Sundance Power Station is a coal fired station owned by TransAlta Corp., located 70 km west of Edmonton, Alberta, Canada on Lake Wabamun. It comprised six units (two 280 MW units and four larger units); both 280 MW units were taken out of service in mid-December 2010 and determined to be beyond economic repair. A legal battle between the owner of the PPA (TransCanada) ensued, which forced the two units to come back on line after replacement of the two boiler units.
