The Story

The Kitchener Wilmot Hydro Battery Storage Project is one of the largest battery energy storage projects in Canada, and includes 66 Powin Energy Stack140 systems housed inside six purpose built storage containers and connected to inverters from Schneider. The project 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.

EllisDon broke ground on the building in mid-March 2017, and the system was subsequently revised to a completely new battery storage type in late 2018. New designs began in early 2018, and we achieved substantial completion in late July 2018.

Features

• 2MW peak / 6MWh capacity;
• Allows for flexible energy storage and draws at peak and non-peak times, as it stores energy in a similar manner to a series of cell phone batteries;
• Will relieve demand on Kitchener Wilmont Hydro’s grid system during peak hours; and
• Relying less on the central generating system allows for higher voltage stability.
