Marmora Clean Energy Hub Project

Northland Power Inc., in partnership with Ontario Power Generation, is proposing the construction and operation of a new pumped storage and hydroelectric generating facility located in the municipality of Marmora and Lake, Ontario. As proposed, the Marmora Clean Energy Hub Project would produce up to 500 megawatts, and operate for 100 years. The open-pit lake from the abandoned Marmoraton iron ore mine would be transformed into the lower reservoir of the facility. The project would include an upper reservoir, tunnels and a powerhouse, a water delivery system, and an underground transmission line. The project would also include a 30-megawatt ground-mount solar facility, which would operate for at least 25 years.
