BC Hydro Peak Electricity Demand reached a record 10,902 megawatts during a cold snap, driven by home heating. Peak hours surged; load shifting and energy conservation can ease strain on the grid and lower bills.
Key Points
Record winter peak of 10,902 MW, set during a cold snap, largely from home heating demand at peak hours.
✅ All-time high load: 10,902 MW between 5 and 6 p.m., Dec. 27.
✅ Cold snap increased home heating demand during peak hours.
✅ Shift laundry and dishwashers off-peak; use programmable thermostats.
BC Hydro says the province set a new record for peak electricity demand on Monday as temperatures hit extreme lows, and Quebec shattered consumption records during similar cold weather.
Between 5 and 6 p.m. on Dec. 27, demand for electricity hit an all-time high of 10,902 megawatts, which is higher than the previous record of 10,577 megawatts set in 2020, and follows a record-breaking year in 2021 for the utility.
“The record represents a single moment in the hour when demand for electricity was the highest yesterday,” says Simi Heer, BC Hydro spokesperson, in a statement. “Most of the increase is likely due to additional home heating required during this cold snap.”
In addition to the peak demand record on Monday, BC Hydro has observed an overall increase in electricity demand since Friday, and has noted that cryptocurrency mining electricity use is an emerging load in the province as well. Monday’s hourly peak demand was 18 per cent higher than Friday’s, while Calgary's electricity use soared during a frigid February, underscoring how cold snaps strain regional grids.
“BC Hydro has enough supply options in place to meet increasing electricity demand,” adds Heer, and pointed to customer supports like a winter payment plan for households managing higher bills. “However, if British Columbians want to help ease some of the demand on the system during peak times, we encourage shifting activities like doing laundry or running dishwashers to earlier in the day or later in the evening.”
BC Hydro is also offering energy conservation tips for people looking to lower their electricity use and their electricity bills, noting that Earth Hour once saw electricity use rise in the province:
Manage your home heating actively by turning the heat down when no one his home or when everyone is sleeping. Consider installing a programmable thermostat to automatically adjust temperatures at different times based on your family's activities, and remember that in warmer months wasteful air conditioning can add $200 to summer energy bills. BC Hydro recommends the following temperatures:
16 degrees Celsius when sleeping or away from home
21 degrees Celsius when relaxing, watching TV
18 degrees Celsius when doing housework or cleaning
