St. Mary is a run-of-river hydroelectric facility with installed capacity of two MW, located at the base of the St. Mary Dam on the Waterton Reservoir, near Magrath, in Southern Alberta. This wholly-owned facility utilizes a horizontal double Alstom Francis turbine and a Kato generator. This facility began commercial operations in December 1992. Generation from this facility will be subject to the terms of a TransAlta PPA that terminates in 2033. Management believes that the estimated annual gross generation from the facility will be approximately 16 GWh.
