Clean Energy Station to Produce Electricity for Future Generations Adapted from Information by BC Hydro For many years, a cornerstone of British Columbia’s economy and quality of life has been its clean and abundant energy produc- tion. BC Hydro’s Site C Clean Energy Project is a hydroelectric gen- erating station on the Peace River in northeast British Columbia, Canada. It will provide 1100 megawatts (MW) of capacity, and pro- duce an estimated 5100 gigawatt-hours of electricity each year, which would be enough energy to power the equivalent of 450,000 homes. As the third energy project on the Peace River sys- tem, Site C will gain significant efficiencies by utilizing water already stored in the Williston Reservoir. This means Site C will generate approximately 35% of the energy produced at W.A.C. Bennett Dam, with only 5% of the reservoir area. Construction on the project started in 2015, and will be completed in 2024. Once operational, Site C will be a source of clean, reliable, and affordable electricity for more than a century. The project design includes access roads in the vicinity of the site, and a temporary construction access bridge stretching across the Peace River at the dam site. Two temporary cofferdams will allow for construction of the earthfill dam, which will be approximately 3500 feet long and 200 feet high above the riverbed. To con- nect the Site C facilities to the existing Peace Canyon Substation, two new 500-kilovolt AC transmission lines will be installed along an existing right-of-way. A roller-compacted- concrete buttress measuring over 2600 feet will be constructed to enhance seismic pro- tection. The generating station will include six 183-MW generating units. Accompanying the station, a reservoir with a length of over 50 miles with a width on average three times the current river’s will be created. Ongoing construction work has included infrastructure additions on-site and on the access roads. Survey work, including drilling, on the north and south banks of the dam has commenced. Some geotechnical investigations, including geotechnical drilling, test pitting, installation of monitoring equip- ment, and geotechnical support work along the transmission line corridor was completed with more to come. Construction workers completed a drainage tunnel. The continuation of earthworks on the north and south bank, including excavation on the south bank and north bank slope stabilization is expected to continue throughout the year. In 2018, work on the generating station, spillways, substation, and installation of the turbines and generators are expected to begin.
