Lambton Generating Station



OPG’s Lambton Generating Station is located on the St. Clair River, in St. Clair Township, 26 kilometres south of Sarnia, Ontario. Built with four generating units, the station’s annual electricity production has been as high as 12 billion kilowatt-hours (kWh) – enough to supply about 1 million homes for a year.

In October 2010, half of the station’s electricity generating units were retired. Today, Lambton GS is capable of producing a total of 950 megawatts (MW) of power.

In January 2013, Ontario announced that the Lambton and Nanticoke coal plants will stop burning coal by the end of 2013. The Independent Electricity System Operator agrees that these units are no longer needed to ensure a reliable supply of electricity to the Province of Ontario for the foreseeable future.

Ontario’s Long-Term Energy Plan, however, does recognize that conversion of some units to natural gas is an option for the long-term future, if needed for system reliability. Co-firing of natural gas and biomass may also be considered.
