Overview

The $900 million Waneta Expansion Project will see the addition of a second powerhouse located immediately downstream of the Waneta Dam on the Pend d’Oreille River. The expansion will share the existing hydraulic head and generate power from water that would otherwise be spilled. Output from the new powerhouse will be stepped-up to 230 kV and delivered to BC Hydro’s Selkirk Substation through a new 10 km transmission line. The expansion will produce clean, renewable, cost effective, power for all British Columbians.

During construction the owners meet monthly with a Community Impact Management Committee (CIMC), consisting of local residents, members of local and regional government, first nations, and the contractors. These stakeholders provide ongoing support to encourage positive community impacts and benefits and relay community concerns resulting from construction of the project. The CIMC oversees an independent socio-economic monitor who produces reports available to the public.

The project is committed to a high standard of quality, safety and environmental stewardship.

Columbia Power is managing the construction of this project on behalf of the owners. Fortis Inc. 51%, Columbia Power 32.5% and Columbia Basin Trust 16.5%.
