Marmora Pumped Storage – Crowe River

Marmora Generating Station Proposal

The Marmora Pumped Storage power generation proposal is located in Marmora, Ontario, adjacent to the Crowe River.The Marmora project will use an open pit and an upper reservoir in a closed-loop configuration.  Combination pumps/generators will pump water up into the reservoir during off-peak periods and then release it back down into the mine during on-peak periods to generate electricity. The design provides for an average head of 140 meters, producing 400 MW of generated power to enable time-shifting to support renewable energy sources and grid demand patterns.
