Canadian utility Hydro One reported a surge in electricity distribution volumes during Q2 2026 on Wednesday, with peak demand across its key service region, Ontario, edging higher.
Total electricity distributed during the quarter surged 4.4% year-over-year to 7,550 gigawatt-hours during the three months to June 30, from 7,231 GWh a year earlier. For H1, 2026, electricity distributed rose 4.1% to 17,235 GWh from 16,555 GWh.
Average monthly Ontario 60-minute peak demand increased 0.5% to 20,936 megawatts, from 20,836 MW a year earlier.
The company advanced several transmission projects during the quarter, including the Northeast Power Line, a single-circuit 500-kilovolt transmission line expected to increase transfer capability between northeastern and northwestern Ontario by about 900 MW.
Besides this, it filed applications for the Longwood to Lakeshore Transmission Line, which is expected to bring about 550 MW of electricity to southwestern Ontario and be completed in 2030.
