Sundance

The first of six coal-fired generating units at Sundance was commissioned in 1970, and the sixth and final generating unit was commissioned in 1980. The plant is located 70 kilometres west of Edmonton, Alberta, on the south shore of Wabamun Lake.

As a leader in clean electricity, TransAlta is actively working to convert the fuel source for three of the six Sundance units from coal to natural gas, allowing the plant to provide Albertans with clean, reliable and affordable electricity. Sundance Units 1, 2 and 3 have been retired permanently.
