BC Hydro has filed an application with government regulators, seeking approval to add a fifth turbine-generator that would add 500 MW to 1,980-MW Revelstoke Dam in British Columbia.
BC Hydro filed the application — for a certificate of public convenience and necessity — with the British Columbia Utilities Commission on April 13.
Revelstoke Unit 5 was identified in BC Hydro’s 2006 Integrated Electricity Plan/Long-Term Acquisition Plan. The utility said Unit 5 is needed for system reliability by October 2010.
In March, the utilities commission endorsed spending C$12.5 million (US$11 million) to complete the definition phase of Unit 5.
BC Hydro previously initiated stakeholder approvals. Additionally, in October 2006 it submitted an application to the province’s Environmental Assessment Office.
Following receipt of regulatory approvals, the utility would begin further detailed engineering and contracting. Under one scenario, construction would begin in 2008.
Revelstoke Dam power plant began operating in 1984. It originally was deï¿½signed as a six-unit facility, with installation of Unit 5 and a sixth unit being deferred until additional capacity was needed. The project is located on the Columbia River near the city of Revelstoke.
