RURAL BIO-REFINERY CONCEPT BIOGAS ANAEROBIC DIGESTER NODE - ELECTRICAL OFF-GRID MICRO CHP ECONOMICS BIOGAS/NATURAL GAS POWERED Cost Savings Potential Based on Current Costs Current Ontario Utility Costs: Electricity (all-in) = $0.105 per kWh (Ontario Prices) Nat. Gas (all-in) = $0.10 per M 3 (Ontario Prices) Co-generation OUTPUT - 10Kw Unit for 1 year: Electricity = 12 kW x 8,760H = 105,120 kWh = $11,037.00 Hot Water = 20.2 kW x 8,760H = 176,600 kWh = 17,063 M 3 = $1,706.00 ANNUAL OUTPUT = $12,743.00 for 1 year Customer Savings Potential: Cost of 12 kWh Co-Gen Machine(s) (@ $1500 per kWh) = $18,000 Costs - Engineering, Marketing, Installation & Taxes = $12,000 Installed Customer’s Cost of a 10kWh Machine = $30,000 Customer’s Lease Cost of 10 kWh Machine (5 years @ 4%) = $ 6,614/yr Net Customer Savings ($9,493 – $6,614 = $2,880) = $ 2,880/yr Capital Cost Tax Adjustments (5yrsX 20 % @ 30%) = $ 1,800/yr Annual Gain during 1 st five years = $ 4,680/yr Annual Gain > 5 years = $ 9,493/yr Source: Aisin World Corporation of America, Sterling Energy Cost of Natural Gas to run 10 kW CHP for 1 year: Natural Gas consumption = 38kW x 8,760H = 332,880 kWh = 32,500 M 3 = $3,250.00 for 1 year Savings in Utilities Costs for 1 year: Operating Savings = $12,743- $3,250 ECONOMICS OF MICRO CHP DEPENDS ON FINDING A USE FOR THE HOT WATER. THE FEED IN TARIFF CURRENTLY ALLOWS CHP USERS TO IGNORE USES FOR HOT WATER, (i.e.) CROP DRYING, BUILDING HEATING ETC. Net Operating Savings = $ 9,493.00 for 1 year (Not including; Capital Cost Recovery up to 50% per year for companies)
