Frequently Asked Questions

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 metres, producing 400 MW of generated power to enable time-shifting to support renewable energy sources and grid demand patterns.
