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.

A drone attack overnight on 8 October caused a fire that hit part of Yandex's data center in Sasovo, Ryazan Oblast, about 580 km from Ukraine, and the site is fully stopped, the Russian tech company told Russian media. The data center sits on the grounds of Sasta, a sanctioned machine-tool plant, Russian outlet Astra said, citing Wikimapia data. Astra's OSINT analyst found from eyewitness footage that the fire hit the plant.

Since late September, Russia has been striking data centers in Kyiv that keep Ukraine's internet and online services running. Now a drone attack has stopped one of the data centers that Russia's largest tech company relies on.

Yandex counts the damage

Yandex warned that some services may be unavailable, while its core services kept running and no one was hurt. Ryazan Oblast Governor Pavel Malkov claimed two drones were downed, a roof caught fire at an enterprise in the Sasovo district, and windows were blown out in several homes.

The power failure took down a wide range of Yandex Cloud infrastructure, including computing capacity, networks, data storage, databases, Kubernetes, cloud services, AI, and security and monitoring systems, Ukrainian outlet ZN.ua reported, citing Exilenova+.

Ukrainian monitoring channel Exilenova+ reported that the plant was hit, without naming an attacker. The channel said Sasta, which claims a place on Russia's register of defense-industry companies, makes computer-controlled machine tools, including five-axis machining centers, and previously supplied the Tactical Missiles Corporation (KTRV) and Roscosmos. The plant's value to the arms industry lies in machines that cut precision parts, not in finished weapons, the channel said.

Citing Exilenova+, Militarnyi reported that Ukraine's Defense Forces hit the plant. It also linked Sasta to Iskander missile supply chains. No source has said whether the plant or the data center was the target, and no Ukrainian official has claimed the Sasovo strike. Sasta has been under US sanctions since November 2023, UK sanctions since February 2024, and Ukrainian sanctions since April 2025, a sanctions database shows.

Salavat: Kyiv reports a hit

Ukrainian forces hit the Gazprom Neftekhim Salavat complex in Bashkortostan, about 1,380 km from the front line, causing a fire, Ukraine's General Staff said. It said the complex processes up to 10 million metric tons of hydrocarbons a year and serves Russia's armed forces. Its key unit, the ELOU-AVT-6 primary oil refining unit launched in 2012, can process 6 million metric tons a year, Militarnyi reported. Astra's analyst placed the fire a few kilometers outside Salavat, possibly near the refinery.

Salavat Mayor Marat Zagidullin claimed that debris from several drones fell in the industrial zone that morning and started a fire.

"The enterprise continues to work," he said.

Astra noted earlier hits on the complex on 24 September 2025, on 14 July 2026, when refining fully stopped, and on 13 August 2026.

Russia's strikes on Ukraine's data centers

Russia has repeatedly hit data centers in Kyiv since 23 September. Strikes hit the COSMONOVA data center twice, the second time knocking it out, and the Parkovyi data center stopped working completely on 1 October after a series of strikes. In early October, Russia destroyed the dline.ua data center in Kyiv.

Russia is concentrating missiles on a smaller, more specific set of targets, and its jet-powered attack drones are part of the reason, the Institute for the Study of War (ISW) assessed. Its combined attack overnight on 7 October killed 22 people in Pryluky, the State Emergency Service (SES) said as of the morning of 8 October. Russian milbloggers noted the shift the same day.

Russia often uses concentrated drone and missile strikes to overwhelm localized Ukrainian air defenses and destroy urban centers, ISW noted. Pryluky, where the strike killed children, was one of the areas a Russian channel says drew a significant share of the Kh-101s that night. With winter close, ISW expects the same pattern against Ukraine's energy grid, with jet drones partly letting Russia keep its missiles for priority targets without firing many more.

Missile waves on a few areas, Russian channels claim

Russia launched 48 Kh-101, Iskander-K, and Kalibr cruise missiles overnight on 7 October, Ukraine's Air Force reported. It also fired ballistic missiles, Zircon and Oniks anti-ship missiles, and 130 strike and decoy drones, 46 of them jet-powered Shahed-type models.

Russian milbloggers claimed the same day that Moscow had grouped a large part of its missile salvo into repeated waves on a few areas, while other weapons kept stretching Ukraine's air defenses elsewhere. The pro-war Russian Telegram channel Dva Mayora described the change as a switch from striking with splayed fingers to a series of hits with missile "fists." Defenders must then absorb a sharply rising load around one chosen site as one wave follows another, the channel claimed.

