Alectra Energy Solutions and Convergent Energy and Power announced Nov. 6 that three battery-storage facilities in Ontario were operational, adding 320 megawatt-hours of storage capacity. Two facilities are in Vaughan and one is in Guelph. The completion announcement describes storage installations serving the provincial grid, rather than new power-generation plants.
The largest, Vaughan 3, is a 40-megawatt, 160-megawatt-hour facility on Rutherford Road. Vaughan 1E on Dufferin Street and Arlen Energy Storage on Clair Road West in Guelph each provide 20 megawatts and 80 megawatt-hours. The figures distinguish power capacity from stored energy; the announced 320 megawatt-hours is the combined energy rating.
The partners won three contracts in 2023 through the Independent Electricity System Operator’s Expedited Long-Term 1 procurement. All three facilities now operate under 20-year contracts with the provincial system operator, according to the companies’ announcement. The two Vaughan sites connect at 27.6 kilovolts, while the Guelph facility connects at 13.8 kilovolts.
The batteries store electricity when it is available and release it during high-demand periods, giving the system operator more flexibility to balance supply and demand, the announcement said. Their continuing role under the long-term contracts is to support the Ontario grid. The companies’ reliability statements describe the purpose of the installations, not a separately measured improvement reported by this publication.
