The IESO selected Powin Energy to deploy its advanced battery storage technology in a purpose-built facility in Stratford that is the largest battery storage installation in Canada and one of the largest in the world.

Constructed between June and October 2017, the facility provides up to 8.8 MW/ 40.8 MWh of battery backup power to the grid. The installation uses Powin’s Stack140 battery array, a modular and flexible system that provides 140 kW in each battery stack and connects them together under common control using Powin’s exclusive bp-OS battery management software.
