Energoatom says Zaporizhzhia plant lost external power and switched to diesel generators

Situation Overview

On 8 November at 02:36, the Zaporizhzhia Nuclear Power Plant (ZNPP) lost power from the last remaining operational 330 kV Ferrosplavna-1 line that connected it to Ukraine’s power grid, Ukrinform reported. Energoatom said an automatic attempt to reconnect the line failed and the plant’s own power needs are now met solely by backup diesel generators. Energoatom warned that complete loss of external power poses a critical threat to nuclear and radiation safety and said it was the 16th instance of ZNPP completely losing external power since the beginning of 2026. The next concrete development to watch is whether Energoatom reports successful restoration of the Ferrosplavna-1 line or continued operation solely on diesel generators.

Geopolitical Implications

1. 01

   The incident highlights how war-related grid disruptions can directly affect nuclear safety systems at a major facility.

2. 02

   Repeated external power losses increase international scrutiny and pressure to protect critical infrastructure.
