Zaporizhzhia nuclear power plant loses all external power for 30 minutes – IAEA

Rafael Grossi, Director General of the International Atomic Energy Agency (IAEA), has said that the Zaporizhzhia Nuclear Power Plant (ZNPP) has temporarily lost all external power overnight for the first time since Russia's full-scale invasion of Ukraine.

Details: The plant briefly lost all off-site power during the night.

The IAEA said the Zaporizhzhia Nuclear Power Plant was reconnected to a 330 kV power line after a half hour outage, but the 750 kV line remains disconnected.

On the night of 5-6 December 2025, the Russian forces again attacked energy infrastructure in several oblasts of Ukraine, seriously damaging equipment at thermal power plants.

Background:

• The volume of projected power consumption restrictions has had to be increased due to a large-scale Russian attack on 6 December.
• The protective shelter at the Chernobyl Nuclear Power Plant, built to contain radioactive material from the 1986 disaster, can no longer perform its main safety function after damage caused by a drone.
