripped off-line during system faults. Modern turbines can also provide reactive
compensation in order to help with voltage stability issues.

SECTION 4 – PROJECT DESCRIPTION AND TASKS
Tell us what the project is and how you will meet the requirements outlined in Section 2 of the
RFA. The level of information will vary according to phase of the project you propose to
undertake with grant funds.
If you are applying for grant funding for more than one phase of a project provide a plan and
grant budget for completion of each phase.
If some work has already been completed on your project and you are requesting funding for
an advanced phase, submit information sufficient to demonstrate that the preceding phases
are satisfied and funding for an advanced phase is warranted.
4.1 Proposed Energy Resource
Describe the potential extent/amount of the energy resource that is available.
Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be
available for the market to be served by your project.
The Eva Creek Wind Project is planned to be a 24 MW wind farm located on the east side of the
Nenana River near Ferry, Alaska, in the GVEA service territory in the Interior. Preliminary wind
resource studies indicate that the gross capacity factor for this project would be approximately
36% with a net capacity factor of approximately 33%. This capacity factor translates into an
annual energy production of 68.5 GWh.
[Note: Benefits are addressed in Section 2 above.] The Eva Creek Wind project would provide
clean, renewable energy that would (a) reduce the emission of greenhouse gasses, (b) help GVEA
meet its renewable energy pledge of 20% by 2014, and (c) support Federal facilities in GVEA’s
service area meet their green mandates. Furthermore, the cost of production (including capital
recovery) would likely be below the variable cost of generation for many of GVEA’s ex isting
generation resources.
The Eva Creek project would be subject to intermittent energy generation that would
necessitate daily resource regulation planning which would likely result in periodic inefficiencies
in operation of its existing assets.
GVEA has a diversified mix of generation as discussed previously in this application. Other
alternatives to wind in GVEA service territory are biomass; hydro, solar and geothermal. The
Fairbanks North Star Borough is in the process of reviewing bids for a biomass generator located
at the landfill. GVEA has been contacted concerning purchasing the power from this project. The
proposed projects are relatively small and will not be sufficient to meet GVEA renewable energy
pledge. The cost of power may also come in close to avoided cost which would provide no rate
relief to GVEA’s members. Solar is too costly at this time; however, GVEA does support small
scale solar projects through the SNAP program. GVEA has received grants to study hydro
resources along the Nenana and Tanana rivers. The studies may show that there is availability of
run-of-river hydro in our service territory; however, there is little elevation differential so a large
scale hydro may not prove feasible. GVEA does support the renewed study of the Susitna Hydro
project and would enter into a power sales agreement if the project were to move forward. There
has recently been the development of a small geothermal plant at the Chena Hot Springs Resort
east of Fairbanks. The challenge at this time is that there has not been a sufficient geothermal
resource identified to make a large scale project viable.

AEA 09-004 Grant Application Page 17 of 77 9/2/2008
There have been several investor owned groups that have contacted GVEA about the
possibility of GVEA purchasing wind generated electricity. An investor owned wind project
would be an option for GVEA to achieve its renewable pledge; however, a non-regulated investor
owned wind project would not reduce energy costs to GVEA members.
4.2 Existing Energy System
4.2.1 Basic configuration of Existing Energy System
Briefly discuss the basic configuration of the existing energy system. Include information about
the number, size, age, efficiency, and type of generation
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 18 of 77 9/2/2008
GVEA is a not-for-profit, rural electric cooperative providing electric service to a large area in
the interior of Alaska, including residents in the Fairbanks, Delta, Nenana, Healy, and Cantwell
areas. The GVEA mission statement is “To provide our member-owners and communities with
quality electric service, quality customer service and innovative energy solutions at fair and
reasonable prices.” To meet this objective, GVEA relies on its self-owned generation,
transmission, and distribution facilities described in this section and depicted in Figure 2 -1. It
also participates in firm and non-firm power purchase exchanges.
GVEA currently operates and maintains 3,047 miles of transmission and distribution lines and
36 substations. GVEA transmission facilities extend as far south as Healy, north to the Ft. Knox
substation, and southeast to the Jarvis Creek substation and to Alyeska Pump Station 9. The
system is interconnected with Fort Wainwright, Eielson Air Force Base, the University of Alaska -
Fairbanks, and the electric utilities in the Railbelt by way of the Anchorage-to-Healy Intertie (AH
Intertie). GVEA is the northern control point for the AH Intertie, which has a maximum rating of
79 MW of transfer capability. The AH Intertie is owned by the State of Alaska and operated under
multi-party agreements.
Currently GVEA has a total firm capacity resources of 258.6 MW (peak winter ratings),
comprised of 217.6 MW of self-owned generation capacity, 20 MW from Bradley Lake, and 21
MW of firm energy purchases from Aurora Energy. The primary characteristics of these
resources are shown in Table 2-1. As seen in the table, GVEA’s existing capacity is a mixture of
combustion turbine (190.6 MW), coal (27 MW), contracted hydroelectric capacity (20 MW) and
contracted coal (21 MW). Most units have already achieved a long service life wilth all
combustion turbine units except for the new combined-cycle plant on-line prior to 1977, and the
coal (Healy) facility has been in operation since 1967. The Bradley Lake hydroelectric facility is
relatively new, however, as it came on-line in 1991 and, as with most hydroelectric facilities, is
expected to have a unit life of 50 years or more. As shown in Figure 2-1, the GVEA generating
plants are dispersed in and around Fairbanks, with the exception of the Healy coal unit and
Bradley Lake.
Table 2-1 also lists the fuel type and heat rate of the GVEA resources. GVEA’s combustion
turbine capacity operates on heavy atmospheric gas oil (HAGO) with the exception of the John
Brown unit, which operates on No. 1 diesel fuel. The full load, net plant heat rates for the
combustion turbine units range from a low of 6,638 Btu/kWh for North Pole 1X1 combined cycle
plant, to 14,587 Btu/kWh for Zehnder 2. GVEA also owns and operates two 2.8 MW diesel
generators used for peaking and black start situations.

