In brief

• Ukraine's nuclear plants have cut electricity output after Russian strikes on generation sites and substations.
• Power cuts affect six regions, with Kyiv and Kyiv Oblast under the most severe restrictions.
• The ministry says output will return to nominal levels gradually as networks are repaired, with no firm timeline.

Nuclear plants scale back generation

Russian forces keep striking Ukrainian power generation sites and the substations that deliver electricity to consumers, and as a result the country's nuclear plants have had to run below their usual output. First Deputy Energy Minister Artem Nekrasov gave the update at a briefing on November 4 (Через удари РФ по енергоінфраструктурі АЕС вимушено знизили потужність генерації — Міненерго – TSN) (Nuclear power plants forced to reduce output after Russian attacks – Energy Ministry – Ukrinform). He said output will climb back to nominal levels gradually, as crews repair the damaged networks.

Regions affected by outages

As of the morning of November 4, attacks had left parts of the population without power in six oblasts: Vinnytsia, Zhytomyr, Zaporizhzhia, Kirovohrad, Kharkiv and Kherson (Через атаки РФ на енергетику України АЕС вимушено знизили потужність генерації — Міненерго – Suspilne). The situation is hardest in the capital region. In Kyiv and Kyiv Oblast, distribution operators are applying network restrictions because of serious damage to energy equipment (Украинские АЭС снизили мощность генерации — Минэнерго назвало регион с самой сложной ситуацией – NV).

Emergency cuts and schedules

In Kharkiv Oblast, emergency shutdowns are being used because of damage from earlier attacks and a voltage drop in the high-voltage grid. Normal supply schedules in the region will only return once the system stabilises. Across most of Ukraine, hourly outage schedules apply to households, and industrial users face power limits. Energy officials have urged residents to follow updates on the schedules.

What comes next

The ministry has not given a timeline for full recovery of the plants' output. Its statement points to a step-by-step process that depends on how quickly repair teams can restore the damaged lines and substations. Until then, residents in the affected regions should expect scheduled outages and follow official updates from their local operators.
