Level of information detail varies according to phase requirements. 1. Renewable Energy Source – Bethel Wind Project, Bethel, Alaska The Applicant should demonstrate that the renewable energy resource is available on a sustainable basis. Annual average resource availability. Class 4 wind resource available (best in wintertime when electrical demand is highest). 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) i. Number of generators/boilers/other 6 ii. Rated capacity of generators/boilers/other 2,220 kW each or 13.320 MW total iii. Generator/boilers/other type Diesel, Reciprocating iv. Age of generators/boilers/other Unknown, but fairly old v. Efficiency of generators/boilers/other Unknown, but likely fairly low. 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 ii. Annual O&M cost for non-labor N/A 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] 40 million MWh per year ii. Fuel usage Diesel [gal] unknown Other iii. Peak Load 8 MW iv. Average Load 5 MW v. Minimum Load 3 MW vi. Efficiency N/A vii. Future trends None known. d) Annual heating fuel usage (fill in as applicable) i. Diesel [gal or MMBtu] N/A 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. Renewable Energy Fund RFA AEA 09-004 Application Cost Worksheet revised 9/26/08 Page 2 ii. Electricity [kWh] iii. Propane [gal or MMBtu] iv. Coal [tons or MMBtu] v. Wood [cords, green tons, dry tons] vi. Other 3. Proposed System Design a) Installed capacity 2 MW or more, depending on the ability to sell power to the utility grid. b) Annual renewable electricity generation i. Diesel [gal or MMBtu] ii. Electricity [kWh] 5.3 million kWh for 2 MW of nameplate capacity. 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 $8.7 million b) Development cost $100,000 c) Annual O&M cost of new system Estimate about three cents per kW hour produced and sold (plus the cost of project financing). d) Annual fuel cost Zero, nada, zip. 5. Project Benefits a) Amount of fuel displaced for i. Electricity At assumed efficiencies for diesels, about 400,000 gallons annually. ii. Heat iii. Transportation b) Price of displaced fuel Liquid hydrocarbons – Price varies, but in 2008 the price was approximately 25 cents per kWh. c) Other economic benefits Reduced air pollution in Bethel region. d) Amount of Alaska public benefits If we save BUC and consumers just five cent per kWh over the price of generating electricity using liquid Renewable Energy Fund RFA AEA 09-004 Application Cost Worksheet revised 9/26/08 Page 3 hydrocarbons: 2 MW Wind Farm X 30 percent Capacity Factor X 8,760 hours per year = about 5.3 million kW hours per year or about $263,000 per year in savings, or about $5.3 million over 20 years. 6. Power Purchase/Sales Price a) Price for power purchase/sale Close to BUC’s actual avoided cost. 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio This project will assist in making energy in this region more affordable, as well as reduce air pollution and greenhouse gas emissions, and help make the US more energy self sufficient, reducing our balance of payments problems. Payback Projected project commissioning is projected for fall 2009, provided permitting can be completed in a timely manner this fall/winter.
