Marmora Pumped Storage – Clean Energy Hub Project

This closed-loop pumped storage Project does not seem likely to result in any serious negative impacts to other freshwater bodies, nor methylmercury contamination of fish tissue or greenhouse gas emissions, and it will provide clean backup power during the low-flow periods when small run-of-river hydroelectric facilities are shutting down because of reduced stream flow. Comparing the power output of this peak demand storage Project, and its minimal environmental impacts to the number of rivers it would have taken to generate 400 to 500 MW of power from dozens of small hydropower projects, makes it ORA’s preferred choice over conventional hydroelectric facilities.

Water Street Pumphouse – Crowe River

Project:  Water Street Pumphouse – upgrade/expansion – 1.3 MW Installed Capacity
River:  Crowe River
Proponent:  Peterborough Utilities – 41 Water Street, Marmora, ON
Contract:  Hydroelectric Contract Initiative (HCI)

Upgrades under HCI

Pursuant to the January 21, 2013, Ministerial Direction, the OPA is no longer accepting applications for refurbishment, upgrades or expansions of existing facilities currently holding HCI contracts. The OPA in due course may amend the HCI Standard Contract Guidelines to incorporate changes to reflect this direction. The OPA is currently developing the Hydroelectric Standard Offer program (HESOP) for expansion projects as per the June 26, 2013, Ministerial Direction.

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.
