Hydro-Quebec is urging customers to watch their energy consumption to ease strain on the network. As Montrealers woke up to a deep freeze in the region, over 15,000 customers were without power on the island, and there were over a dozen service interruptions in the Côte-des-Neiges--Notre-Dame-de-Grace borough. “We have teams working on this outage and doing their utmost to restore the service as quickly as possible,” said Hydro-Quebec spokesperson Lynn St-Laurent. “People can follow the situation on the Hydro-Quebec website. Clients will see their power restored gradually. The issue is at the Hampstead substation. We have teams that are investigating.” The crown corporation is asking clients to take the following actions during peak consumption times - from 6 a.m. to 10 a.m. and 4 p.m. to 8 p.m.: “In winter, Quebec uses nearly twice as much electricity as it does in summer,” Hydro-Quebec said. “On February 3, 2023, temperatures went as low as −52°C, and power demand hit a historic peak of 43,124 MW.” On Saturday, when Montreal temperatures dropped below -30 C with the wind chill, Quebec consumed 36,176 MW by 12:30 p.m.
