Kwalsa and Upper Stave Hydroelectric Project

The Kwalsa and Upper Stave Hydroelectric project includes six hydroelectric facilities with a total installed capacity of 150 MW and an interconnecting 138 kV transmission line. Four of the facilities are located in the upper Harrison Lake area and the other two facilities are located in the Upper Stave River area about 50 km north of Mission, British Columbia, Canada.

Knight Piésold's Role

The Owner, Contractor, Douglas First Nation, and Knight Piésold worked closely together to develop the low impact hydroelectric projects overcoming unique challenges while delivering under budget and ahead of schedule.

Knight Piésold initially worked for the former Owner (Cloudworks Energy Inc.) in identifying a number of potential hydroelectric sites for development, and then worked directly for the EPC Contractor, Peter Kiewit Infrastructure Co., regarding all aspects of detailed design as well as construction quality assurance. The power produced by the facilities is integral in helping British Columbia attain its self-sufficiency and clean energy goals.

Since construction completion, Knight Piésold has provided ongoing operational environmental monitoring services to the current Owner (Innergex Renewable Energy Inc.) The monitoring services include the installation and maintenance of telemetry-based hydrometric streamflow gauging stations used to monitor environmental flow compliance, and periodic monitoring of stream channel morphology to assess potential changes in aquatic habitat.

Award

In 2011, the design for the Upper Stave Hydroelectric Project received an Award of Merit from the Consulting Engineers of British Columbia (now the Association of Consulting Engineering Companies British Columbia).
