Description

The Power Station consists of one 170 MW gas turbine, supplied by General Electric, that in a combined cycle configuration also generates steam for a steam turbine, resulting in a combined total of 265 MW. The plant uses both natural gas and landfill gas. In addition to power generation, the Thorold Plant includes two Natural Gas/Waste Gas fired boilers which will provide necessary steam to the paper mill when the Gas Turbine is not in service.^[4]
