Coldest January in 16 years sent electricity meters across the country into overtime

Cold winter weather and more electric cars caused Jutland electricity consumers to use a fifth more electricity than in January 2025.

Electricity meters across the country worked overtime in January. A record amount of electricity was sent out into the sockets, according to several electricity grid companies.

The company N1, which supplies 800,000 homes and businesses in Jutland with electricity, sent 500 million kilowatt hours out through the sockets. That is 21 percent more electricity than the same month last year and a new record, says press and communications manager Frederik Gelstoft Schmidt.

- We probably expected that we would deliver more electricity in January this year, but the fact that the increase is so high has surprised us a bit, he says.

He mentions, among other things, the cold weather as part of the explanation for the high electricity consumption. The Danish Meteorological Institute (DMI) has previously stated that the past month was the coldest January in 16 years.

- January was cold over a longer period, and this has certainly meant that circulation and heat pumps have been running more, and that electric cars have been charged an extra time, says Frederik Gelstoft Schmidt.

Electric cars are another part of the explanation for the high electricity consumption. There are around half a million electric cars, and they constitute an increasing share of the car fleet.

On Zealand, the electricity grid companies Cerius-Radius have also seen an increase in electricity consumption in January. Here, 16.5 percent more electricity was used than in the same month last year. Just like on the N1, this is a record, Cerius-Radius reports.

- The frosty days cause electricity consumption on residential roads to increase dramatically. Even though there are still many gas boilers and the rollout of district heating is gaining momentum, there are also many who are turning up their electric radiators or have invested in heat pumps, says Cerius-Radius CEO Cäthe Bay-Smidt in a press release.

The same tone is heard from the electricity grid company Trefor El-net, which supplies the Triangle area with electricity. Electricity consumption here increased by 19 percent compared to January last year.

Like the other companies, the increase is attributed to a combination of cold winter weather, an increasing number of homes heated with heat pumps, and more electric cars. This is stated in a press release from the company.
