Sundance Power Station is a gas fired station (previously 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.[2] 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. As of Dec 2013 both units had returned to production.

Units 1 and 2 operated under a 100% power purchase agreement with Alberta, known as 'Sundance A'. In August 2000 TransCanada purchased the rights to the production from Sundance A and B.[3] Coal for the station is sourced from the TransAlta Highvale Coal Mine that is adjacent to the power station.
