Technical FAQs 4

What is Ontario battery energy storage?

Ontario Battery Energy Storage anchors IESO strategy, easing peak demand and boosting grid reliability. Projects like Oneida BESS (250MW) and nearly 3GW procurements integrate renewables, wind and solar, enabling flexible, decarbonized power.

Will storage technology help manage peak energy demand in Ontario?

The Ontario Independent Electricity System Operator (IESO) has highlighted that these storage technologies will be crucial for managing peak demand in the coming years. Ontario's energy demands have been on the rise, driven by factors such as population growth, electric vehicle manufacturing, data center expansions, and heavy industrial activity.

Does Toronto Hydro have a battery energy storage system?

Toronto Hydro recently installed a battery energy storage system (BESS) with Renewable Energy Systems Canada and support from the Province of Ontario’s Smart Grid Funds. The Bulwer BESS project is a 2 MW/2 MWh BESS located at the Bulwer Municipal Station (MS), a decommissioned 4.16kV Toronto Hydro electrical substation, located in downtown Toronto.

Why is Ontario investing in battery energy storage systems?

Ontario’s electricity grid is facing increasing demand amid a looming supply crunch, prompting the province to invest heavily in battery energy storage systems (BESS) as a key solution.