4.2.2 Existing Energy Resources Used
Briefly discuss your understanding of the existing energy resources. Include a brief discussion of
any impact the project may have on existing energy infrastructure and resources.
The interaction of net plant heat rate and fuel cost generally determine the dispatch order on a
utility system. Following the principles of economic dispatch, the North Pole CT units are
operated at a higher capacity factor than the Zehnder units or John Brown. GVEA combustion
turbine operation is also economically dispatched against the availability of economy power sales
from Chugach Electric or Anchorage Municipal Light & Power over the AH Intertie. Healy 1 has
a full load, net plant heat rate estimated to be 13,596 Btu/kWh, although its low fuel cost results in
a base load dispatch of the facility during the year. GVEA also purchases 100% of the output as
base load from the Aurora Energy coal plant located in Fairbanks. Under the operatin g agreement
for Bradley Lake, Chugach Electric dispatches the hydro facility but GVEA is afforded scheduling
flexibility and is able to largely use the Bradley Lake energy in a peak shaving mode where it has
the greatest value.
The GVEA system also includes a unique battery energy storage system (BESS),
completed in 2003. The BESS system is an energy storage facility that allows GVEA to utilize up
to 46 MW of stored power for a five-minute period or 27 MW for approximately 15 minutes. The
facility is located in a large warehouse in Fairbanks and consists of nearly 14,000 liquid
electrolyte-filled cells. The facility serves as an electrical bridge, allowing GVEA sufficient time
to bring other generation on-line without shedding load during an unexpected power supply
disruption.
The principal value of a wind project in the GVEA system is to displace higher electric
energy resources. The energy from the proposed Eva Creek Project will be used to off-set
combustion turbine energy. Reducing emissions from fossil fuels with a renewable resource is a
major benefit of the project. The reduction in emissions will be from reduced oil consumption by
GVEA’s combustion turbine. Wind power will not be able to eliminate all CT energy as some
level of CT generation will be required to provide regulation due to the variability of wind. An
additional goal of this project is to reduce the cost of power to the rate payer. Regulation costs in
order to integrate a large scale wind project such as EVA Creek into the GVEA system may be
expensive due to the weak nature of the interconnected Railbelt grid. The reduction in capital
costs to the rate GVEA’s rate base through a grant will improve the cost benefit to the rate payer.
4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
GVEA sells over 1.4 billion kWhrs of electricity a year. The majority of this energy comes from
burning fossil fuel as discussed previously. Energy sales are split evenly among residential,
commercial and industrial loads. This project will reduce the amount of fossil fuel burned by
GVEA to generate electric energy with a secondary goal of also reducing the overall cost of power
to all ratepayers.

