Island Falls Generating Station

The Island Falls Generating Station is a four-unit hydroelectric station located on the Abitibi River in Tolmie and Menapia Townships. The station was built in 1925, with two of the four units operating at 25 Hz. In 1996, the station was modernized and all units were converted to 60 Hz operation. In 2018 one turbine was replaced and the unit rewound, with a second to be completed soon. The station has an installed capacity of 44.3 MW at a gross head of 19 meters. Located 30 km north of the confluence of the Abitibi and Frederickhouse Rivers, the station is a run-of-river plant. Local storage capability allows a moderate level of peaking performance during all but freshet conditions.
