OPG is now producing more, clean, renewable electricity from three new generating units at existing stations in Little Long, Harmon and Kipling. OPG also replaced the existing Smoky Falls facility with a new three-unit station. The stations are located approximately 70 kilometres north of Kapuskasing and 200 kilometres south of Moose Factory.

The project has added 438 megawatts (MW) of new hydro capacity without creating new dams on other rivers. This reduces the environmental impacts that would otherwise be caused by new developments.

Hydro stations typically remain in service for 90 years or more. Hydro electricity is crucial to Ontario's electrical system because it provides renewable energy on demand, when it’s needed most.

First Nation partners

Construction of the $2.6 billion Lower Mattagami Project is complete and site restoration is underway. OPG's partner in the project is the Moose Cree First Nation. The First Nation has a 25 per cent equity share in the new generating units.
