Technical FAQs 4

Does Ottawa have a battery energy storage plan?

In 2025, the City of Ottawa established official plan and zoning provisions for battery energy storage uses in accordance with new Official Plan policy. BESS is an emerging technology using batteries and associated equipment to store excess energy from the electrical grid, which can then discharge energy in periods of high demand.

Is a 250-megawatt battery storage project in Ottawa down?

This post has been updated with a comment from Evolugen’s Geoff Wright. A proposed 250-megawatt battery storage project in Ottawa’s rural west is down but not out, after the city’s Agriculture and Rural Affairs Committee (ARAC) voted unanimously last week to reject the plan.

Will a Dunrobin battery energy storage system give Ottawa Free Money?

(Credit: ASHLEY FRASER) For the majority of Ottawa’s city councillors, approving the Dunrobin battery energy storage system (BESS) was a no-brainer. Battery storage makes variable wind and solar power more practical. Sounds good. Allowing the project means that the battery company will give the city free money, even better.

Who approves energy storage systems in Ontario?

The primary authority for the Installation and Approval of Energy Storage Systems connected to the electrical grid in Ontario is the Electrical Safety Authority (ESA). The ESA administers Part VIII of the Electricity Act and oversees the Ontario Electrical Safety Code (OESC).