4.3 Proposed System
Include information necessary to describe the system you are intending to develop and address
potential system design, land ownership, permits, and environmental issues.
4.3.1 System Design
Provide the following information for the proposed renewable energy system:
A description of renewable energy technology specific to project location
Optimum installed capacity
Anticipated capacity factor
Anticipated annual generation
Anticipated barriers
Basic integration concept
Delivery methods
The Eva Creek Wind project is proposed to have a capacity of 24 MW. The estimated capacity
factor for this project is 36.2% (gross) and 32.6% (net), resulting in an annual energy generation of
68.5 GWh.
Anticipated barriers include the high capital cost (on the order of $4000/kW) and potential
permitting issues as discussed in Section 4.3.3.
Basic integration concept – the project will operate intermittently depending on wind resource to
displace the cost of otherwise operating less economical hydrocarbon fuel combustion turbines.
However, the intermittent nature of the wind resource will necessitate system regulation requirements
and associated costs of implementation. Cost of regulation includes the cost of always maintaining the
ability to pick up or drop generation on fast-reacting combustion turbines. The cost of regulation may
vary significantly depending on factors such as wind variability, system load, available system
resources, fuel costs, etc
Delivery methods – energy will be generated and delivered into the existing GVEA system.
4.3.2 Land Ownership
Identify potential land ownership issues, including whether site owners have agreed to the project or
how you intend to approach land ownership and access issues.
The land identified for the GVEA Eva Creek wind generation farm is currently owned by the following
agencies and entities.
State of Alaska, Department of Natural Resources (DNR)
State of Alaska, DOT
University of Alaska
Private Land Owners
Unpatented State Mining Claims
Mental Health Trust Land
Alaska Railroad Corporation
The State of Alaska, DNR, is the largest land owner in the area. GVEA has met with DNR on a

preliminary basis and they are supportive of this project. No formal land use or permit applicati ons
have been submitted.
There is an existing 100-foot wide access road (Ferry Road/Eva Creek Road). Portions of the
existing road will serve well as is and other portions will need to be upgraded or widened to
accommodate trucks transporting equipment to the site. GVEA will work with the State of Alaska DNR
and DOT on the road use and any necessary changes to the existing road. The Alaska Railroad will be
the access point to the project and will be involved in material staging.
The other land owners have not been contacted at this point.
4.3.3 Permits
Provide the following information as it may relate to permitting and how you intend to address
outstanding permit issues.
List of applicable permits
Anticipated permitting timeline
Identify and discussion of potential barriers
The GVEA staff has identified a number of permits required before we can proceed with the project.
Listed below are the areas and the Government Agencies involved:

Potential barriers include:
Historically, the biggest detraction of wind energy projects from an environmental standpoint is the
effect on avian mortality. Much of this detraction has been remedied through the design and use of
turbine blades that spin slower. Depending on the location of the project, noise can also be an issue.
Critics of wind energy projects have raised concerns that the noise emitted from operation of a wind
turbine constitutes a nuisance or harms wildlife. Some states have enacted statutes prescribing
allowable noise levels that must be met by a project.
Other environmental concerns with the permitting of wind projects involve wildlife issues where a
project may disturb wildlife habitat. In addition, because the development of a site often requires
grading and construction, erosion issues and the effect of the construction on habitats and riparian
zones may have to be addressed.
It is anticipated that permitting will take at least one year and is scheduled for completion in
2010.
Renewable Energy Fund
Grant Application
AEA 09-004 Grant Application Page 24 of 77 9/2/2008
Ferry Road will require substantial realignment and grading, taking improvements outside the
100 foot right-of-way, it is unknown at this time whether there will be opposition to this re-
alignment. Two years ago GVEA held an informal meeting in the community which was well
attended to discuss the potential project. Ferry is a community of approximately 20 households.
In addition, there are a number of seasonal cabins located in the area.
As with all Wind projects, the avian interaction will be closely looked at; however, the US Fish
and Wildlife has expressed support for renewable energy projects and their willingness to work
with GVEA. GVEA conducted an extensive avian study which included this area as part of the
Northern Intertie project.
4.3.4 Environmental
Address whether the following environmental and land use issues apply, and if so how they will be
addressed:
Threatened or Endangered species
Habitat issues
Wetlands and other protected areas
Archaeological and historical resources
Land development constraints
Telecommunications interference
Aviation considerations
Visual, aesthetics impacts
Identify and discuss other potential barriers
Any potential issues and mitigating measures with respect to the following will be identified during the
agency review and public comment period through the State permit process.
Threatened or endangered species – unlikely in this area based on the work conducted for the
Northern Intertie project.
Habitat issues – little impact to wildlife habitat, hunting activities may be slightly impacted, but
we have had some discussions with local residents and don’t believe access will be limited.
Wetlands and other protected areas – no protected areas but some areas of ridge top wetlands
will require an individual permit.
Archaeological and historical resources – Surveys have been done at the current met
(meteorological) sites and no significant findings have been found. Individual WTG tower sites
will be examined.
Land development constraints – dependant on public comment and DNR stipulations.
Telecommunications interference – Area is outside of microwave and cell corridors, no
interference is expected.
Aviation considerations – The area does not affect commercial traffic, but is in an area between
Fairbanks and Healy, subject to both private and military low flying aircraft. Based on public
and FAA comments, measures may be taken to mitigate.
Visual, aesthetics impacts – area falls about 12 miles east of the transportation corridor and may
be visible along ridge tops. Public comment will be taken as part of the permitting process.
Avian study - Area has previously been identified as a major Sandhill Crane migration route and will
require further study to mitigate any impacts.

