Canada's largest infrastructure project
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 is being built to help meet B.C.’s long-term electricity needs. It will provide 1,100 megawatts of capacity, and produce about 5,100 gigawatt hours of electricity each year — enough energy to power the equivalent of about 450,000 homes per year.
The Site C project received environmental approvals from the federal and provincial governments in October 2014. In December 2014, the project received approval from the provincial government to proceed to construction.
Main civil works is the largest single contract for construction on the Site C project. It includes:
Construction of the project started in summer 2015 and will be completed in 2024.
Once built, Site C will be a source of clean, reliable and affordable electricity in B.C. for more than 100 years.
In October 2018, PRHP completed the hydroelectric power house foundations (a total volume of 414,000 m3) and also finished the Spillway Apron (122,000 m3).
At peak production of the foundation and spillway work, 9,460 m3 of concrete were poured daily and 160,000 m3 of concrete were poured per month. Significant technical and logistical challenges arose during the project due to the extreme weather conditions. Temperatures fell below -40º during the winter months. Consequently, the concrete placement timelines were restricted to six months to comply with strict temperature control parameters.
In addition, the main civil works contract includes significant ancillary works such as a permanent network of site roads and temporary access bridge, site drainage and debris handling facilities.
On July 8, 2018 members of the RCC team set a new production record at site, placing more than 7,000m3 of roller-compacted concrete (RCC) in a 24-hour period. On July 8, 7,093m3 of RCC was placed in one day, including 1,500m3 using the RCC swinger.
Our previous record of 6,227m3 of RCC placed in a single day was set on September 27, 2017.
