The level of information detail varies according to phase requirements. 1. Renewable Energy Source: Fourth of July Creek Hydroelectric Project The Applicant should demonstrate that the renewable energy resource is available on a sustainable basis. Annual average resource availability. 120 cfs at 47% availability = 21.7 GWh of net energy output for average water year. Unit depends on project type (e.g. windspeed, hydropower output, biomass 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 N/A – on railbelt ii. Rated capacity of generators/boilers/other N/A – on railbelt iii. Generator/boilers/other type N/A – on railbelt iv. Age of generators/boilers/other N/A – on railbelt v. Efficiency of generators/boilers/other N/A – on railbelt b) Annual O&M cost (if system is part of the Railbelt grid, leave this section blank) i. Annual O&M cost for labor N/A – on railbelt ii. Annual O&M cost for non- labor N/A – on railbelt 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] N/A – on railbelt ii. Fuel usage Diesel [gal] N/A – on railbelt 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.

Project Cost Renewable Energy Fund Round 3 Project Cost/Benefit Worksheet RFA AEA10-015 Application Cost Worksheet Page 3 10-7-09 a) Total capital cost of new system $16,700,000 b) Development cost $ 850,000 c) Annual O&M cost of new system $ 300,000 d) Annual fuel cost Zero 5. Project Benefits a) Amount of fuel displaced for i. Electricity 184,000 MCF of Natural Gas per year ii. Heat N/A iii. Transportation N/A b) Price of displaced fuel $1,676,000 per year (at $9.00 per MCF) c) Other economic benefits $ 280,000 per year d) Amount of Alaska public benefits $0 in quantifiable economic terms 6. Power Purchase/Sales Price a) Price for power purchase/sale $0.071/kWh 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio 50,200,000 / 16,700,000 = 3.01 Payback 16,700,000 / 1,956,000 = 8.5 years
