Lambton Generating Station



Ontario Power Generation’s (OPG) Lambton Generating Station (GS) is located on the St. Clair River, in St. Clair Township, 26 kilometres south of Sarnia, Ontario. Its two operating electricity generating units are capable of producing 950 megawatts (MW) of power. Historically, 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. More recently, due to economic downturn, new electricity supply and emission regulations, Lambton GS’s role has changed to providing reliability during peak demand times and back up electricity generation when other sources are not available.

Lambton GS employs about 300 people from the surrounding community. Their skills and experience are essential to safe and reliable operation. As a team, Lambton GS employees strive to maintain a safe environment that is respectful, supportive and committed to performance excellence.

Over the past 20 years, Lambton GS invested over $500 million in the installation of flue gas desulphurization (FGD) and selective catalytic reduction (SCR) equipment to improve the plant’s environmental performance.

Looking to the future, Ontario’s Long-Term Energy Plan, announced by the Minister of Energy in November 2010, recognized that converting Lambton GS generators to natural gas is an option for the future, if needed for system reliability. Co-firing of natural gas and biomass may be considered in the future for OPG stations which are first repowered to natural gas.
