Renewable Energy Fund Round 4
Project Cost/Benefit Worksheet
RFA AEA11-005 Application Cost Worksheet Page 1 7-21-10
Please note that some fields might not be applicable for all technologies or all project
phases. The 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. 7.78 m/s average wind speed AEA
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
2. Existing Energy Generation and Usage
a) Basic configuration (if system is part of the Railbelt1 grid, leave this section blank)
i. Number of generators/boilers/other 4 gensets, I flywheel, 5 turbines, 3 primary boilers
ii. Rated capacity of generators/boilers/other Diesel 2@ 260kW 1@230kW, 1@122kW, f475kW
wind, 600 thermal kW
iii. Generator/boilers/other type
iv. Age of generators/boilers/other Recent, 2005 – two gensets 2009
v. Efficiency of generators/boilers/other 13.0 kWhr/gal est
b) Annual O&M cost (if system is part of the Railbelt grid, leave this section blank)
i. Annual O&M cost for labor
ii. Annual O&M cost for non-labor
c) Annual electricity production and fuel usage (fill in as applicable) (if system is part of the
Railbelt grid, leave this section blank)
i. Electricity [kWh] 1,019,419
ii. Fuel usage
Diesel [gal] 81,658 gallons
Other
iii. Peak Load 280 kW
iv. Average Load 190 kW
v. Minimum Load 120 kW est
vi. Efficiency
vii. Future trends 1. Typical overall usage of electricity has a growth rate of 2% per year.
2. More importantly, peak and average loads are increasing in large
steps with the addition of new facilities. A new school will open in Kong this
winter. The school will have an average operating power requirement of
65 kW. New airport buildings and runway lighting will be added next spring.
A new clinic, new housing units as well as water and sewer improvements
are planned before 2015. Each of these Infrastructure improvements will
result in increases in both peak and average electrical loads.
d) Annual heating fuel usage (fill in as applicable)
1 The Railbelt grid connects all customers of Chugach Electric Association, Homer Electric Association, Golden Valley Electric
Association, the City of Seward Electric Department, Matanuska Electric Association and Anchorage Municipal Light and Power.
