  • 2 water storage dams that don't generate power.
  • 7 smaller hydroelectric dams.

Total capacity: 6,882 MW, about 58% of BC Hydro's total capacity

Total power generated: Each year, facilities in the Columbia Region generate an average of about 21,900 gigawatt-hours (48% of BC Hydro's total of 46,000 GWh).

The Columbia Region provides almost half of BC Hydro's total generating capacity, thanks to large dams that were built as part of the Columbia River Treaty.

BC Hydro's total generating capacity

BC Hydro's total generating capacity is based on the nameplate capacity of each facility.

These numbers are updated annually. Percentages are based on BC Hydro's total generating capacity of 12,048.9 MW which includes hydroelectric, thermal and diesel generating stations owned by BC Hydro.