Potential power purchase/sales price - at a minimum indicate a price range
Proposed rate of return from grant-funded project
The GVEA membership recommitted in 2006 to having its electric cooperative own its own power
generation for the long term. This means GVEA would use the grant to build and own the Eva Creek
Wind Project installation and add it to its mix of energy sources for electric power generation. While
wind will have its challenges, all studies conducted over the last six years tell us it can reduce fuel costs
for GVEA, which benefits the GVEA membership. We avoid negotiating a purchase of wind power at
a price the market will bear, which currently could be around 14 cents kWh. All capital costs born by
GVEA will roll into GVEA’s basic tariff rate and will be recovered over the life of the project. The
significant financial return to GVEA’s members is the reduction to fuel and purchase power costs.

4.4.5 Business Plan
Discuss your plan for operating the completed project so that it will be sustainable.
Include at a minimum proposed business structure(s) and concepts that may be
considered.
A Business Plan for Golden Valley Electric Association (GVEA) was prepared to support
its potential 24 MW Eva Creek Wind project. This business plan is attached in full.
The business plan assumes that GVEA will develop and own the project, with equity
capitalization at its average cost of capital at 6%. The Eva Creek Wind project is assumed
to benefit from a Renewable Energy Fund Grant (REFG), which is assumed to offset 85%
of project capital costs. The electricity produced by the wind project will offset some
portion of the production requirements of GVEA’s remaining resources.
The capital cost of the project would be approximately $93 million. The business plan
has assumed a year 2012 operation start-up for the project.
The attached business plan indicates that the cost of production of energy will be
approximately $42/MWh including the cost of capital recovery of the GVEA-funded 15%
of capital costs. An additional cost of system regulation will be incurred due to the
variable, intermittent nature of wind energy generation. The business plan assumes this
cost to be on the order of $50/MWh.

United States and Canada. Most of the wind projects SEM has supported have been in the
Americas and Europe.
SEM believes the wind capacity studies indicate cost savings for GVEA long-term as it
pilots the use of wind as a key component to the energy mix that will be so important in
Alaska’s future.

SECTION 5– PROJECT BENEFIT
Explain the economic and public benefits of your project. Include direct cost
savings, and how the people of Alaska will benefit from the project.
The benefits information should include the following:
Potential annual fuel displacement (gal and $) over the lifetime of the evaluated
renewable energy project
Anticipated annual revenue (based on i.e. a Proposed Power Purchase
Agreement price, RCA tariff, or avoided cost of ownership)
Potential additional annual incentives (i.e. tax credits)
Potential additional annual revenue streams (i.e. green tag sales or other
renewable energy subsidies or programs that might be available)
Discuss the non-economic public benefits to Alaskans over the lifetime of the
project
Potential annual fuel displacement (gal and $) over the lifetime of the evaluated
renewable energy project:
Potential fuel savings will be dependant on what power is displaced by the wind energy.
GVEA’s NPP GT 1 & 2 use 4,989,546 gallons of HAGO to produce 68,515MWhrs for an
annual savings of $14,469,683. NPEP uses 4,226,501 gallons of naphtha to produce
68,515MWhrs for an annual savings of $11,647,550. GVEA’s members will save
between $233 and $289 million dollars over the 20 year life of the project based on
current fuel prices. Essentially fuel savings will be somewhere between 85 to 100 million
gallons.
Potential additional annual incentives:
There may be additional future savings to GVEA when carbon tax legislation is
developed. The savings will be dependent on the tax rate and fuel source offset by the
wind energy.
Discuss the non-economic public benefits to Alaskans over the lifetime of the
project:
Wind is increasingly seen as an important renewable energy source to harness to
mitigate the negative impacts of fossil based fuels. Although in some instances aesthetics
of windmills has caused community issues and turbine design initially affected avian
populations, the improvements in design and careful consideration of location provide a
relatively quiet and a clean source of power.
Nationwide electric customers are supporting their utilities efforts in developing
renewable energy; and GVEA has had an active Green Power committee which helped
shape the board’s renewable energy strategy for the cooperative. GVEA met 2007 board
goals of its Green Power Pledge to use 10% of the 2007 peak system load (223 MW) with
renewable sources and has committed to meet a 20% goal by 2014. GVEA takes pride in
being responsive to its membership when it can incorporate new ideas without excessive
cost to its membership.

