The level of information detail varies according to phase requirements. 1. Renewable Energy Source Solar PV The Applicant should demonstrate that the renewable energy resource is available on a sustainable basis. Annual average resource availability. 4.51 kWh/m2/day average for the year gives 61,380 kwh/annually for 11pc. 4kw tracking arrays. 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 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] ii. Electricity [kWh] iii. Propane [gal or MMBtu] iv. Coal [tons 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 Round 3 Project Cost/Benefit Worksheet RFA AEA10-015 Application Cost Worksheet Page 2 10-7-09 v. Wood [cords, green tons, dry tons] vi. Other 3. Proposed System Design Capacity and Fuel Usage (Include any projections for continued use of non-renewable fuels) a) Proposed renewable capacity (Wind, Hydro, Biomass, other) [kWh or MMBtu/hr] Solar PV b) Proposed Annual electricity or heat production (fill in as applicable) i. Electricity [kWh] 61,380 ii. Heat [MMBtu] c) Proposed Annual fuel Usage (fill in as applicable) i. Propane [gal or MMBtu] ii. Coal [tons or MMBtu] iii. Wood [cords, green tons, dry tons] iv. Other 4. Project Cost a) Total capital cost of new system $ 561,887.00 b) Development cost 0 c) Annual O&M cost of new system 0 d) Annual fuel cost 0 5. Project Benefits a) Amount of fuel displaced for i. Electricity 1,534,500 Kwh @ 13.5 Kwh/g diesel, gives 113,667 Gallons of diesel saved ii. Heat iii. Transportation b) Price of displaced fuel @ $ 6.50/G average $ 738,835.50 c) Other economic benefits d) Amount of Alaska public benefits This gives 113,667x 22,38 = 2,543,867 lbs of CO2 not released. Invaluable tool for Energy study for students Proves concept of taking schools of the grid incrementally through work with students. As the cost of Diesel increases the payback will get shorter. Renewable Energy Fund Round 3 Project Cost/Benefit Worksheet RFA AEA10-015 Application Cost Worksheet Page 3 10-7-09 6. Power Purchase/Sales Price a) Price for power purchase $ 0.65/Kwh average (The schools cost of electricity vary due to shipping and distance) Value of 1,534,500 Kwh = $ 997,425.00 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio 1. Based on Diesel displacement 738835.5/561887= 1.31 2. Based on electric power displaced 997425/561887=1.775 Payback 1. 19 years 2. 14 years, This is more accurate for the school as they displace the electricity bought with incoming alternate.
