BC Hydro, British Columbia’s province-owned electric company, on March 11 selected 19 renewable projects to be built in the province as part of a request for proposals for renewable projects. The projects include five wind farms and 14 run-of-river hydro projects that will cost a total of about $3 billion. When complete, the projects will produce 2,400 GWh of electricity. BC Hydro is still considering 28 other renewable projects to meet the province’s goal of 5,000 GWh of renewable electricity.
