A joint venture of SNC-Lavalin and M. Sullivan & Son has been awarded a contract valued at over $100 million by Ontario Power Generation (OPG) for Phase 2 of the Calabogie Generating Station Redevelopment.

The JV scope will be to decommission the existing 5MW powerhouse, excavate the forebay and tailrace in line with the hydraulic model, and construct a new two-unit powerhouse with a capacity of 10.7MW. The award follows the completion of the front-end engineering and design (FEED) phase wherein the JV developed the target cost for the execution phase through a detailed options assessment and finalization of critical designs.

“This award is a recognition of our long-standing expertise in the hydro power industry going back to SNC-Lavalin’s founding. It also strengthens our ongoing commitment to supporting our clients in providing clean power to their customers through sustainable solutions,” said Dale Clarke, Executive Vice-President, Infrastructure Services. “In this instance, with OPG, the redeveloped powerhouse will double the clean power generation capacity at Calabogie without impacting the existing river regime.”

“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,” said Sébastien Mousseau, Vice-President, Power Grid & Industrial Solutions. “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.”

Constructed in 1917, the Calabogie Generating Station produced renewable, low-cost electricity on the Madawaska River. On 21 September 2018, the station was affected by a tornado in the Ottawa-Gatineau region. Prior to this event, the generating station was nearing the end of its operational life.

Work is expected to start this month and will take two years to complete.
