Site C Dam 

The Site C Clean Energy Project in British Columbia is the province’s third dam and hydroelectric generating station. It will provide the region with long-term energy, economic growth and job creation. FlatironDragados, in a joint venture with Aecon and EBC, is building the Generating Stations and Spillways civil works.

The project will generate approximately 5,100 gigawatt-hours of electricity annually — enough to power 450,000 homes or 1.7 million electric vehicles. FlatironDragados constructed mass and reinforced concrete structures for the powerhouse, spillways and penstock encasement from 950,000 cubic meters of concrete.

Key features:

• Earthfill dam approximately 1,050 meters long and 60 meters high
• Generating station with six, 183-megawatt units
• 800-meter roller-compacted-concrete buttress for seismic protection
• 83-kilometer-long reservoir, up to three times the width of the current river
• Two, 500-kilovolt AC transmission lines

Site C will provide reliable, clean power for generations while creating opportunities for local communities and Indigenous Nations through jobs, contracts and infrastructure improvements.
