Work underway on OPG’s Calabogie Clean Power project

$100 million investment to boost Eastern Ontario economy

Renfrew – Work is underway on Ontario Power Generation’s (OPG) new Calabogie Generating Station (GS) in eastern Ontario. The new facility, located along the Madawaska River, is expected to be completed by 2022 and will power about 10,000 homes with clean, low-cost renewable electricity.

“We’re excited to rebuild one of our oldest generating stations, especially during these unprecedented times,” said Mike Martelli, OPG’s President of Renewable Generation. “Many options were considered over the years, including retrofitting the existing century-old powerhouse, but a complete redevelopment was determined to be the best option and we’re proud to bring more clean energy to Ontario’s grid.”

“OPG’s operations have been powering Ottawa Valley homes and businesses for decades,” said John Yakabuski, MPP Renfrew-Nipissing-Pembroke. “The men and women who work for OPG are part of our communities, and I’m pleased to see the redevelopment of the Calabogie Generating Station. This project will employ skilled trades from the area and that injection of capital will have a positive impact on people’s lives.”

“We’re excited to rebuild one of our oldest generating stations, especially during these unprecedented times."

Mike Martelli, OPG’s President of Renewable Generation

Constructed in 1917, the five-megawatt (MW) Calabogie Generating Station was extensively damaged by a tornado in 2018. The new facility will replace the original, century-old powerhouse with a new, higher capacity powerhouse that will double its capacity for clean, hydro generation from five to approximately 10 MW. OPG is investing over $100 million to redevelop the site.

Throughout the planning and execution phases, OPG has consulted with Indigenous communities, including the Algonquins of Ontario, Algonquins of Pikwakanagan First Nation, and four Williams Treaties First Nations – Alderville First Nation, Curve Lake First Nation, Hiawatha First Nation and Scugog Island First Nation.

SNC-Lavalin and local partner M. Sullivan & Son Ltd. were awarded the design-build contract.

OPG is the largest electricity generator in the province, providing almost half of the power Ontarians rely on every day. We have been proudly operating in eastern Ontario for over 100 years. Today, we have one thermal facility and 10 hydroelectric generating stations on the St. Lawrence, Ottawa and Madawaska Rivers.

OPG is also one of the most diverse generators in North America, with expertise in nuclear, hydroelectric, biomass, solar and natural gas technologies.
