Power outages have returned to Kyiv after Russian attacks damaged the energy infrastructure supplying the capital, with authorities warning that the situation could worsen as Russia intensifies its campaign against Ukraine’s energy system ahead of winter.

Russia has repeatedly targeted Ukraine’s power, heating, and other critical infrastructure to disrupt the systems civilians depend on and create a humanitarian crisis during winter. Ukrainian officials have repeatedly warned that this winter will be especially severe, as Russia has expanded its strike capabilities since the summer and Ukraine continues to face shortages of air-defense systems needed to protect its energy infrastructure.

Ukrenergo said on 8 October that emergency outages were being imposed in parts of Kyiv and Kyiv Oblast because of falling voltage in the high-voltage network. Previously announced hourly schedules were suspended, with predictable schedules to resume once the system stabilizes.

In the evening, further disruption came after a Russian attack on an energy facility important to Kyiv. Energy Minister Denys Shmyhal said that energy workers were working to restore power.

Kyiv has been under Russian attack throughout the day, with four people killed and 19 injured.

The attack continues into the evening of 8 October, with air raid alerts active across most of the country.

Kyiv loses power, water, and public transport

The damage throughout the day quickly spread beyond electricity.

The Kyiv City Military Administration said power disruptions temporarily halted metro trains and escalators. Part of the capital’s public transport system was also suspended because of the lack of electricity.

Reduced power to water infrastructure caused lower pressure on the right bank of the Dnipro, particularly in the Holosiivskyi, Sviatoshynskyi, Solomianskyi, and Shevchenkivskyi districts. Some buildings could temporarily lose water, the administration warned.

Russia is hitting the energy system as winter approaches

The outages come as Russia has stepped up attacks on Ukraine’s energy infrastructure ahead of the heating season.

Ukrenergo said Russian attacks had caused new power outages in Donetsk, Kharkiv, Sumy, and Zaporizhzhia oblasts. The company said damaged equipment was already limiting the grid’s ability to supply consumers and warned that further Russian strikes could rapidly change the situation.

For 9 October, Ukrenergo announced all-day power restrictions in affected regions, including hourly outages for some consumers. Industrial and business consumers will also face restrictions. The company urged Ukrainians to conserve electricity, particularly during the evening peak from 5 p.m. to 10 p.m.

Ukraine’s energy authorities have been warning about the consequences of repeated Russian attacks for months. In late September, Prime Minister Serhii Koretskyi said attacks on energy facilities had been occurring almost daily since the summer, with the September 29–30 attack marking the first massive combined strike on the energy system since the previous heating season.

The renewed strikes mark the beginning of Russia’s winter campaign against the energy system, with Russian missiles and drones increasingly targeting power-generation and transmission infrastructure in Kyiv and surrounding regions.

Russia has openly threatened another winter of blackouts

The campaign follows years of Russian attacks aimed at disrupting the infrastructure that keeps Ukrainian homes heated and supplied with electricity and water during the winter.

In August, Russia’s Defense Ministry openly taunted Ukrainians over its attacks on energy-related infrastructure, posting images of attack drones with the message that Ukrainians would “get a freeze” in winter. 

Russia’s strategy has repeatedly linked attacks on electricity infrastructure to disruptions in heating and water supplies. This makes damage to the power grid particularly consequential as temperatures fall: a strike on an electrical facility can leave not only homes without lights, but also affect water pumps, heating systems, transportation, and other essential services.

The return of blackouts to Kyiv before the heating season is fully underway is an early indication of the pressure Russia’s renewed energy campaign is putting on Ukraine’s civilian infrastructure.

Two 14-year-old boys were killed when an explosive device detonated in the evening in the Konotop district of Sumy Oblast, according to the statement by Oleh Hryhorov, head of the Sumy Regional Military Administration. The children encountered the dangerous device in a field, suffered severe injuries, and died at the scene, the statement said.

In 2022, Russian forces occupied parts of Sumy Oblast, but Ukraine liberated the region in April. Russia intensified its offensive again in 2025. Today, mines, unexploded ordnance and Russian drones shot down over the region pose a danger, as their warheads can detonate after falling. Overall, 146 children in Ukraine have suffered mine-related injuries, former Interior Minister Ihor Klymenko reported in April. For example, two months ago, an 11-year-old boy and a 15-year-old boy in Sumy Oblast were injured when an explosive device detonated.

Hryhorov expressed his condolences to the parents and relatives of the victims and urged people to remain cautious:

“Please be as careful as possible and remind children: do not approach unknown or suspicious objects, touch them, or try to move them. Take care of yourselves and your loved ones,” Hryhorov said.

Demining efforts continue in Sumy Oblast

On 24 February 2022, Russian forces entered the territory of Sumy Oblast. The first battles in the region took place that same day. In particular, Russian forces attempted to break through to Sumy, but Ukrainian troops repelled the offensive. On 11 April 2022, Ukraine restored control over the entire Sumy region.

As early as 7 June 2022, deminers were working in the Konotop, Sumy, and Okhtyrka districts, according to the Government Portal. That day, they surveyed areas and neutralized explosive devices.

The work of deminers remains deadly dangerous. In September 2024, two pyrotechnicians from Dnipropetrovsk Oblast were hit by a mine while demining Sumy Oblast: one died, while the other was hospitalized. In July 2025, deminer Oleh Petrenko was killed during humanitarian demining operations in Shostka District when a Russian FPV drone detonated, the State Emergency Service of Ukraine reported. Another pyrotechnician was injured, the statement said.

Nevertheless, the work continues despite the danger. In 2025, State Emergency Service deminers in the Sumy Oblast found and neutralized 5,283 explosive devices, the agency said in April. Sumy Oblast ranked sixth among all Ukrainian regions by this figure.

Twenty-two percent of Ukraine’s territory is potentially contaminated with explosive devices — more than 133,000 square kilometers, former Interior Minister Ihor Klymenko reported in April this year. Since the beginning of the full-scale invasion, State Emergency Service and National Police deminers have surveyed more than 248,000 hectares of territory and found more than 1 million 112 thousand explosive devices, the statement said.
