Marguerite Lake Compressed Air Energy Storage Project

Federation Group Inc. is proposing the construction, operation and decommissioning of the Marguerite Lake Compressed Air Energy Storage Project, a 320-megawatt power plant located about 16 kilometres north of La Corey, Alberta. As proposed, the project would use electric motor-driven compressors to capture excess electricity generated from the power grid and store it underground as compressed air. During times of low power generation, the compressed air would be withdrawn from storage, heated using natural gas, and routed to turbines to generate electricity. The project would operate for over 30 years.
