Other Considerations Safety Color Rendering Comfort of Staff, Population

Cogeneration

Micro turbines up to .5MW Usually 65kW increments Natural Gas Fired… Recuperators Capstone

Gas engine .3 to 5MW Diesel or Natural Gas Waukesha, Caterpillar

Turbines 3MW plus Solar – Saturn, Taurus, Mercury, Mars, Titan

Gas Micro-Turbines• Combine energy conservation/efficiencies with on

site production of electricity (co-generation)• Local production and local consumption significantly

reduces transportation and distribution costs• Installation of high efficiency gas microturbines to

produce on-site electricity and reduce GHG emissions

Financial

At $5 per MCF gas $.08 per kWh

Payback may be as little as 3 to 4 years Requires Cogeneration mode 100% heat utilization

Micro-Turbine

200kW Unit Cost = $390,000 ($1950/kW) 8,000 hours 1,600,000 kWh = $128,000 4,143 mmBtu = $20,715 Purchased Gas = 16,480 mmBtu = $82,400 Net Savings = $66,315 Simple Payback = 5.88 years Maintenance = $15,000/year Simple Payback with Maintenance = 7.6 years

Natural Gas / Internal Combustion

375 kW Unit Cost = $588,000 ($1568/kW) 8,000 hours 3,000,000 kWh = $240,000 9,800 mmBtu = $48,999 Purchased Gas = 28,355 mmBtu = $141,776 Net Savings = $147,223 Simple Payback = 3.99 years Annual Maintenance = $28,000 Payback with Maintenance = 4.9

Turbine 4,600 kW Unit Cost = $9,600,000 ($2087/kW) 8,000 hours 36,800,000 kWh = $2,944,000 204,422 mmBtu = $1,022,112 Purchased Gas = 326,158 mmBtu = $1,630,792 Net Savings = $2,335,320 Simple Payback = 4.11 years Annual Maintenance = $345,000 Simple Payback with Maintenance = 4.82 years

Requirements

Long Term Gas Contracts Currently 5 years Expect longer soon Ability to negotiate with Well Driller

Constant Load is Best for Driller Utilizing own natural resource

Heat Load Process Loads Terminal Reheats Domestic Hot Water Swimming Pools Absorbers
