Overview
- Stromnetz Berlin is working on provisional lines and complex high‑voltage repairs that are constrained by persistent frost.
- The blackout was caused by a fire on key transmission cables, and police say they have received a purported claim of responsibility that is under investigation.
- Daytime temperatures near minus 5°C and nighttime lows around minus 12°C are compounding the loss of heating, hot water and reliable internet.
- Officials and crisis advisers urge residents to relocate to powered homes if possible, check on neighbors and avoid open flames because of carbon monoxide risks.
- Parts of Steglitz‑Zehlendorf, Lichterfelde and Zehlendorf remain affected, and some streets could regain service later than Thursday.
