of Hydro Energy
Hydroelectric power is a timeless, renewable resource that has fuelled Ontario's economic growth since the beginning of the twentieth century and today accounts for almost one third of Ontario Power Generation's electricity production. Hydroelectric generation, our lowest-cost power source, produced 32.4 terawatt-hours in 2011.
The historic importance and future potential of hydroelectric power can be attributed to its low production costs, reliability, flexibility to meet both ongoing base electricity needs and peak demands, and its reliance on water - an indigenous, renewable resource.
OPG operates 65 hydroelectric stations, including a green power portfolio of 29 small hydroelectric plants, and 240 dams on 24 river systems. The smallest station has a generating capacity of just one megawatt (MW); the largest more than 1,400 MW.
Because the water we depend on is shared by many users, OPG maintains strong partnerships with governments, local industry, environmental groups, recreational users and other community stakeholders. Our primary partnerships focus on:
Watershed Management: balancing energy production requirements with environmental, commercial and recreational needs within a watershed
Community Connections: nurturing strong relationships with users of the watersheds on which our facilities are located
