Jan Redmann, Brandenburg's interior minister (CDU), said in a statement reported on 2026-09-02 that the two attacks on power supply facilities in Jänschwalde and Bergheim were probably part of a coordinated attack on Germany's energy supply, and that the Federal Prosecutor General was examining whether to take over the investigation. ^[1] Police in Brandenburg are investigating an attack on a power substation in Turnow-Preilack that caused short circuits on two high-voltage lines and a temporary interruption. ^[2] Jan Redmann, head of the Ministry of the Interior for Brandenburg, stated on 2026-06-25 that the perpetrators of the energy grid sabotage attempt near the Jaenschwalde power plant must have been on the site several days in advance. ^[3] German investigators said they assume that the disruption at the Bergheim substation near Cologne on 2026-09-01 was due to anti-constitutional sabotage, and that they see parallels with the attack in Brandenburg. ^[4] According to the tabloid Bild, over 20 self-constructed rockets potentially equipped with time fuses were used in the attack on the energy grid, though services did not confirm these details. ^[5] Authorities found improvised explosive charges at a transformer station in the municipality of Turnow-Preilack, approximately 20 km from the Polish border, attempting to introduce conductive material into high-voltage lines. ^[6] Jan Redmann stated on 2026-06-25 that the construction and installation of the sabotage devices required a certain level of technical knowledge. ^[7]
