SNC-Lavalin, M. Sullivan & Son to lead $100M hydro dam redevelopment

Calabogie Generating Station

One of Canada’s most prominent engineering firms is partnering with an eastern Ontario construction company on a $100-million project to build a new hydroelectric power plant on the Madawaska River.

SNC-Lavalin said Monday it is part of a joint venture with Arnprior-based M. Sullivan & Son to decommission the existing powerhouse at Ontario Power Generation’s Calabogie Generating Station, perform excavation work and construct a new facility capable of generating enough electricity to power 10,000 homes.

“The redevelopment of OPG's Calabogie Generating Station will see SNC-Lavalin apply its experience and best of class hydro expertise into one of OPG's oldest and storied generating stations," Sébastien Mousseau, vice-president of power grid and industrial solutions at SNC-Lavalin, said in a statement. 

“Our combined effort with M. Sullivan & Son continues a successful power project partnership that OPG can count on to deliver a first-class modern outcome for a generating station with a century of history.”

The redevelopment project, expected to be completed in 2022, will double the station’s generating capacity from five to 10 megawatts. Originally constructed in 1917, the Calabogie Generating Station was already nearing the end of its operational life span when it suffered extensive damage in the tornado that swept through the Ottawa-Gatineau region in September 2018.
