What Happened

At around 6:00 AM on a freezing January morning, attackers set fire to a cable bridge spanning the Teltow Canal in southwest Berlin. The bridge carried five 110 kV high-voltage cables and ten 10 kV medium-voltage cables to the Lichterfelde combined heat and power plant. The fire destroyed all fifteen cables, collapsing power across multiple districts. (continue below)

Berlin Grid -- January 3, 2026

Around 45,000 households and 2,200 businesses lost electricity. Because the attack also severed the connection to the Lichterfelde CHP plant, thousands also lost heating in sub-zero temperatures. Hospitals and nursing homes were affected. An emergency shelter was set up at a sports center. Restoration took 4-5 days -- the longest power outage in Berlin since 1945.

The Vulkangruppe claimed responsibility, calling the attack "an act of resistance" targeting fossil fuel infrastructure. The investigation was escalated to the Federal Prosecutor under terrorism statutes. The BKA offered a 1 million EUR reward.

Timeline

~6:00 AM, Jan 3
Cable bridge set on fire
Attackers ignite a cable bridge over the Teltow Canal near the Lichterfelde CHP plant. The bridge carries 5 high-voltage and 10 medium-voltage cables.
Morning, Jan 3
15 cables destroyed
Fire destroys all five 110 kV and all ten 10 kV cables. Power collapses across multiple southwest Berlin districts. 45,000 households and 2,200 businesses lose electricity and heating.
Jan 3-7
Restoration hampered by conditions
Freezing temperatures, snow, and the need for fire scene evidence collection slow repair work. Affected districts include Nikolassee, Zehlendorf, Wannsee, and Lichterfelde.
Jan 6
Investigation escalated to federal level
The case is transferred to the Federal Public Prosecutor General under SS129a (terrorist organization) charges. The Vulkangruppe has claimed responsibility.
Jan 7-8
Full power restoration
After 4-5 days, engineers complete cable replacement and restore power to all affected areas. Berlin's longest outage since 1945 ends.
Jan 26
1 million EUR reward offered
The BKA offers Germany's largest-ever reward for information on infrastructure sabotage suspects. Deadline: February 24, 2026.

Root Cause

Physical destruction of a distribution chokepoint. The cable bridge concentrated 15 critical cables -- both transmission and distribution level -- in a single accessible location over a waterway. No redundant paths existed. Destroying this one structure severed both electricity and heating supply to an entire section of the city. The same pattern as the Johannisthal attack four months earlier: exposed, above-ground infrastructure with no security and no redundancy.

VPP Relevance

4 days of self-sufficiency
Homes with solar panels and VPP-connected batteries could have maintained power through the entire 4-day outage -- especially critical in freezing winter conditions where heating loss is life-threatening.
No cable bridge to burn
A VPP's generation and storage assets sit on rooftops and in garages across the city. There is no single bridge, pylon, or substation whose destruction can black out 45,000 homes.
Microgrid formation
When the grid goes down, a VPP controller like Flexa can coordinate nearby homes into microgrids -- sharing solar generation and battery reserves among neighbors to extend autonomy far beyond what a single home battery provides.
