  • Water will flow inside this spiral case and spin the turbine to generate electricity. | March 2025
  • The Site C generating station at night. | March 2025
  • The Site C dam and generating station, with the approach channel left of centre. | March 2025
  • Ice is receding from the reservoir on the upstream side of the Site C dam. | March 2025
  • The Site C substation near the approach channel and the generating station. | March 2025
  • Water flows from the approach channel, via the intakes, through the penstocks and into the powerhouse. From the powerhouse, electricity passes through the sets of transformers (bottom of photo) and is transmitted to the substation by the lines atop the transmission towers. | March 2025
  • Water from the approach channel flows via the intakes into the six penstocks. The penstocks convey water into the powerhouse to drive the turbines and generators. Electricity is generated at 13.8 kilovolts and stepped up to 500 kilovolts before feeding into the transmission lines visible at the bottom of the photo. After passing through the turbines, all the water flows out of the powerhouse into the Peace River. | March 2025
  • The tailrace is the immediate downstream area where water has exited the powerhouse and/or spillway. When this image was taken, water was flowing through the spillways to balance downstream flows until generating unit 4 went into service. | March 2025
  • Permanent lighting is in place on the downstream face of the dam. | March 2025
  • In use from 2020 to 2024, the temporary upstream fishway is now decommissioned. | March 2025
  • Ventilation installed at the diversion outlet tunnels to prepare for backfilling. | March 2025
  • The transformer yard behind the powerhouse. Water travels from the approach channel into the penstocks at right and down 80 metres to the lower levels of the powerhouse. Water spins the turbines to generate electricity. The power is routed out to the transformers at left and then carried up and over the approach channel on lines supported by the transmission towers above. | March 2025

  • Water is flowing from penstock units 1 and 2 into turbine units 1 and 2. Power is travelling into the BC Hydro electricity grid through the first transmission tower. A third turbine unit came online on February 24. | February 2025