GVEA is in the unique position of having six years of reliable data on the feasibility of
Eva Creek as a site for what is likely to be the United States’ largest Arctic wind
generation project.
In addition to the benefit of reducing our carbon footprint through the integration of
renewable energy sources into our system and the benefit of reduced costs to our
members, there are other benefits to the state of Alaska as a whole.
For example, with the investment in this infrastructure and the lessons learned from
completion of this first major Arctic wind generation project in America, GVEA
contributes to the understanding of the challenges of such construction in northern
climates. Any future installation should be easier because of this “model” project. Of
special significance to Alaska, is the capability to expand the system at Eva Creek to
provide additional renewable energy to Railbelt Utilities at a cost far less than the initial
investment. The Eva Creek site can accommodate expansion; it will have already been
permitted and early operation will work out and resolve any unanticipated issues.
Another benefit is the ability of the Interior and Fairbanks to build an image of a clean
energy destination which has had an impact elsewhere on attracting conventions, travelers,
new residents and businesses to an area.
Finally, this project will develop a skilled workforce to operate and maintain wind
generation systems.
SECTION 6 – GRANT BUDGET
Tell us how much your total project costs. Include any investments to date and funding
sources, how much is requested in grant funds, and additional investments you will
make as an applicant.
Include an estimate of budget costs by tasks using the form - GrantBudget.xls
Funding sources include GVEA’s financial commitment to the project. For the past
decade GVEA, in response to its members, has invested in wind studies to assess the
feasibility of going forward with a major development to capture wind capacity at Eva
Creek near Ferry, AK.
Investments to Date and funding sources – GVEA has spent $1,000,000 of the
Association’s general funds to advance the Eva Creek Wind Project to the existing level
of development. In 2002, GVEA funded a terrain to high level wind data predictive wind
resource evaluation which was then field proofed by a meteorologist who sited two areas
for further evaluation. These two areas were Murphy Dome in Fairbanks and Eva Creek
near Ferry, Alaska.
In addition, GVEA began evaluating the potential cost benefit of wind in the GVEA
system. In 2003 land permits were obtained and a data collection site (met site) was
installed in the Eva Creek area. The met site was maintained; data was downloads and
evaluated in 2004. The results suggested Eva Creek was a favorable wind resource
warranting further investigation.
In 2005 land permits were obtained, an archeological study undertaken and an
additional 5 met sites were installed in the area, the existing site was maintained, and data
was evaluated. In 2006 resource evaluation continued and the environmental permitting
process was defined. A Feasibility Study was completed suggesting wind had the

potential of reducing fuel costs for GVEA members. In 2007 and 2008 a System
Integration Study was undertaken in two separate phases to identify how a wind project
would be integrated into the GVEA system, the met sites were maintained and data
downloaded and evaluated.
Note. There were four additional Eva Creek met sites added and one at Walker Dome as
a resource comparison and repeater to link all the sites to the GVEA microwave
communications backbone.

Executive Summary
Sterling Energy Management, LLC (SEM) has prepared a Business Plan for Golden
Valley Electric Association (GVEA) to support its potential 24 MW Eva Creek Wind
project. The site is located on the east side of the Nenana River near Ferry, Alaska, in
the GVEA service territory in the Interior. The area could support up to 150 MW of wind
generation but GVEA would like to start by installing a 16-turbine 24 MW wind farm.
The business plan assumes that GVEA will develop and own the project at its average
cost of capital at 6%. The Eva Creek Wind project is assumed to benefit from a
Renewable Energy Fund Grant (REFG), which is assumed to offset 85% of project
capital costs. The electricity produced by the wind project will offset some portion of the
production requirements of GVEA’s remaining resources.
The capital cost of the project would be approximately $93 million. SEM has assumed a
year 2012 operation start-up for the project.
The following chart illustrates the results of the preliminary operating and financial
analysis effort.

from other GVEA energy production resources (as shown in the chart above). The
comparison indicates that the Eva Creek Wind energy production displaces more
expensive variable operating cost resources.

