Marguerite Lake Energy Project

The Power of Stored Energy

Ready 24/7

The Marguerite Lake Energy Hub is designed to combine complementary energy storage technologies at one strategically located site — providing rapid response when the grid needs it immediately and sustained energy when it needs it for longer.

CAES Storage Facility: UP TO 640 MW 30,720 MWh

Battery Energy Storage: UP TO 250 MW 500 MWh

Seconds. Hours. Days.

Two complementary technologies. One integrated solution.
