Overview

• Stromnetz Berlin reconnected all affected households late Thursday via a temporary link between two lines, and the supply remained stable overnight.
• Roughly 50,000 customers were without electricity for about 60 hours, which the operator described as Berlin’s longest postwar blackout.
• Fires damaged high‑voltage cables at two masts in Johannisthal, which have been deemed stable enough to remain in use during the repair phase.
• Police and the domestic intelligence service are examining an Indymedia statement considered authentic by Berlin’s interior senator and assessing parallels to prior sabotage, including near the Tesla site in Grünheide.
• The temporary configuration reduces network redundancy and will constrain some expansion projects, while trams resumed service and labs and firms in Adlershof report significant refrigeration losses and lost revenue.