Introduction
Sterling Energy Management, LLC (SEM) has completed this initial business plan for the
Eva Creek 24 MW Wind Project for Golden Valley Electric Association (GVEA). SEM
uses the term “initial” to indicate that current assumptions related to site meteorology,
project capital cost, and project operating parameters will require refinement with project
development.
GVEA’s Eva Creek site is approximately 7 miles east of Ferry and near Healy. This site
was selected over the alternate Murphy Dome site because of its more promising energy
production and transmission access. The project size was selected at 24 MW as
appropriate for GVEA’s approximate 250 MW system. Project size is subject to
refinement based on further analysis of system integration and demand characteristics.
The Eva Creek Wind project is expected to take approximately 33 months from inception
to completion assuming there are no delays in permitting. Assuming a decision to
proceed to the development phase is made by early 2010, project completion could be
anticipated in 2012. For purposes of illustrating the project development schedule, tasks
and milestones, we have used September, 2012 as a target operational date.
This business plan assumes that GVEA, as owner of Eva Creek, is not a Federal tax
paying entity and thus cannot realize the benefits of the Federal Production Tax Credits
for wind.
The business plan assumes operations of 16 GE 1.5 MW wind turbine generators with
77 meter rotors. GVEA solicited and received a budgetary proposal for such equipment
from GE. While the business plan currently assumes the GE equipment placement,
GVEA will continue to solicit proposals from all credible manufacturers of wind turbines
during the development effort. Issues such as delivery, performance, cold weather
options, etc. will be considered. GVEA will make an appropriate selection of wind
turbines based on these factors.
SEM developed a preliminary layout for the Eva Creek Wind project as illustrated on the
following diagram.

Capital Costs
Wind turbine supply is the single largest capital cost for the Eva Creek Wind project. Currently,
wind turbine costs have risen based on the Euro/$ exchange rate, escalation in steel prices, and
an overheated sellers market. Cited below is a summary capital cost estimate for the project
using a specific WTG budgetary quote for GE 1.5 MW 77 meter rotor wind turbine generators.

Wind Resource and Energy Production
GVEA commenced its wind energy field measurement program in July 2003, at which time two
30-m meteorological towers (#101, 102) were installed at Murphy Dome. A 30-m tower (#202)
was installed at Eva Creek in August 2004. GVEA then added five towers in the Eva Creek are
during early 2007 to support active wind farm planning at that site. GVEA now has nearly 5
years of data from Murphy Dome and 4 years from Eva Creek.
From this data, a wind study was prepared by Richard Simon, Jeff Gawrych and David Matson
of V-Bar, LLC, on September 28, 2008.
The resulting long-term mean annual wind speed estimates in meters per second, along with
extrapolations to the 80-m hub height:

The aggregate long-term mean annual hub-height wind speed is predicted to be 7.47 mps, and
the aggregate long-term mean annual gross capacity factor is predicted to be 36.21%.
After assuming an allowance of 10% for electrical, availability and other losses (as listed below),
the net capacity factor is assumed to be 32.6%.

An indirect cost of integrating the project into the GVEA resource mix occurs due to the
requirement of regulating the existing GVEA operations to accommodate the uncertain nature of
the wind resource. Cost of regulation includes the cost of always maintaining the ability to pick
up or drop generation on fast-reacting combustion turbines. The cost of regulation may vary
significantly depending on factors such as wind variability, system load, available system
resources, fuel costs, etc. The chart below illustrates an example of regulation cost over a wide
range of load swings:

Operating and Financial Results
SEM prepared a preliminary operating and financial model for the Eva Creek Wind project given
the aforementioned development schedule, capital costs, and operating costs. The model is
transmitted with this assessment document.

