Neoen has been awarded a 400MW battery energy storage system (BESS) project in Canada.
The four-hour capacity contract was secured in a competitive tender initiated by the Independent Electricity System Operator (IESO), Ontario’s electric grid operator.
Grey Owl storage will provide the IESO with additional capacity for 20 years, from commissioning, that will contribute to meet the province’s growing energy needs.
The battery will be able to charge during off-peak hours and redistribute the stored energy back into the grid at peak times, when it is needed most.
With a total capacity of 400MW/1600MWh, Grey Owl Storage will be located near the town of Arran-Elderslie, in Bruce County.
The battery is set to be operational by early 2028.
In line with its business model, Neoen, through its subsidiary Shift Solar, will be the long-term owner and operator of the battery.
Neoen Americas’ chief executive Emmanuel Pujol said: “We are thrilled to have been awarded this major contract with the IESO.
“The province’s energy and capacity needs are massive, and Neoen’s ambition is to be a key contributor, by developing a broad portfolio of renewable energy and storage projects for the years to come.
“This is an important step for Neoen in Ontario and Canada, where we are accelerating our development.”
