​Lennox Generating Station


As Canada’s largest oil/gas-fuelled electricity generating station, the Lennox Generating Station is located on the north shore of Lake Ontario, in the Town of Greater Napanee, in eastern Ontario. With a generating capacity of 2,100 megawatts, Lennox GS can produce enough electricity to meet approximately eight per cent of Ontario’s needs. Lennox GS’s role is to provide reliability during peak demand times and back up when other sources are not available.

The oil used at Lennox GS is known as residual oil, which is a by-product left after removing higher value products like gasoline from the refining process. To improve environmental performance and add fuelling flexibility, OPG and Union Gas Limited invested more than $40 million in 1997 to build a 17-kilometre pipeline, and convert the station’s boilers to burn either oil or natural gas. This flexibility helps OPG reduce air emissions, while reducing operating costs by taking advantage of spot market fuel prices.

OPG employees employs about 160 people from the surrounding community to safely and reliably operate the Lennox GS.
