1970-1979

• The first four units of the Pickering nuclear power station are completed between 1971-1973. Ontario adds its four Bruce units by 1980.
• Two 100 mw submarine cables were completed in 1976 joining PEI to the North American Power grid.
• The first two units of Churchill Falls Hydro-Electric Generating Station achieve full power in 1971. When all 11 units (475,000 kW each) are completed by 1974, Churchill Falls becomes the largest hydroelectric installation of its kind in the world. La Grande-2 in Québec's James Bay project assumes that title in 1979, but loses it later when capacity is subsequently added to Churchill Falls.
• Nuclear production increases throughout the seventies, accounting for more than 4 per cent by mid-decade, and about 10 per cent by the end of the decade.
