Strategically located next to the existing Marguerite Lake substation, the first phase comprises 320 MW capacity and up to 48 hours of electricity (15360 MWh). Its primary purpose is to store surplus electricity from the grid by compressing air and storing it in underground salt caverns created through solution mining. During periods of high electricity demand, compressed air will be released to power turbines, providing electricity to the Alberta Interconnected Electric System (AIES). This flexibility effectively addresses fluctuations in electricity demand and facilitates the integration of intermittent renewable energy sources like wind and solar into Alberta's energy mix.
