Project Description: The East Toba and Montrose Hydroelectric Project is a 235 MW run-of-river green power development located approximately 100 km north of Powell River, British Columbia on the East Toba River and Montrose Creek.

Knight Piésold’s Role: The project was identified and permitted by Knight Piésold for the Owner, Toba Montrose General Partnership.  Knight Piésold was subsequently retained by Peter Kiewit Infrastructure Co. to perform the detailed design of the project under an EPC contract that guaranteed performance, schedule and price. 

Project accomplishments include the design of largest run-of-river project in BC history for the East Toba River facility; design of the largest Coanda Screen installation in the world for the Montrose intake; design of a 150 km 230 kV transmission line through hazardous terrain resulting in robust low impact alignment; and enduring relationships with local communities and three First Nations groups.

Commissioned ahead of schedule, the project is currently delivering green energy to BC Hydro under a long term Energy Purchase Agreement. The project will provide a sustainable and renewable source of energy to British Columbians for generations.

In 2011, the East Toba and Montrose Hydroelectric Project received the Lieutenant Governor’s Award for Engineering Excellence at the Consulting Engineers of British Columbia (CEBC) Awards in Vancouver.