Citing Ukrainian monitoring channels, it claimed that roughly 30 or more Kh-101 cruise missiles flew toward Pryluky, Kremenchuk, Svitlovodsk, and Oleksandriia in Chernihiv, Poltava, and Kirovohrad oblasts. It put the Kremenchuk group at up to 15 missiles, Kh-101s and Kalibrs among them, aimed at the area of Kremenchuk and its hydroelectric plant.

Jet drones take some of the load off Russia's missiles

ISW said the jet-powered versions penetrate Ukrainian air defenses deeper and more reliably than propeller models. In ISW's assessment, that partly lets Russia concentrate cruise and ballistic missiles on priority targets without significantly raising missile use. Russia builds about 3,000 Geran-4 and Geran-5 jet drones a month, Ukraine's military intelligence agency (HUR) told Militarnyi in August.

ISW expects Russia to apply the pattern in a likely brutal winter campaign against energy infrastructure. Russia likely intends to make city life untenable and force Ukraine to capitulate to its demands, ISW assessed. Such tactics have not worked before and are unlikely to work now, analysts added.

They called cheap countermeasures to jet drones and small cruise missiles vital, alongside Western air defense aid such as US-made Patriots, which can stop ballistic missiles. Ukraine has already paired a Soviet-era Kub launcher with American RIM-7 interceptors to catch jet drones.

A Ukrainian Sargan-3000 sea drone shot down a Russian Shahed flying on a mesh radio network, Ukraine's Navy reported on 7 October. Ukrainian sea drones have downed Russian aircraft before, but with missiles. This one used a machine gun.

Russia has been hitting Odesa with air attacks that come in waves with short gaps between them. Guarding the sky over water is harder than over land. Since fall 2025, Russia has also used mesh radio networks to reroute Shaheds mid-flight and dodge Ukrainian air defenses. That leaves Ukraine needing more ways to meet these drones out at sea, before they reach its ports and coast.

A Shahed steered by radio

A mesh-network drone passes its control signals along a chain of radio relays, drone to drone and on to ground antennas. That lets a Russian operator steer it in flight.

In May, Serhii "Flash" Beskrestnov, then a Defense Ministry adviser, said only about 5% of Shaheds had got through in a recent Russian strike, and predicted that Russia would answer with jet-powered versions and strikes near the border. By July, Ukraine was testing jamming against mesh-controlled jet Shaheds, he said.

The Sargan-3000 fired its Protector remote weapon station, Militarnyi reported. The station is a remotely operated 12.7-mm (50-caliber) machine gun with electro-optical sights. The outlet added that the Sargan-3000 is designed for combat missions far from Ukraine's coast.

Built for the open sea

Ukraine's Navy took the Sargan-3000 into service in April 2026, according to Militarnyi. The drone boat has a combat radius of up to 1,600 km. It moves at 40–55 knots and carries up to 450 kg of payload.

In September, a Sargan-3000 sank a Russian uncrewed boat with machine-gun fire. Militarnyi called it the first battle between uncrewed sea platforms in history. Analyst H.I. Sutton wrote that the boat carried a Protector made by Norway's Kongsberg. That is the same weapon station named in the October shootdown. Sutton added that Russian attack sea drones work closely with Shaheds, which can relay the boats' mesh radio signals.

Ukraine plans 135 basic mobile shelters for civilians at 28 of its border crossings, the State Agency for Restoration and Infrastructure Development said on 7 October.

Since the start of September, Russian drones have repeatedly struck crossings on Ukraine's borders with Moldova and Romania. Since mid-September, strikes have also reached the Polish border near the Yahodyn crossing in Volyn Oblast. On 13 September, a Russian drone strike set a gas station near the crossing on fire. On 28 September, the blast wave from another strike damaged the checkpoint building. On 25 September, First Deputy Minister for Restoration, Infrastructure and Transport Serhii Derkach said Ukraine is exploring with its neighbors whether some checkpoints could move onto their territory. No agreement has been reported. On 2 October, Moldovan Interior Minister Daniella Misail-Nichitin said Moldova had set up shelters next to its crossings with Ukraine and started relocating staff from joint checkpoints.

135 shelters for travelers and border staff

The shelters will stand at the crossings and on the roads leading to them. Regional recovery services in Vinnytsia, Odesa, Chernivtsi, Zakarpattia, and Volyn oblasts are running the purchases. The agency said the shelters will make the border safer for people crossing it and for checkpoint staff.

In Chernivtsi Oblast, one of the 10 tenders the agency lists on Prozorro, Ukraine's public procurement system, covers eight shelters for 50 people each and three for 20 each, Ukrinform reported. They will stand on the approach road to the Porubne–Siret international crossing on the Romanian border. The work is expected to cost UAH 38.5 million (about $855,000), excluding VAT.

