Capacity: 10 MW

"Green Energy" CHP Steam Power Plant Uses Alternative Methane-based Natural Gas Biofuels Like Biogas & Landfill Gas Also Burns Natural Gas Gas Fired Power Generation of 10 Megawatts (MW)

This biogas cogen plant is the largest of the smaller scale combined heat and power systems IPP has available for sale.  This 10 megawatt (10,200 kw) thermal power station uses Rankine cycle process to produce energy that could supply electricity to ~2,000 - 6,000 residential customers* and includes:

• Deltak gas fired boiler - burns landfill, bio-gas, methane & natural gas

• steam powered turbine

• 10 MW electric power generator by Ideal Electric Co.

• Complete control room

• Complete documentation available including manuals, drawings, inspection and operational data reports

• Estimate based on average annual electricity consumption figures published by the US Energy Information Administration with a peak load factor of 2.0.

Built in 1996-1998, this steam power plant started operating in 1998. The previous use was for combined heat and power generation from biogas feed sourced from a landfill.  The prior owner shut this chp plant down when its bio gas supply increased dramatically and it decided to replace the gas based power plant with a larger capacity landfill gas power plant.
