Power Restored in Berlin After Suspected Far-Left Attack Caused Longest Blackout Since WWII
Power is gradually being restored to thousands of Berlin households that had been without electricity for four days following a suspected far-left attack on critical infrastructure, authorities announced Wednesday.
The outage, which began early Saturday morning, affected approximately 45,000 households and 2,200 businesses when a fire damaged high-voltage cables running across a bridge over the Teltow Canal in southwestern Berlin. The incident left an estimated 100,000 residents in freezing temperatures without power, marking the longest blackout the German capital has experienced since the end of World War II.
Network operators had been able to reconnect many customers to the grid in the days following the attack, but by Tuesday, roughly 25,500 households and 1,200 businesses—primarily in the affluent Zehlendorf district—remained without electricity. Berlin’s power network operator confirmed Wednesday that service was being progressively restored to all remaining affected areas.
The incident has raised serious concerns about infrastructure security in Germany. Investigators are focusing on a written claim of responsibility from a far-left group whose statement was titled “Turning off the juice to the rulers.” The group claimed they had “successfully sabotaged” a gas-fired power plant in Berlin’s Lichterfelde district, stating their intention was to strike at the fossil-fuel energy industry rather than cause widespread power outages for residents.
Germany’s domestic intelligence agency noted that self-described “Volcano Groups” have been conducting attacks on infrastructure in Berlin and the surrounding Brandenburg state since 2011. A similar incident earlier in 2024 targeted a pylon supplying electricity to Tesla’s manufacturing facility near Berlin, temporarily halting production at the American automaker’s European gigafactory.
The severity of the attack has prompted federal authorities to intervene. On Tuesday, the German federal prosecutor’s office announced it was taking over the investigation, citing suspicions of anticonstitutional sabotage, membership in a terrorist organization, and arson.
The incident highlights growing vulnerabilities in urban infrastructure and comes amid increased political tensions in Germany. Far-left and environmental activist groups have intensified their activities targeting what they consider symbols of environmental harm and capitalism, though few previous actions have resulted in such widespread disruption to civilian life.
Energy security experts have long warned about the potential for attacks on critical power infrastructure, which can have cascading effects on healthcare, communications, and other essential services. The extended nature of this outage, occurring during winter conditions, raised particular concerns about vulnerable populations including the elderly and those with medical needs requiring electricity.
Local authorities and emergency services had established warming centers and provided assistance to affected residents during the four-day crisis. Many businesses in the affected areas were forced to close, contributing to significant economic losses across the affluent southwestern suburbs of the capital.
The attack and resulting blackout have sparked debate among German lawmakers about increasing security measures around critical infrastructure and potentially imposing harsher penalties for politically motivated sabotage affecting essential public services.
As power restoration continues, authorities are urging residents to check on vulnerable neighbors and to report any suspicious activity around infrastructure sites as the investigation into the perpetrators continues.
