Application Cost Worksheet
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. To be determined in this reconnaissance phase of
project.
Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel)
2. Existing Energy Generation
a) Basic configuration (if system is part of the Railbelt1 grid, leave this section blank)
* NPRHA currently gets all of our dock and harbor power from the local village utilities. For
instance in Tatitlek, the electric rate is .76 a kwh, we are only looking to replace a small portion
of the local power , that which supplies the dock and harbor power because of the unique power
usage pattern, we believe that a wind system can be incorporated with a reasonable payback
period. We have estimated the information based on a combined usage fro both villages and
average savings and usages.
i. Number of generators/boilers/other 3 in Tatitlek, 3 in Chenega Bay
ii. Rated capacity of generators/boilers/other Varies in each community combination of 150 and
125 KW Gensets
iii. Generator/boilers/other type Diesel
iv. Age of generators/boilers/other Varies – some rebuilt 5 years ago, some 2 years
ago
v. Efficiency of generators/boilers/other To be determined in this reconnaissance
phase of project. Reflected in the current
$.76kwh rate.
b) Annual O&M cost (if system is part of the Railbelt grid, leave this section blank)
i. Annual O&M cost for labor To be determined in this reconnaissance phase of
project. Reflected in the current $.76kwh rate.
ii. Annual O&M cost for non-labor To be determined in this reconnaissance phase of
project. Reflected in the current $.76kwh rate.
c) Annual electricity production and fuel usage (fill in as applicable) (if system is part of the
Railbelt grid, leave this section blank)
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.

i. Electricity [kWh] Approx 20,000 kwh consumption
ii. Fuel usage
Diesel [gal] 2050 gallons
Other Approx 200 gallons for transport fuel 10 %
iii. Peak Load 6.8kwh at dock
iv. Average Load 1.2 kwh
v. Minimum Load .75 kwh
vi. Efficiency High pressure sodium high mast lighting
vii. Future trends Project a 6% increase in both traffic (lighting needs and rate increases
annually)
d) Annual heating fuel usage (fill in as applicable)
i. Diesel [gal or MMBtu] N/A
ii. Electricity [kWh] N/A
iii. Propane [gal or MMBtu] N/A
iv. Coal [tons or MMBtu] N/A
v. Wood [cords, green tons, dry tons] N/A
vi. Other N/A
3. Proposed System Design
a) Installed capacity 5 kw wind generator at both Tatitlek and Chenega Bay
b) Annual renewable electricity generation
i. Diesel [gal or MMBtu] Approx 2050 gallon saved by 2020
ii. Electricity [kWh]
iii. Propane [gal or MMBtu]
iv. Coal [tons or MMBtu]
v. Wood [cords, green tons, dry tons]
vi. Other
4. Project Cost
a) Total capital cost of new system $211,000
b) Development cost $313,000
c) Annual O&M cost of new system To be determined by final system design
d) Annual fuel cost
5. Project Benefits

RFA AEA 09-004 Application Cost Worksheet revised 9/26/08 Page 3
a) Amount of fuel displaced for
i. Electricity 38,200 gallons over 20 years
ii. Heat N/A but some excess may be used for the mariculture building
iii. Transportation 3820 gallons over 20 years
b) Price of displaced fuel $353,267.00
c) Other economic benefits To be determined during the reconnaissance phase.
one primary benefit will be the ability to kept the public
ferry terminal and oil spill response dock operation and
available for emergency response
d) Amount of Alaska public benefits $40,000 above cost
6. Power Purchase/Sales Price
a) Price for power purchase/sale N/A
7. Project Analysis
a) Basic Economic Analysis
Project benefit/cost ratio Low ratio 1.066 on our lowest project for 20 years and highest costs,
capital costs to mid-range savings = 1.67, capital costs to high-range
savings = 2.40
Payback Total high cost payback lowest increased in other energy costs
projection 18.75 years, capital cost for midrange saving = 11.94 years,
and capital costs to high savings = 8.325 years
