Lac Seul/Ear Falls - Obishikokaang Waasiganikewigamig Generating Station (29.3 MW) - Ear Falls: English River

Commercial Operation on February 18, 2009

Obishikokaang Waasiganikewigamig/Lac Seul Generating Station (GS) achieved commercial operation February 18, 2009.

OPG and the Lac Seul First Nation have formed a historic partnership that will see the First Nation own 25 per cent of the station. The station has dual names. The Ojibway name, Obishikokaang Waasiganikewigamig, means “White Pine Narrows electricity generating building”. White Pine Narrows is the original Ojibway name for the area where the station is located. The English name of the plant is Lac Seul GS.

The Lac Seul GS is located adjacent to Ontario Power Generation’s (OPG) existing Ear Falls GS on the English River in Ear Falls. The facilities are located at the outlet of the Lac Seul reservoir on the English River in northwest Ontario, in the Town of Ear Falls which is approximately 100 km north of Dryden. This new station consists of one 12.5 MW double regulated pit turbine and will operate under a rated net head of 9.78 metres and flow of 139.45 cubic metre per second. It will use the excess water flow that has historically been passed by the existing Ear Falls GS. This water will now be used to generate clean, renewable energy.

The combined nameplate capacity of the two facilities is 29.3 MW. The existing 4-unit Ear Falls GS was placed in service between 1930 and 1948. Each unit has two intakes. The Ear Falls GS powerhouse is connected to the 185-metre long Lac Seul Conservation Dam which is owned by the Province of Ontario and operated by OPG. The dam is used to regulate water levels and flows for the purposes of power production in Ontario and Manitoba.

It is estimated these facilities will generate approximately 185,000 megawatt-hours of renewable energy per year.
