Level of information detail varies according to phase requirements. 1. Renewable Energy Source – Delta Wind Project, Delta River Region, Alaska The Applicant should demonstrate that the renewable energy resource is available on a sustainable basis. Annual average resource availability. Class 6 to 7 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 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. Fuel usage Diesel [gal] Other iii. Peak Load iv. Average Load v. Minimum Load vi. Efficiency vii. Future trends d) Annual heating fuel usage (fill in as applicable) i. Diesel [gal or MMBtu] 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 50 MW b) Annual renewable electricity generation i. Diesel [gal or MMBtu] ii. Electricity [kWh] 131 million kWh for 50 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 $132.3 million b) Development cost $3.6 million c) Annual O&M cost of new system Direct O&M cost is two cents per kW hour produced and sold. d) Annual fuel cost Zero, nada, zip. 5. Project Benefits a) Amount of fuel displaced for i. Electricity At published efficiencies for GVEA’s North Pole turbine, 9.5 million gallons annually (GVEA‘s 2007Annual Report) ii. Heat iii. Transportation b) Price of displaced fuel Liquid hydrocarbons – Price varies, but in 2008 the price was approximately 25 cents per kWh. At an average price of $3.50, this would be approximately $33.25 million in fuel expenditure displacement. c) Other economic benefits 1. Reduced air pollution in Fairbanks/North Pole areas Renewable Energy Fund RFA AEA 09-004 Application Cost Worksheet revised 9/26/08 Page 3 resulting in reduced health care costs. 2. Some of the money that used to flow out of Fairbanks (and Alaska) to buy oil from non-Alaskan companies will now stay in the local area and strengthen our economy. d) Amount of Alaska public benefits If we save GVEA and consumers just one cent per kWh over the price of generating electricity using liquid hydrocarbons: 40 MW Wind Farm X 30 percent Capacity Factor X 8,000 hours per year = about 100 million kW hours per year or $1.3 million per year in savings, or $26.28 million over 20 years. If GVEA line losses from North Pole to Delta are 3%, then our 131 million kW hours per year saves consumers: 131 million kWh X $0.12/ kWh (average cost) X 0.03 (3% loss) = $360,000 per year in savings, or $9.46 million over 20 years. This gives a total savings of $35.74 million over a 20 year wind farm lifespan. 6. Power Purchase/Sales Price a) Price for power purchase/sale Close to GVEA’s actual avoided cost. 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio This grant will allow the project to proceed from the Final Design / Permitting phase through to construction of required infrastructure for building the Delta Wind Project. Payback Projected project commissioning is fall 2010.
