Plans are underway to revamp one of Ontario Power Generation’s (OPG) oldest hydroelectric generating stations.

Constructed in 1917, the Calabogie Generating Station (GS) has been producing renewable electricity on the Madawaska River for more than 100 years.

OPG is proposing to redevelop the five-megawatt station to extend its operating life. The project would increase Calabogie’s capacity to approximately 10 to 15 MW while reusing existing infrastructure.

​Redeveloping Calabogie GS will improve the available hydroelectric potential at the site, reduce greenhouse gas emissions, and increase the amount of clean, renewable energy available for Ontario.

The proposed redevelopment will involve an environmental assessment process to evaluate the project’s potential effects to the environment during both construction and operation.

“Consultation with Indigenous communities and the public is an integral component of this process,” said Matt MacDonald, director of business development with OPG.

As part of the proposal, which is now in the definition phase, OPG does not plan to alter the current water levels and flows for the station.

For years, Calabogie GS has been a mainstay in eastern Ontario. Originally constructed by the Calabogie Light and Power Company, the station first supported local development and the lumber industry.

OPG’s predecessor, the Hydro-Electric Power Commission of Ontario, acquired Calabogie GS in 1929.
