Ukraine scales back nuclear output as grid repairs lag behind Russian strikes
Officials cite substation damage and reduced voltage levels as the primary drivers for the temporary capacity cuts across several oblasts.

Ukraine’s nuclear power plants are operating below their standard capacity following sustained Russian attacks on the country's electrical grid. First Deputy Energy Minister Artem Nekrasov confirmed the reduction during a briefing on the current operational status of the energy system.
The decision stems from physical damage to substations, which limits the network's ability to move power generated at the nuclear sites. Engineers must repair the damaged infrastructure before the plants can resume full output. This restoration process is expected to be gradual rather than immediate.
The strain is most acute in the capital region. In Kyiv and Kyiv Oblast, distribution operators have imposed network restrictions because of extensive damage to local equipment. Emergency power cuts are also active in Kharkiv Oblast. High-voltage grid voltage levels have dropped there, a consequence of earlier strikes on specific equipment.
As of the morning of November 4, consumers in Vinnytsia, Zhytomyr, Zaporizhzhia, Kirovohrad, Kharkiv, and Kherson oblasts experienced outages. These blackouts resulted directly from the physical impact of Russian attacks on the infrastructure.
The current grid stress follows a major escalation in attacks. On November 3, Ukrenergo, the state transmission operator, reported that Russian forces targeted energy facilities more than 20 times in a 24-hour period. During that same window, three drones were directed at a substation essential for the stable operation of the Khmelnytskyi Nuclear Power Plant.
