OPG’s operations in southwest Ontario involve some of the largest and most historic hydroelectric stations in the province. Most notably, the Sir Adam Beck I Generating Station (GS) has been producing clean, renewable power since Dec. 28, 1921, when the station’s first unit was commissioned.
The Sir Adam Beck II GS and the Sir Adam Beck Pump Generating Station are also located on the lower Niagara River. Water for all three of these stations is supplied through three underground tunnels and one canal. OPG also operates two smaller hydroelectric stations, DeCew I GS and DeCew II GS, in St. Catharines with water drawn from Lake Gibson and Lake Moodie via the Welland Canal.
The combined annual production of the five hydroelectric stations in southwest Ontario is approximately 12 billion kilowatt-hours. This is enough electricity to power more than one million homes year-round. These stations have a total capacity of 2,278 megawatts and are managed by a full-time staff complement of over 200 employees.
OPG has a long tradition of giving back to the communities in which we operate. Each year we contribute to more than 100 not-for-profit initiatives in Niagara Falls, Niagara-On-the-Lake, St. Catharines, and Welland.
