The Zaporizhzhia nuclear power plant in Ukraine has been without off-site power for over a week and is relying on emergency diesel generators, the UN nuclear watchdog said. The plant has a ten-day diesel supply on site.

The Zaporizhzhia nuclear power plant in Ukraine has been without off-site power for more than a week and is currently relying on emergency diesel generators, the UN's nuclear watchdog said on Saturday (August 29, 2026). The plant needs power to keep its six non-operating reactors cool, according to the International Atomic Energy Agency (IAEA).
The IAEA said the plant has only a ten-day diesel supply on site. It has not had a delivery to an off-site storage facility in about six months, but the plant was supplied with diesel on Thursday and Friday from another off-site location.
"The availability of diesel fuel is of paramount importance whenever a nuclear power plant loses off-site power," said IAEA Director General Rafael Grossi. "The current situation once again shows why reliable external power supply is essential for nuclear safety." He did not specify the cause of the power loss or give a timeline for restoration.
