Alectra Energy Solutions and Convergent Energy and Power have completed three Ontario battery projects totalling 80 MW and 320 MWh, the province and the companies said on Nov. 6.
Two of the lithium-ion sites are in Vaughan: Vaughan 3 provides 40 MW and 160 MWh at 27.6 kV, and Vaughan 1E adds 20 MW and 80 MWh at the same voltage. The third, Arlen, sits in Guelph with 20 MW and 80 MWh at 13.8 kV. Each can discharge for four hours at full output. Ontario said the units entered service on time and on budget but disclosed no cost, and neither release names a battery supplier or a commercial operation date.
The projects won 20-year contracts with the Independent Electricity System Operator in 2023 under the Expedited Long-Term 1 procurement. Their weighted price of C$1,116.50 per MW-business day sits 27% above the C$881.09 average for storage in that round, which allocated 881.7 MW.
Ontario had 228 MW of storage three years ago, mostly at a single pumped-hydro plant, and has since contracted nearly 3,000 MW of batteries. A follow-up long-term round secured 1,784 MW, part of 2,194.91 MW of new capacity due between 2026 and 2028.
Energy minister Stephen Lecce said the batteries return low-cost off-peak nuclear output to the grid at peak. The system operator expects provincial demand could rise by as much as 90% by 2050.
