Level of information detail varies according to phase requirements. 1. Renewable Energy Source – Coal Bed Methane Gas for Communities < 10K This worksheet uses estimated costs for the Kircher CBM Well and Colony High/Middle School Complex CHP System to evaluate the potential positive impact to rural Alaska communities. The Applicant should demonstrate that the renewable energy resource is available on a sustainable basis. Annual average resource availability. 100% - 16,500 MCF/Day 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 Multiple generator sizes and types in many villages throughout Alaska ii. Rated capacity of generators/boilers/other Typical rural system, 200 – 1200 kWh iii. Generator/boilers/other type iv. Age of generators/boilers/other Typical rural system installed 1965 - 1999 (43 yr – 13 yr) v. Efficiency of generators/boilers/other Typical rural system, 30% b) Annual O&M cost (if system is part of the Railbelt grid, leave this section blank) i. Annual O&M cost for labor $.32 cents/ kWh per AVEC (includes non-labor costs) ii. Annual O&M cost for non-labor See above 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] 1,437,000 kWh ii. Fuel usage Diesel [gal] 100,000 – 300,000 gal Other iii. Peak Load iv. Average Load v. Minimum Load vi. Efficiency 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.

Future trends Price of fuel rising rapidly d) Annual heating fuel usage (fill in as applicable) i. Diesel [gal or MMBtu] 108,000 gal (combined electric and heating) ii. Electricity [kWh] iii. Propane [gal or MMBtu] iv. Coal [tons or MMBtu] v. Wood [cords, green tons, dry tons] vi. Other – Natural Gas 3. Proposed System Design a) Installed capacity 10,000 kWh / day, 18 MMBTU / day b) Annual renewable electricity generation i. Diesel [gal or MMBtu] 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 $8.6 Million ( CBM well and CHP plant) b) Development cost $1 Million c) Annual O&M cost of new system $125,000 - $150,000 depending on water or air access to site. d) Annual fuel cost Royalties on CBM production can range from $400- $525K depending on water or air access to site. 5. Project Benefits a) Amount of fuel displaced for i. Electricity 2,680,000 – 3,650,000 kWh / year ii. Heat iii. Transportation b) Price of displaced fuel $600K – 1,100K / year depending on water or air access to site.

Power Purchase/Sales Price a) Price for power purchase/sale $.11 - $.14 / kWh 7. Project Analysis a) Basic Economic Analysis Project benefit/cost ratio 1.5 + Payback Less then 10 years The CBM/CHP Prototype will cost approx $8.6MM per village 15 of the 38 rural communities with CBM potential may result in producible gas saving the State $140,000 per village per year PCE. Residents of rural Alaska could save 40 - 50% of their current energy cost – as much as $10,000 per resident per year.
