Site C Dam Approved By BC Government

Site C Dam Approved By BC Government

Premier Christy Clark just announced that the Site C Clean Energy Project was approved by the BC Government.

The estimated cost for the project is $8.8 billion and the proposed opening date for the dam would be 2020.

Christy Clark says that the Site C dam will be “affordable, reliable, clean electricity [that] is the backbone of British Columbia’s economy”. She goes on to say “Site C will support our quality of life for decades to come and will enable continued investment and a growing economy.”

Energy Minister Bill Bennett says that the electricity rates in British Columbia is the 3rd lowest in North America and the 4th lowest for industrial and commercial users.

He also said that the dam is needed with the population of BC expected to grow by over one million people and the demand of electricity to go up by as much as 40% over the next 20 years.

He says the advantage of hydroelectric energy is that it is relatively clean compared to natural gas and coal and no one knows what the cost of coal or natural gas will be in 20 years.

Project Overview

Reservoir FootprintsThe BC Hydro Site C Clean Energy dam will be built in the Peace River in northeast BC. It has the capacity of 1,100 megawatts (MW), and will produce around 5,100 gigawatt hours (GWh) of electricity every year.  That is enough energy to power around 450,000 homes per year in BC.

As this would be the 3rd project on one river system, the Site C dam would be significantly more efficient because it will be able to take advantage of the water already stored in the Williston Reservoir. This means the Site C dam will produce 35% of the energy the W.A.C. Bennett Dam produces with only using 5% of the reservoir area.

 Key Components Of Site C Project

  • Accommodation for workers at the dam site, with other worker accommodations offsite nearby in the region
  • Protection of the Hudson’s Hope shoreline
  • A generation station with six 183 MW generating units
  • A temporary construction access bridge across the Peace River at the dam site, access roads in the vicinity
  • Earthfill dam, roughly 1050 meters long and 60 meters high above the riverbed
  • Two brand new 500 kilovolt AC transmission lines to connect the Site C facility to the existing Peace Canyon Substation
  • Realignment of up to 6 segments of Highway 29 over the distance of 30kms
  • 83 km long reservoir that would be on average 2-3 times the width of the current river

Construction Start Date

Initially construction was scheduled to start in January 2015, however the construction has now been delayed to summer to allow more time to finish getting the permits.
