Please note that some fields might not be applicable for all technologies or all project
phases. Level of information detail varies according to phase requirements.
1. Renewable Energy Source
The Applicant should demonstrate that the renewable energy resource is available on a
sustainable basis.
Annual average resource availability. Class 5 and 6 Wind Resource – Banner Ridge,
Nome Alaska. 18 Turbine Wind Farm, Entegrity
Wind Turbine EW50:
1.17 MW Max Capacity with production of
2,936,000 kWh annual production estimate from
wind farm array including array losses which
represents a 29% capacity factor on the maximum
output capability of the turbine.
This is based on actual data analysis and actual
array layout design modeled for the site and
location from the Snake River Anemometer
installed by AEA.
Turbine Availability Assumed 95%, production
estimation 2,789,200 = 27% Capacity Factor
(NOTE: Entegrity is achieving 98% availability on
turbines with full O&M Package as WCE is
providing that are maintained properly)
(Also, this does not take into account the expected
substantial increased output for air density in the
coastal arctic location)
OUTPUT IS DEPENDENT ON WIND SPEED
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)

Future Needs – Budget Increases with Fleet Age,
These are high O&M Estimates but these turbines
will be in high production and require maintenance:
Years 1-5: $0 Actual Cost, Covered by Western
Community Energy and Entegrity Completely.
Budget Retained annually for O&M account in future
years: $75k per year minimum – Target of $90,000
per year (Approx $0.03 per kWh).
Years 6-10: Beginning Balance in O&M Account.
Assume O&M Budget continues with contribution of
$90K per year as O&M and component
(blade/brakes/etc.) replacement/upgrade funds in
later years. (Approx $0.03 per kWh)
Years 10-20: Assume $0.04 per kWh budgeted for
future increased O&M and upgrades.
Years 20+: Assume $0.05 per kWh budgeted as part
of new contract at that date or other arrangements.
d) Annual fuel cost $0
5. Project Benefits
Renewable Energy Fund
RFA AEA 09-004 Application Cost Worksheet Banner Wind Project Page 4
a) Amount of fuel displaced for
i. Electricity Up to 200,000 gallons of diesel fuel annually (expected range from 175,000
to 209,000 gallons per year from production estimations and actual utility
value of 15.81 kwh per gallon.)
ii. Heat None
iii. Transportation None
b) Price of displaced fuel At $ 3.72 per Gal. (actual last purchase price) *
200,000 gallons = $744,000 one year of savings based
on last actual purchase
c) Other economic benefits Local Jobs for Project Construction: (3 major local
(Anchorage) consultants contracts for project design
phase) (major local contractor (Anchorage) for
construction activities) (4 local contracts (Nome
Companies)for trucking, loading, tower assembly,
electrical) (construction jobs up to 30 Full Time people
at once for several weeks on site)
Revenue for local energy production stays in local
economy instead of leaving local economy to imported
fuel. Project helps lower energy price for residents.
Profits from project are distributed to many local
residents who are then more able to pay their energy
costs. Percentage of profits dedicated to other village
renewable energy projects.
O&M Employment (1+ ongoing technicians) Local
O&M presence creates lasting employment in a highly
skilled new technology job opportunity.
Expansion of Projects to Other Villages (more local
technicians, more local benefits in region) (more diesel
fuel savings in region) (more project reliability in
villages based on Nome O&M centralized support)
d) Amount of Alaska public benefits Creation of Nome Renewable Energy Technician
Training Center – Training Facility to Provide Skilled
People for New Job Opportunities and Growth of Wind
Industry.
Reduced cost of energy to local businesses at critical
time – increases local economy and encourages
growth vs. increased energy costs depress economy
and discourage even staying in business in rural
locations.
Increased sustainability for decreased dependence on
imported diesel fuel for energy production. Less risk of
running out of energy “when the tank is low” with more
locally installed wind generation.

6. Power Purchase/Sales Price
a) Price for power purchase/sale Depends on the outcome of the grant, approximately
$0.09 per kWh with full grant funding and
approximately $0.21 without. Estimated avoided cost
calculation is at $0.23 per kWh minimum.
Base Project Cash Requirements for Capital
Contribution (approx $1.1M) Return on Investment:
$0.05 per kWh, Land Lease: $0.01 per kWh, and O&M
at $0.03 per kWh work out to minimum Energy Sales
rate of $0.09 per kWh if the Grant is fully funded to
keep the Owner’s investment at $1.1M Total.
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio The first benefit this project provides to the community is a departure
from the 100% dependency on imported fuels from outside of Alaska.
Though the State of Alaska benefits from the sale of Oil as an export.
The villages are dependent on imported fuel from outside the state as
their only source of energy. The first step towards a sustainable future
requires a project like this that reaches out and is implemented for the
sake of the future of the community.
This AEA Renewable Energy Fund Grant provides to the Ratepayers
and Community a direct savings on their energy rate of $0.12 per kWh
for every kWh produced and sold to the Utility. Instead of selling the
energy at $0.21 (which is still below the avoided cost) the project will
sell the energy at $0.09. With a target expectation of 3,000,000 kWh
per year (at $0.12 per kwh discount) that represents a direct savings to
the community of $360,000 per year while still providing a reasonable
return on the substantial local investment of over $1M in the project.
This savings will continue year after year for 20 years in the community
and provide a meaningful percentage of energy that is produced
locally. Over a 20 year period that savings amounts to $7,200,000 in
the community for a direct benefit. Thus the benefit cost ratio for the
grant is $7.2M over a cost of $4.126M which equals: 1.74.
If the savings were to be calculated based on the last actual purchase
of Diesel Fuel and that price was assumed constant for 20 years they
would be calculated at $744,000 per year or a total of $14.880M and
the benefit cost ratio would be over 3.6. If the cost of diesel continued
to escalate, that ratio would do the same.
Payback The payback for the grant to the direct benefit to the community on
energy sales price alone is LESS THAN 11.5 YEARS
(5.5 years using the diesel savings of $744k per year for current price)
