Peter Sutherland Sr. Generating Station

Ontario Power Generation and Coral Rapids Power Corporation (a company wholly owned by Taykwa Tagamou Nation) are equity partners in the Peter Sutherland Sr. Generating Station. Named after a respected community elder, the 28 MW hydroelectric power station is remotely located at the confluence of the Abitibi River and New Post Creek within the Taykwa Tagamou Nation traditional territory of northeastern Ontario. A portion of the flows from New Post Creek have been harnessed to provide clean, renewable hydroelectric energy.

KGS Group worked closely with Ontario Power Generation and Coral Rapids Power through the conceptual and preliminary design stages, ultimately acting as the owner’s representative through the design-build construction phase that was performed by Kiewit and Aecon. KGS Group staff were onsite throughout construction assisting and collaborating with the owners and contractor team.

This multi-disciplinary project included:

• powerhouse containing two horizontal axis Francis turbine units with a total plant capacity of 28 MW
• gated intake structure and approach channel
• 4 m diameter steel penstock 250 m long
• 520 m long embankment dam with a cement-bentonite core
• two-bay gated spillway

Construction was completed safely, on budget, and ahead of schedule. The project is not only an investment into Ontario’s clean energy future; it is a symbol of reconciliation and the culmination of a strong partnership between Taykwa Tagamou Nation and Ontario Power Generation that will benefit the community for generations.
