Bc Hydro says 7,600-megawatt May demand sets record
bc hydro said electricity demand reached roughly 7,600 megawatts this week as a spring heatwave drove up use across B.C., setting a May record for the utility. The spike came early in the month and put more strain on homes and businesses running cooling equipment.
7,600 megawatts in May
7,600 megawatts was the highest level ever seen in May, according to BC Hydro, which said the figure reflected unusually hot weather and higher power use across the province. The utility said much of the increase came from air conditioners and fans, a load that matters most to households trying to keep indoor temperatures manageable during the first heat of the season.
Nearly 70 per cent of all B.C. households now have some form of air conditioning, BC Hydro said, helping explain why demand moved so quickly once temperatures climbed. The utility also linked part of the rise to air purifiers and other devices used during wildfire season, adding another layer to a demand pattern that now goes beyond cooling alone.
Monday peak and Wednesday cool-down
Peak hourly demand – the single hour each day when customers use the most electricity – is expected to have peaked on Monday, BC Hydro said. Higher than usual energy demand was expected to continue until Wednesday, when temperatures were forecast to cool, leaving the system under elevated load for several more days even as the hottest part of the spell passed.
The demand surge was still well below the peak levels typically seen during the coldest winter periods, BC Hydro said, a reminder that this record was seasonal, not system-wide. For customers deciding whether to add more cooling capacity, the utility is also offering limited-time retail rebates from May 1 to Aug. 21, 2026.
Rebates at five retailers
The rebates include $50 off Energy Star window air conditioners and high-efficiency portable units, plus $30 off select Energy Star air purifiers. They are available at Costco, Best Buy, London Drugs, Home Depot and RONA, giving households a short list of stores where the incentive is already on the shelf.
For readers watching their own bills, the immediate takeaway is simple: the early-season heat has already pushed demand to a May record, and BC Hydro is signaling that the pressure should ease only after Wednesday’s cooler temperatures arrive. Until then, the load on the grid is coming from the same devices many households are using to get through the heat.
