Canoe Creek Hydroelectric
The Canoe Creek Hydroelectric project is a 5.5 MW run-of-river facility located on Vancouver Island. It is locally owned and operated by the Tla-o-qui-aht First Nation and the Swiftwater Power Corp. The facility was built to help the island become more energy self-sufficient and less reliant on mainland power. The power produced is sold to BC Hydro under a long-term electricity purchase agreement. Our role was to provide project layout, preliminary and final design, and optimization of the intake, penstock and powerhouse.
The steep terrain made design and construction a challenge, as did the facility's location in the Pacific Rim rainforest, where annual precipitation is among the heaviest in the world, particularly in winter months.
Canoe Creek Hydro operates by diverting stream flow into a steel penstock at a high elevation intake. A coanda screen was used at the intake to provide a low maintenance and cost-effective method of excluding fine debris from the diverted flow. The flow is conveyed to the powerhouse along a steel penstock, consisting of both exposed and buried portions. Mechanical couplings were used in lieu of welded joints to reduce installation and construction time. The powerhouse accommodates a single pelton turbine and generator unit.
Canoe Creek Hydro is considered a model for sustainable development and renewable energy. It is EcoLogo™ certified and has received numerous industry awards including:
- Clean Energy Association of British Columbia 2010 Project Excellence Award
- Power Engineering's 2010 Best Renewable/Sustainable Project Honorable Mention