Russian strikes on crossings

On 5 October, at about 09:38, a projectile fell near the Palanca–Maiaky–Udobne crossing on the Moldovan border. It ricocheted off the ground into a shuttle bus parked by the barrier and also damaged a control booth. One Moldovan border officer suffered light injuries, and the crossing was suspended, Moldova's Border Police said, linking the incident to Russia's attacks on Ukrainian infrastructure. Moldovan authorities did not specify the projectile's type or origin.

Overnight on 9 September, Russian drones struck the Starokozache crossing with Moldova, killing two people and injuring three. On 1 September, Russian Shahed drones hit the Orlivka ferry crossing on the Danube, opposite Romania's Isaccea, and temporarily shut it down. Another Russian strike on 6 September halted the crossing again.

Russian forces appear to use AI to plan air attacks and recognize targets amid raids on Ukrainian cities. This may include recent air attacks on Odesa that have come in waves with short gaps, Deputy Air Force Commander for Air Defense Colonel Yurii Cherevashenko says, Ukrinform reports.

Russia has already equipped its jet-powered Geran-4 drones with machine vision, allowing them to recognize and track targets on their own in the final seconds of flight. Recently, a single jet drone hit a locomotive in Odesa Oblast in late September and killed two railway workers.

The scale of Russia's AI use is hard to measure, Cherevashenko continues, but Ukrainian specialists already see its elements in how attacks are organized. The long, wave-by-wave strikes on Odesa would be far harder to plan and coordinate without it, he believes.

"Russian forces use AI to lay out attack routes and to recognize targets," Cherevashenko says, framing it as his own assessment rather than a confirmed fact.

The sea is harder to defend than land

Odesa Oblast is home to the biggest port in Ukraine, "Southern". Protecting it is a challenging task as guarding the airspace over water is tougher than over land, Cherevashenko says. Some air defense assets do not perform as well at sea, and in some cases, crews can intercept a target only as it approaches.

Weather adds to the problem, with storms and fog, while the open sea gives Russia more freedom to choose drone routes and launch points. To protect ports and the coast, Ukraine uses drone motherships, platforms that carry other drones aloft to extend their flight time and keep watch over set areas.

Ukraine answers AI with AI

Ukraine is also building its own AI for air defense. Automated turrets using machine vision now help counter Russian drones. According to Army Media, the Air Force says such turrets have scored their first shoot-downs, including of Geran-5 jet drones, with one soldier saying 50 rounds were enough to bring down a Geran.

Ukraine's Defense Ministry is going further. In late September, it unveiled an AI system called SPECTR, built by its A1 Artificial Intelligence Center and already in testing with several combat units, to analyze battlefield data, predict Russian moves, and suggest options to commanders.

"Skipper", an FPV company commander in Ukraine's 413th Raid Unmanned Systems Regiment, has described destroying a Russian UR-77 mine-clearing vehicle with drones during the 2023 counteroffensive as the strike he is proudest of, according to Army TV.

The UR-77, nicknamed "Zmiy Horynych" after a fire-breathing serpent of Slavic folklore, carries a rocket-fired line charge to blow paths through minefields, as per Militarnyi. Each charge carries more than two tons of explosives, which is why a cheap FPV hit can trigger a blast far larger than the drone itself.

"It exploded so hard that I thought it was a small nuclear blast. There are more than two tons of plastic explosive inside, and when it went off after the second hit, it was something unbelievable," Skipper says.

Skipper joined the army at the start of the full-scale invasion and moved from infantry and aerial reconnaissance to commanding an FPV unit. His regiment now operates on the Zaporizhzhia front, where FPV drones conduct combat missions.

From sailing yachts to FPV drones

In civilian life, Skipper was a sailing instructor, and he says the sport partly helps in military work, especially his knowledge of navigation and radio communication. He is convinced that a technological edge can be one of the keys to victory.

He counts the UR-77 strike among his unit's early work, from a time when few Ukrainian units were using FPV drones at all, he says. The hit came during hard fighting in the counteroffensive, when his crews were among the first to work the FPV niche.

Russia turns a mine-clearer into a wrecking tool

The UR-77 was built in the 1970s for a different war, one of fast tank thrusts that needed enemy minefields cleared quickly. Its base rides on the chassis of the 2S1 Gvozdika self-propelled howitzer, and its charge can cut a lane six meters wide, with some anti-personnel mines detonated across a band up to 15 meters wide.

Modern combat changed that role. The classic mine-clearing use remains, but Russia now more often turns these machines on Ukrainian fortifications, using the line charge to flatten defenses rather than open a path.
