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. Village power scale - Approximately 2 MW for prototype system. 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 Reconnaissance phase – pilot location has not been selected. Will be implemented in village location with diesel or fuel oil generation system. ii. Rated capacity of generators/boilers/other Prototype will be constructed in Palmer 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 TBD 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] 2000 KW (Prototype) ii. Fuel usage Diesel [gal] TBD Other Up to 25% projected efficiency over standard installations iii. Peak Load iv. Average Load v. Minimum Load vi. Efficiency vii. Future trends 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 d) Annual heating fuel usage (fill in as applicable) i. Diesel [gal or MMBtu] Specific to locale ii. Electricity [kWh] iii. Propane [gal or MMBtu] iv. Coal [tons or MMBtu] v. Wood [cords, green tons, dry tons] Specific to locale vi. Other Specific to locale 3. Proposed System Design a) Installed capacity Village power scale - Approximately 2 MW for prototype system. b) Annual renewable electricity generation i. Diesel [gal or MMBtu] Village power scale – will displace diesel fuel used for electric generation and with waste heat recovery for building heat and agricultural operations. 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 The capital cost of the prototype system is anticipated to be in the range of $7 to $10 million dollars (on a $700- 800/square ft basis). b) Development cost Development cost for prototype system is $7.5 to $10.5 million. c) Annual O&M cost of new system Annual O&M costs for the new system the proposal estimates to be slightly more than the existing activity. However, there is a commercial component involved in the proposal that generates added revenue that can offset most if not all of the additional cost, The schedule for O&M will vary by installation but should be consistent with current practice d) Annual fuel cost The proposal assumes that a new system will use less fuel than like systems currently in use. The amount will be determined during the reconnaissance study using current Bush Alaska fuel costs. Renewable Energy Fund RFA AEA 09-004 Application Cost Worksheet revised 9/26/08 Page 3 5. Project Benefits a) Amount of fuel displaced for i. Electricity Approximately 2 MW for prototype system, but will depend on scale of pilot project and village power needs. ii. Heat Waste heat from electricity generation will be used to generate secondary power and to heat agricultural enterprise. iii. Transportation b) Price of displaced fuel Bush Alaska prices - $15.00 per gallon for diesel fuel. c) Other economic benefits Fuel savings and revenue will be estimated during the reconnaissance study. However, the design of the mechanical system will reduce fuel usage in rural communities as well as provides a “renewable energy” source for a secondary income stream with the incorporation of the controlled environment agricultural unit (CEAU). d) Amount of Alaska public benefits The addition of the CEAU will have the ability to provide jobs, an education component, a partial reduction of food costs, and a source of community pride by improved self reliance. 6. Power Purchase/Sales Price a) Price for power purchase/sale To be determined by reconnaissance study. 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio To be determined by reconnaissance study. Payback To be determined by reconnaissance study.