A GVEA developed, owned, and operated facility results in a 2009 cost of power estimated at
$31MWh escalating annually at 2.5% in order to meet a 6.0% weighted average cost of capital
target. Inclusion of the cost of regulation (at $50/MWh) increases the cost of the wind energy to
$81/MWh.
The value of the Eva Creek Wind project in the GVEA system is to displace higher electric
energy resources. GVEA currently has sufficient capacity to serve peak loads; however, the
existing resources consume high-cost hydrocarbon fuels. The Eva Creek Wind project would
provide low-cost, non-polluting renewable energy. Based on information in the GVEA
Integrated Resource Plan, SEM made a cursory assessment of the results of this effort
compared to projected variable operating costs (fuel + variable maintenance) for North Pole 1/2
and the new combined cycle unit also located at North Pole. The chart that follows indicates the
results of this assessment.

Appendix A: Generic Wind Project Development Discussion
It is important for this analysis to provide some generic background on the various activities that
result in a successful wind project development. This discussion is based on an approach by an
independent wind project developer. Not all of these activities are applicable to the GVEA
situation. And some activities may be omitted. However, it is a very useful background piece
and check list for applicability to the GVEA situation.
In the early stages of finding a project location many companies have a general approach to
wind energy exploration. The works can be broken down to pre-development, development,
construction, commissioning and project operation. Each of these stages involves unique
activities, and each company will choose when to incorporate these items into the project based
on the specifics of the situation.
For purposes of this analysis, it is useful to generally describe the activities as pre-development
and development phases of a wind energy project.
Pre-Development
The pre-development phase generally involves the following activities:
Companies generally start with evaluating several areas in a state or a region which may
include several states.
Preliminary evaluations are conducted that include location analysis, interviews with
landowners or area locals, consultants, and others to narrow the opportunities for best
potential results and those which fit the company profile and goals.
Preliminary wind resource indications are a basic step in these evaluations to determine the
most energetic wind sites.
Land availability and general topography of the area which is deemed most suited for the
companies plans are evaluated
Electrical interconnect and transmission access are evaluated to take the projects electrical
generation.
Environmental and social impacts are considered.
Governmental regulations are considered that may improve or impair the project
development. Availability of economic incentives that may improve project economics is
investigated.
Power generation requirements for the region are considered. The potential development
area is evaluated for potential power purchase agreements.
Once all of the preliminary findings above are assessed, the total project development is
economically evaluated.
If the analysis suggests a promising project, agreements are developed with land owners to
install meteorological towers with wind speed data acquisition equipment to assess the strength
of the wind resource. The wind resource data is gathered and analysis is initiated. In some
cases, land lease and/or purchase options for the required land for a project are also executed.
In this pre-development process many preliminary concepts are discussed and general ideas
are conceptualized for a project. Many more projects are conceptualized than are ever moved
to the development stage.

Development
The development stage is where companies have assessed the pre-development analysis to
form a general profile of the project and determine whether the area will be pursued for specific
development. This stage of development is often initiated six to eighteen months after the actual
installation of the first meteorological tower. Companies have a pretty good idea of the
approximate size of the project in terms of “installed capacity” and the company structure to
support the venture.
Many companies follow a development profile which includes the following:
Meteorologists provide services to process the raw data into projected energy yields
based on different turbine sizes and various power performance yields as represented
by various manufacturers of different wind turbines.
Based on the detailed results of an area having adequate wind resource, project
developers become increasingly active in the pursuit of securing the property in the area
of meteorological tower location. Negotiations are initiated with landowners to secure
long term leases with terms that allow the landowner to receive royalties, or the land is
purchased depending on the economics of the situation.
The anticipated social impacts are viewed and the project structure is developed to
promote positive attributes for the local area.
Environmental evaluations begin in the project area (as defined by land leases or
purchases) to determine suitability and compliance with all environmental requirements.
Permitting requirements are defined with local, state and federal entities and all required
governmental processes are incorporated into the project area plan.
Any positive governmental supports like production tax credits, local county incentives or
others are incorporated into preliminary financial models as part of the overall project
economic evaluation.
Detailed analysis on the electrical distribution system are performed, contact and
negotiations for interconnection contract begin with local utilities.
Power purchase agreement potentials are defined and negotiations are carried out to
procure a contract.
Financial support requirements and funding availability for the project are defined and
potential sources are sought to fund the project. Project funding is highly dependent on
the financial strength of the developer and therefore, this activity is unique to each
situation. Some projects are internally funded by large developers and others are
funded by seeking equity investors and project lenders.
Engineering studies are performed for preliminary roads and pad design, grading
requirements, electrical distributions systems, communication systems, buildings, sub
stations, and electrical interconnections.
Industry support contractors and equipment suppliers are engaged to support cost
estimates for the project financial projections in an effort for the developer to determine
more accurate potential project costs and revenue returns. This includes a host of
product suppliers which include vendors who supply electrical cable and equipment, sub
stations, transformers, buildings to house equipment to name just a few. The analysis
for product purchase will include items like:
Best fit product for the project
Pricing for equipment, exchange rate, shipping costs
Product size both production rating and overall dimensions
Performance profile
Project climate and influence to equipment for rating specifications
Topography and constraint for equipment deliveries or installation
Manufacturer delivery schedule and guaranties
Installation provisions

