Zaporizhzhia nuclear power plant restored external electricity supply after repairs returned its 330-kV Ferosplavna-1 transmission line to service.

The restoration followed a complete loss of off-site electricity earlier on November 8. The International Atomic Energy Agency, or IAEA, said the plant lost its connection to Ferosplavna-1, its only external power line at the time. The plant relied on emergency diesel generators for reactor cooling during the interruption.

The plant’s account attributed the disconnection to line damage that triggered protection equipment. Its official social-media announcement said repairs returned the 330-kilovolt line to operation and restored external supply. Staff monitored operating parameters and implemented safety measures during the incident.

Earlier IAEA reporting left the cause and location of the disconnection unresolved. The agency’s team had also been informed that available fuel could run a limited number of emergency diesel generators for two weeks; that statement should not be expanded into two weeks of unrestricted plant operation. A later IAEA update confirmed power restoration, which concerns electricity supplied to the plant rather than a reported resumption of nuclear generation.
