Overview

• Stromnetz Berlin says roughly half of the 44,000–50,000 affected customers are reconnected, with about 20,000–25,000 still out and full restoration expected during Thursday.
• Crews are completing deep excavation and reconnecting arm‑thick cables using large dust‑free ‘muff’ couplings, a multi‑hour procedure needed to stabilize the grid.
• The LKA’s state protection unit leads the probe, reviewing a claim signed “Einige Anarchist:innen” that framed the attack as a strike on Adlershof; police consider the arson politically motivated.
• Investigators report accelerants and steel chains were used at two 110 kV masts in Johannisthal, melting insulation and triggering a short circuit that cut power across southeast Berlin.
• Schools and care homes were hit, ventilated patients were moved, parts of the 110/112 emergency call system were backed up with 15 intake points and BVG vehicles, and tram, S‑Bahn and traffic signals saw disruptions as officials condemned the attack; an SPD lawmaker suggested specialized or insider knowledge may have been involved, and the federal cabinet plans to approve a critical‑infrastructure law.
