Oldman River Hydroelectric Plant

The Oldman River Hydroelectric Plant is a 32 megawatt run-of-river plant in southern Alberta and is ATCO Power’s first hydro project. ATCO Power was selected by Alberta Environment and Sustainable Resource Development (AESRD) to develop the project at the existing dam site near Pincher Creek. Power generated by the Oldman River Hydroelectric Plant meets the needs of up to 25,000 households and is sold into the Power Pool of Alberta. The Oldman River Hydroelectric Plant is operated remotely and is jointly owned by ATCO Power (75%) and Piikani First Nation (25%). Generation is provided predominantly between May and September when water flow is greatest. A step-up substation at the power plant increases voltage from 13.8 Kv to 138 kV and connects through a 138 kV transmission line.
