Ontario Secures 640 MW Battery Storage at Record-Low Cost, June 13

Ontario’s Independent Electricity System Operator announced three battery storage projects totaling 640 megawatts on June 12 through the Long-Term 2 procurement process. The weighted average price is 36% lower than previous battery storage contracts and 16% cheaper than earlier procurements. The projects will power approximately 640,000 homes during peak demand and begin commercial operations by May 1, 2030.

Battery Storage Wins Against All Competitors

In Ontario’s technology-agnostic procurement, battery projects won every contract against gas plants and other alternatives. This follows April results where wind and solar took all 14 generation contracts. The three selected projects include battery storage systems in Greater Napanee, Unincorporated Territory in the District of Kenora, and Norfolk County. Each project has at least 50 percent First Nations equity ownership, ensuring direct economic benefits to local communities.

Cost Savings Drive Grid Reliability

The new battery storage capacity costs 36% less than batteries procured through the government’s earlier E-LT1 procurement and 16% less than the LT1 procurement. Battery energy storage systems store electricity for later use and stabilize the grid when demand spikes. The projects received 20-year contracts and will provide 8-hour battery capacity to support reliability during peak electricity demand periods.

Why Ontario Needs Storage Now

Ontario’s electricity demand is expected to rise significantly as electrification accelerates and industrial demand grows. Battery storage provides flexibility to build an affordable, reliable electricity system. The Canadian Renewable Energy Association praised Ontario’s battery storage leadership, noting that clean technologies demonstrate they will often be the cheapest way to add reliable capacity to a growing grid.

What This Means for Ratepayers

Lower procurement costs directly benefit electricity ratepayers through reduced system costs. The competitive, technology-agnostic process ensures ratepayers receive the lowest-cost power available. Ontario’s results show that battery storage, wind, and solar are now the most cost-effective solutions for grid expansion, making clean energy the economic choice rather than just an environmental one.

Final Thoughts

Ontario’s battery storage procurement demonstrates that clean energy now wins on cost, not just environmental merit. Ratepayers benefit directly from lower electricity system costs as battery storage becomes the cheapest grid reliability solution.
