Technical fault caused Berlin substation fire and explosion, police chief says

Overnight fire at the Bissingzeile substation

Emergency services in Berlin were mobilized in the early hours of Monday, 7 September 2026, following reports of a fire at an electrical substation on Bissingzeile in the Tiergarten district. The Berlin Fire Department logged the emergency alarm at 02:41, dispatching operational units to the compound near the borders of Mitte and Moabit. Responding crews encountered flames burning across an on-site construction area, an adjacent transporter vehicle, and structural sections of the substation installation. Firefighters successfully extinguished the blaze before flames could reach critical underground conduits. Per Kleist, the vice chief of the Berlin Fire Department, stated that the subterranean utility tunnel containing high-voltage transmission lines remained undamaged. Local grid authorities confirmed that the electrical supply across the capital remained fully operational with no disruptions, and no injuries were recorded.

Police findings identify technical malfunction

Initial forensic assessments by Berlin security officials determined that the facility was damaged by an internal system fault rather than an intentional attack. Berlin Police President Barbara Slowik Meisel presented the preliminary findings during a morning session of the Interior Committee of the Berlin House of Representatives. She explained that current evidence indicates a technical defect triggered a severe short circuit, which subsequently produced an explosion on the site. Specialists from the forensic science division of the Berlin State Criminal Police Office (LKA) conducted comprehensive on-site examinations throughout the morning. Investigators worked directly alongside engineers from the facility operator to evaluate the damaged equipment and verify the sequence of the technical failure.

Heightened alert following regional sabotage

The Berlin incident occurred against a backdrop of security alerts across the German energy sector following recent physical attacks against grid installations. In the days prior to the Berlin fire, coordinated attacks struck electrical substations in Brandenburg and North Rhine-Westphalia. In a related escalation, security personnel in Saxony discovered multiple homemade explosive devices planted at two separate electrical substations. Forensic specialists from the Saxony State Criminal Police Office safely neutralized the improvised mechanisms before detonation. The devices were specifically engineered to trigger catastrophic electrical short circuits across high-voltage transmission lines without causing direct structural collapse, though neither power interruptions nor facility damage occurred.

They were intended to cause damage to the high-voltage electrical lines through a short circuit.

Federal investigation and ongoing manhunt

Federal authorities intensified their investigation into the coordinated infrastructure attacks, treating the incidents outside Berlin as politically motivated sabotage. Federal Interior Minister Alexander Dobrindt stated that security agencies are proceeding on the premise of climate extremism as the driving motive behind the targeting of electrical nodes. Investigators are pursuing an active search for a 48-year-old suspect from Gevelsberg in North Rhine-Westphalia, who left behind two confession letters that intelligence analysts evaluated as authentic. A localized tactical search conducted by Cologne police near Hambacher Forst, which began west of Cologne near Kerpen, concluded without locating the individual or recovering additional evidence. The federal manhunt remains underway across multiple states as authorities assess regional utility protections.
