About Site C

Site C will be a third dam and generating station on the Peace River in northeast B.C. The project will provide 1,100 megawatts of capacity and about 5,100 gigawatt hours of energy each year to the province’s integrated electricity system.

Site C Project Components

The project design for the Site C Clean Energy Project includes the following key components:

  • Access roads in the vicinity of the site and a temporary construction access bridge across the Peace River at the dam site.
  • Construction of two temporary cofferdams across the main river channel to allow for construction of the earthfill dam.
  • Worker accommodation at the dam site, with other workers being housed off site and in the region.
  • The realignment of six segments of Highway 29 over a total distance of 30 kilometres.
  • Shoreline protection at Hudson’s Hope.
  • Two new 500 kilovolt AC transmission lines that will connect the Site C facilities to the existing Peace Canyon Substation, along an existing right-of-way.
  • An 800-metre roller-compacted-concrete buttress to enhance seismic protection.
  • An earthfill dam, approximately 1,050 metres long and 60 metres high above the riverbed.
  • A generating station with six 183 MW generating units.
  • An 83-kilometre-long reservoir that will be, on average, two to three times the width of the current river.
