On the night of Saturday, December 6, Russia carried out a massive attack on Ukraine's energy infrastructure.
As a result of the strikes on transmission systems and grid facilities, some nuclear power plants were forced to temporarily reduce generation capacity.
Anatolii Zamulko, acting head of the State Energy Supervision Service (Gosenergonadzor), reported this on the "Yedyni Novyny" national telethon. According to him, the latest attack was Russia's eighth massive strike on the energy sector since the beginning of 2025. He explained that the enemy targeted facilities responsible for redistributing electricity between regions, which necessitated "a slight reduction in production at nuclear power plants" to stabilize the system. At the same time, Zamulko stated that the restoration process is already underway.
Following the shelling, hourly power restriction schedules were intensified across the country. Gosenergonadzor also warned that as temperatures drop, the load on the system will increase, meaning the application of blackout schedules could become more noticeable for consumers.
In addition to the energy strikes, the city of Fastiv in the Kyiv region was hit by "Shahed" drones during the overnight attack. Fires broke out on the territory of the railway station and the motor-car depot. Ukrzaliznytsia (Ukrainian Railways) reported damage to suburban trains, leading to adjustments in movement and the cancellation of some services. According to the Regional Military Administration (RMA), large-scale fires were recorded in three districts of the region, and three people were injured.
The Air Force reported that on the night of December 6, Russia attacked Ukraine with a total of 704 drones and missiles, including "Kinzhal" hypersonic missiles, "Iskander" ballistic missiles, and "Kalibr" cruise missiles. Air defense neutralized 615 targets.
Ukrenergo (Ukraine's national energy company) noted that emergency power shutdown schedules had been introduced in certain regions. The Ministry of Energy reported attacks on generation, distribution, and transmission facilities in several oblasts, including Kyiv, Chernihiv, Lviv, Odesa, Zaporizhzhia, Dnipropetrovsk, Mykolaiv, and Kharkiv.
