Festival Hydro Battery Energy Storage Facility
13,000 sq. ft.
The Festival Hydro Battery Storage Project (Energy Storage System) is contracted with the Ontario Independent Electricity System Operator (IESO) as part of IESO’s long-term energy plan to provide key ancillary services including reactive support, voltage control, and peaking power to the grid through energy storage technologies.
With a usable capacity of 40.8MWh, it is the largest utility connected battery energy storage project in Canada. It included 300 Powin Energy Stack140 systems housed inside a newly constructed, purpose-built warehouse and connected to inverters from Eaton. EllisDon broke ground on the building in mid-July, with work on the battery array beginning in late August. Final connection and commissioning was completed in February 2018.
