Ukraine's Zaporizhzhia Nuclear Power Plant has been reconnected to the electricity grid after repairs were carried out under a localised ceasefire brokered by the International Atomic Energy Agency (IAEA).

The UN nuclear watchdog said the facility regained access to off-site power on Saturday, following nearly three days without an external electricity supply, one of the longest such outages since Russia's full-scale invasion of Ukraine began.

The plant, Europe's largest nuclear facility, lost its final remaining back-up power connection late on Wednesday after an attack on an electrical substation across the Dnipro River severed the Ferosplavna power line.

According to the IAEA, the outage marked the 19th time the site has lost access to off-site power during the war.

During the blackout, the plant was forced to rely on emergency diesel generators to provide the electricity needed to cool its six reactors, all of which are currently shut down. Although the reactors are no longer producing power, they still require continuous cooling to prevent overheating and ensure safe operation.

IAEA Director General Rafael Grossi has repeatedly warned that attacks affecting the plant's power infrastructure pose a significant risk.

The agency said repair teams were able to restore the damaged connection after a temporary ceasefire was agreed in the immediate area, allowing engineers safe access to the site.

The Zaporizhzhia plant has remained at the centre of international concern since it was seized by Russian forces in the early months of the war. Both Ukraine and Russia have repeatedly accused one another of endangering the facility through military activity near the site.
