Ukraine’s Zaporizhzhia nuclear power station lost the connection to its main external power line early on Tuesday morning (4 July), forcing it to rely on recently restored backup power supplies for the electricity it needs for essential nuclear safety and security functions.
International Atomic Energy Agency director-general Rafael Grossi said the six-unit station’s sole remaining 750 kilovolt (kV) power line – out of four available before the conflict – was disconnected at 01:21 local time. It was not immediately known what had prompted the power cut or how long it would last.
Ukraine’s nuclear operator Energoatom confirmed the disconnection on its Telegram and Facebook accounts.