Many companies are funding this effort internally up to this point. The development team is
aligned with the project goals for annual energy production and annualized revenue
requirements. In general a comprehensive plan is in place to begin the final development of the
project when all the project development processes are merging into a real project prior to the
notice to proceed for the construction phase.
It is important to note that at this stage it is often six to ten months prior to actual construction
start due to long lead order items, and lengthy turbine supply agreement negotiations.
Developers commonly look at the following to be sure all details of the project are ready for a
notice to proceed:
Much effort is devoted to selection of the wind turbine supplier for the project. In
general, the wind turbine generator supply costs are Check Numbers against Model of
total direct project costs. Wind turbine generator performance and cost is a major issue
for consideration as it is essential to realizing the electrical generation goals of the
project. Wind turbine generator selection is generally based on cost, power curve (wind
energy capture at various wind speeds), warranties, guarantees, reliability, supplier
performance history, delivery schedules and financial capability. In general, a process of
requesting proposals, evaluating proposal for lowest lifecycle cost, and terms and
conditions lead to selection of a WTG supplier. Upon selection, negotiations are
conducted to finalize a detailed supply agreement.
The power purchase agreement with the project electrical energy customer is finalized.
In this case a power delivery offset assumption and rate base determine the value of the
energy for the GVEA project.
Manufacturers and material providers that have a track record of successfully delivering
on commitments and reliability or track record of equipment performance are selected.
All cost proposals have been received and evaluated for award of contracts or purchase
orders.
Detailed equipment supply agreements with, engineered equipment specifications,
warranties, liabilities, delivery schedules and terms are put in place. Primary among
these is the wind turbine generator supply agreement discussed earlier.
Installation agreements and guaranties on the installation requirements for the
equipment.
Operation and maintenance agreements are developed and finalized.
Material sub suppliers are selected in support of the equipment purchase and
installation, like transport haulers, construction products and materials, etc.
Final negotiations and contracts with contractors are put in place
Final design criteria for the project are established and engineering plans for the project
are completed.
Complete utility service and interconnection agreements are negotiated.
Community outreach programs are defined, scheduled and open issues resolved.
Final environmental reports and mitigation measures put into place as required.
Project layout and design including final production energy yields are finalized.
Project lender negotiations and funding are completed, if applicable.
All permitting requirements are completed.

Governmental agencies are pursued with an out reach team to address and satisfy their
requirements.
Meteorologist studies and projections for the project performance with the selected wind
turbine generator are completed.
FAA requirements for obstacles are addressed.
Communication systems on the project addressing any radar, and/or military concerns
are defined, specified and designed.
Budgets and schedules are finalized.
Project defined goals are finalized, project development efforts are concluded and a
notice to proceed for construction is issued.
As these project activities reach final negotiations, contractual agreements are put into place.
The industry as a whole requires well defined contracts. Wind projects often with only one wind
turbine exceed a million dollars in total costs. These projects have high dollars involved and
require well defined contracts and agreements. When these agreements are crafted they
include items like the following:
Terms and conditions are well defined so both parties have a clear understanding of
performance criteria, expiration of agreements, the goals and objectives, budgets,
schedules, and limits of liability. All partner authority is well defined with limits of
exposure defined in financial terms for both parties.
Legal and binding contracts that have appropriate legal review and management
authorization. Start dates, end dates, and limits of liabilities are well defined.
Warranties and guaranties of the parties are well defined and corporate limits are
defined both in exposure and in maximum limits the company can cover.
Clear pricing terms and payment schedules are established.
Complete scope of works to define the deliverables for each party and the
consequences of the agreement when commitments are not satisfied.
Terms in the wind turbine supply agreement require negotiation with the selected
provider like:
Product Operating Parameters
Power production characteristics
Electrical Grid Connection Characteristics
Design Life Warranties
Liabilities
Well Defined Deliverables
Prior failures
Size and weights
Constructability
