Electricity consumption in Finland has reached an all-time record high, according to national grid operator Fingrid, as temperatures across the country plummet on Thursday.

In a post on social media platform X, Fingrid wrote that a consumption rate of 15,128 megawatts per hour was registered on Thursday morning — a new record — adding further that the level may still rise.

The operator also noted that Finland's power system is functioning as normal, despite the spike in demand, and there is currently a sufficient supply of electricity.

Cold weather advice for motorists

The cold snap is also putting pressure on another source of energy — car batteries.

Daniel Isoaho of auto accessories retailer Vaasa Motonet told Yle that a car battery charger is a very useful tool during these extreme weather conditions.

"You can put the battery on a maintenance charger overnight if you've already had problems before. If the car is standing unused for a longer period, it's a good idea to remove the battery entirely," Isoaho said.

A car battery's so-called maintenance charger (ylläpitolaturi in Finnish) works in a similar way to a phone charger. The charger is first connected to the battery and the other end is plugged into a socket.

Isoaho also advises motorists to always carry a jump starter in case they get stranded. However, it is important to carefully read the car manufacturer's instructions about using these devices, as incorrect usage could damage the car's electronic control units and fuses.

In addition, driving for longer periods can extend a car battery's lifespan and improve its performance. Cars that are mainly used around a city, for example, should also be driven for at least half an hour once or twice a week.
