Design and Construction of the 45 MW Kokish River Hydroelectric Project in British Columbia, Canada

摘要

This presentation will cover the design innovations and lessons learned from the detailed design and construction of the Kokish River Hydroelectric Project recently constructed in the northern part of Vancouver Island located in British Columbia, Canada. This hydroelectric facility is a private sector development by Kwagis Power, a limited partnership of Brookfield Renewable Energy Group and the ‘Namgis First Nation that was awarded an energy purchase agreement by BC Hydro in an open call for clean energy. The project will generate up to 45 MW of clean renewable energy that will be delivered to the British Columbia electrical grid, with an annual energy production capacity of roughly 140 GWh, enough electricity to power close to 13 000 homes. The Kokish River Hydroelectric project is a ru‐n ‐of river project with a maximum design generation flow of 25 m~3/s and operating head of 238 m. Peter Kiewit Infrastructure Co. was awarded an EPC Contract for the design and construction of the project with Knight Piesold Ltd. appointed the Design Engineer for the project.
