Electricity has been restored to thousands of households in the southwest of the German capital, Berlin, after a power outage hit some 45,000 homes and 2,220 businesses on Saturday, the grid operator said on Sunday.

“By 3:23 a.m. (0223 UTC/GMT) on 4 January, we had been able to restore power to around 7,000 households and 150 businesses in several stages, particularly in the Lichterfelde area,” Stromnetz Berlin announced on its website overnight.

Suspected malicious act

The partial restoration of power means that some 38,000 homes and more than 2,000 businesses remain without electricity in the district of Steglitz-Zehlendorf, with Stromnetz Berlin saying it could take until Thursday afternoon to remedy the problem completely.

The outage, which leaves many of those homes without heating, comes as the city is experiencing a bout of very cold winter weather.

The affected district contains several care homes and medical facilities. Emergency services have transferred residents from at least two homes for the elderly.

The loss of power was caused by a fire at a cable link over the Teltow Canal that police are investigating as a possible arson attack after a letter sent to authorities claimed responsibility.

A spokeswoman for Berlin’s Senator for Economic Affairs Franziska Giffey said authorities believed that a malicious act was behind the fire.

The authenticity of the letter is being examined, but no group has been identified as a possible perpetrator so far.

However, Berlin’s state premier, Mayor Kai Wegner of Chancellor Friedrich Merz‘s conservative Christian Democrats (CDU), said the culprits were “obviously left-wing extremists,” whom he accused of endangering people’s lives with their actions.

Police call for better surveillance

The head of the Berlin branch of the GdP police union, Stephan Weh, called the attack “senseless” and without any legitimation, “even if the suspected arsonists again throw together all sorts of hypocritical reasons in a pamphlet on the end of the world.”

He called for an “unideological” debate on video surveillance in view of the fact that so many thousands of people were affected.

“Cameras mounted on electricity poles could help investigations but also have a preventive effect. We do without protective technology in the public space just because some people cry out loudly and cite Orwell’s ‘1984,’” he said. 

Stromnetz Berlin said there had been a similar attack on two power pylons in the city’s southeast in September that was politically motivated.
