German police probe power grid sabotage after attacks cut 4,200 MW from power plants

Coordinated strikes on regional power facilities

German authorities are investigating separate attacks against electrical infrastructure in western and eastern Germany that took place on 1 September 2026. In North Rhine-Westphalia, sabotage at a substation near Bergheim and Rommerskirchen severed power supply lines, forcing the disconnection of five lignite-fired generation units operated by RWE Power. The affected facility has a total capacity of 4,200 megawatts, supplying approximately 10% of Germany's electricity demand. Grid operator Amprion and local utilities avoided consumer blackouts by rerouting power through alternative connections and renewable sources. Hours earlier in Brandenburg, perpetrators struck the Turnow-Preilack transformer station near the Jänschwalde coal plant, located 20 kilometres from the Polish border. That attack damaged overhead lines and briefly disconnected unit B before alternative routing restored stability.

Pyrotechnic launchers and technical methods

Investigators across both federal states identified similar technical mechanisms designed to disable high-voltage transmission lines. Cologne criminal police director Michael Esser reported that perpetrators constructed specialised launchers to propel conductive wire over overhead power lines, triggering intentional short circuits. Cologne public prosecutor Ulrich Bremer confirmed that the recovery of these launching systems provides strong evidence of deliberate disruption of public utilities and constitutional sabotage. Forensic teams in North Rhine-Westphalia are screening the recovered hardware for DNA traces, operating on the theory that devices were positioned in nearby fields days beforehand. Brandenburg Interior Minister Jan Redmann informed the state parliament's interior committee that only one of over a dozen projectile devices reached its target near Jänschwalde.

We must currently assume that the perpetrators were there several days earlier and installed the appropriate devices.

Wider pattern of critical infrastructure threats

The substation attacks coincide with an expanding series of security incidents targeting transport and energy nodes across Germany over the preceding month. Federal Interior Minister Alexander Dobrindt and Foreign Minister Johann Wadephul announced that federal agencies hold Russia responsible for an early August incident at Leipzig/Halle airport, where security staff discovered a drone fitted with explosives near an Antonov An-124 cargo aircraft. On the same night, a DHL transport plane collided with an unidentified flying object before diverting to Hanover. Investigators subsequently recovered a third drone in Kabelsketal on 14 August 2026. On 2 September 2026, an explosion at Augsburg railway station injured two people, prompting federal and state authorities to coordinate regional threat assessments.

We are dealing here with a hybrid attack scenario. For the first time, a drone with explosives was located on airport grounds. We must be aware of the threat.

Restoration efforts and extremist investigations

Utility operators began reconnecting disconnected generating units on 2 September 2026, restoring the first lignite block in western Germany by Wednesday morning and scheduling 1,600 megawatts of capacity to return by the weekend. While federal prosecutors investigate potential state-backed hybrid operations, state authorities are also examining domestic extremist networks. In January 2026, an arson attack on a Berlin cable bridge by the left-wing Vulkan Group disrupted power to 50,000 households and businesses. Data from the Federal Criminal Police Office recorded 321 cases of sabotage against critical infrastructure across Germany in 2025, with many remaining unsolved. Police in Essen, Cologne, and Brandenburg continue active searches around transmission corridors.
