Overview
- Two linked incidents that used self-built projectile devices and cable tampering hit substations in Jänschwalde and Bergheim on Tuesday and led operators to take several power blocks offline briefly for safety checks.
- In the days since investigators have found suspected launcher devices at sites in Dormagen and Bergheim, mounted a large cordon around a Ganderkesee substation and expanded searches near Weisweiler based on tips in a claimant letter.
- Prosecutors in Cologne and Brandenburg have opened criminal and terrorism‑related probes under serious statutes and are treating the pattern of recent incidents as potential politically motivated sabotage while attribution remains unproven.
- A handwritten Bekennerschreiben received by taz describes a lone actor who cites harm from fossil fuels but authorities have not authenticated the author or confirmed the letter links the sender to the attacks.
- Security agencies say the incidents expose wider vulnerability: a confidential BKA briefing records more than 165 suspected sabotage cases in 2026 and officials are debating faster repairs, expanded drone‑defense powers and who will pay to harden dispersed grid sites.
