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. 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, 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 On railbelt, NA. ii. Rated capacity of generators/boilers/other iii. Generator/boilers/other type iv. Age of generators/boilers/other v. Efficiency of generators/boilers/other 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] ii.

Project Cost a) Total capital cost of new system $14,700,000 b) Development cost $ 2,000,000 c) Annual O&M cost of new system $ 300,000 d) Annual fuel cost $0 5. Project Benefits a) Amount of fuel displaced for i. Electricity 21,700,000 kWh/year ii. Heat NA iii. Transportation NA b) Current price of displaced fuel $0.09 per kWh Per 2011 AEA forecasts for southern railbelt c) Other economic benefits Included in future fuel cost projections d) Alaska public benefits $42,000,000 (per AEA model) 6. Power Purchase/Sales Price a) Price for power purchase/sale AEA 2011 model for southern railbelt. ($0.09 per kWh in 2014) 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio With 50 year life, $42M / $13.2M = 3.18 Payback (years) $16.7M / $2.0 M = 8.4 years
