Russia is planning a winter strike campaign involving up to 1,000 missiles, drones, and bombs targeting, among other facilities, electrical substations, hydroelectric and thermal power plants, and boiler houses. The information is contained in a document that, according to sources cited by The New York Times, Ukraine's Energy Minister Denys Shmyhal presented as an intercepted Russian plan to destroy energy infrastructure systematically. The newspaper reported on 2 October.

Russia has been striking critical infrastructure across Ukraine since the beginning of its full-scale invasion. Such attacks have become particularly frequent ahead of and during winter. Ukraine's recent battlefield gains may have prompted Putin to reconsider his strategy and attempt to force Ukraine to surrender through winter strikes, analysts at the Institute for the Study of War (ISW) suggest. Russia's reported plans to attack Ukraine's energy, water supply, and sewage systems could threaten the basic living conditions of millions of people. Such strikes could increase pressure on civilians and the Ukrainian economy while forcing the state to divert more resources to emergency infrastructure repairs instead of defense needs.

The New York Times was unable to verify the document's authenticity independently, but noted that it was written in Russian and dated August.

A representative of Ukraine's defense-industrial sector who has reviewed the document believes it is more of a calculation than a finalized Russian military operations plan, according to Schemes, an investigative journalism project by Radio Free Europe/Radio Liberty (RFE/RL), in a report published on 8 October.

60 targets: how Russia could attack Ukraine's critical infrastructure

The document outlines how many missiles, drones, and bombs Russia would need to deprive Kyiv, Kharkiv, and Odesa of electricity, heating, water, and sewage services, Radio Liberty reported on 9 October. The document's full list of priority cities also includes Dnipro, Zaporizhzhia, Mykolaiv, Kherson, Poltava, Chernihiv, Kryvyi Rih, Cherkasy, Kropyvnytskyi, Lviv, Vinnytsia, and Ivano-Frankivsk.

According to the document, Russia plans to begin by attacking substations near Ukraine's western border, through which the country receives electricity from Europe. Hydroelectric power plants could be targeted next, followed by facilities intended to shut down Ukraine's three operational nuclear power plants, Radio Liberty reports. The document lists a total of 60 key targets.

According to Schemes, the document states that Russia would need up to 770 Molniya and Geran drones, Dan-T/Banderol missile-drones, 170 FAB guided aerial bombs, and 75 Kinzhal and Iskander-M ballistic missiles to carry out the attacks.

Sewage systems could become Russia's next target

The document devotes particular attention to water supply and wastewater systems. These include pumping stations, treatment facilities, and other infrastructure essential for cities to provide residents with water and dispose of wastewater.

Russia has not previously attacked such facilities on a similar scale, The New York Times notes.

Preparing for possible attacks on water supply and sewage systems is significantly more difficult than protecting energy infrastructure, Oleh Popenko, head of the Ukrainian Union of Utility Services Consumers, told Current Time, RFE/RL's Russian-language network.

“Sewage is a very complex system. There are specific challenges: where to discharge wastewater, how to organize treatment facilities, and so on. Some work is also underway in this sector, but it will be much more difficult here than with district heating utilities,” Popenko says.

Creating alternative routes in case sewage pumping stations are destroyed is an expensive and technically challenging task, he adds. Such construction could cost billions of hryvnias.

The priority is to equip water utilities with backup power sources so they can continue operating during power outages. However, if Russian strikes damage the sewage system itself, resolving the problem quickly will be much more difficult, Popenko believes. Specific solutions, including wastewater disposal and the operation of treatment facilities, will have to be determined according to the extent of the damage.

Sewage pumping stations play a particularly important role. They pump wastewater onward for disposal and treatment. If such a station is put out of operation by a strike, the city needs an alternative way to divert wastewater while the damaged facility is being repaired, Popenko says. Bypass pipes or channels could be installed for this purpose, but setting up such a system during wartime is far from easy.

Air defenses remain crucial to Ukraine's winter preparations

Preparations for winter are underway, but protection for energy infrastructure remains inadequate, Popenko believes. The main concern is large substations that transmit electricity from nuclear power plants and distribute electricity imported from Europe.

At the same time, some protective measures are already proving effective. Despite drone attacks over two days, one of Kyiv's substations withstood the strikes, and the city did not lose power, although scheduled outages were in effect, the expert says.

Popenko considers a repeat of last winter's scenario, when parts of Kyiv went without heating for weeks, entirely possible. Russian forces continue to attack energy facilities, and in his assessment, strengthening air defenses in Kyiv is the only way to protect its combined heat and power (CHP) plants from large-scale attacks.

“There are no other ways — for example, building some sarcophagi around CHPs or constructing shelters — because Russia can destroy these facilities again through massive strikes. And then the city risks being left 50–60% without heat,” Popenko believes.

Residents are also preparing for winter, but their options vary, he says. Some homeowners' associations participate in government programs to insulate apartment buildings and purchase backup power supplies for elevators and pumping stations. Owners of private houses are buying generators, among other measures. However, such equipment and preparations require substantial funds, meaning not everyone can afford them, he notes.

Ukraine has already experienced prolonged power outages during previous winters, particularly in 2022 and 2023. At the time, some regions went without electricity for 18–20 hours a day, the expert says. This experience may help people prepare for possible disruptions, but it does not eliminate the risk of further attacks and infrastructure damage.

Russian drones hit Ukraine's power grid, warehouses, a food warehouse, a home-improvement store, and a farm overnight on 9 October, Ukrainian officials and emergency services reported. The strikes triggered emergency power cuts in Kyiv and other regions and killed at least three people across the country.

As Russia continues its daily terror attacks, it has likely begun its winter strike campaign early, aiming to make civilian life in Ukraine unbearable, ISW assessed. Those strikes now reach beyond the grid to the businesses that store and sell goods, adding to damage Ukraine's Economy Ministry expects to reach up to $10 billion this year.

Power cut in Kyiv and other regions

Russia launched 136 drones overnight, 93 of them jet-powered, Ukraine's Air Force said. Air defenses downed or suppressed 114. Drones hit eight locations, and debris fell at seven more.

DTEK, Ukraine's largest private energy company, introduced emergency power cuts on Kyiv's right bank and in the Bucha and Vyshhorod districts on the grid operator's orders. Ukrenergo, the national grid operator, imposed emergency outages in some regions, citing the strain Russian attacks put on the system. Planned schedules were suspended there. Hourly cuts across parts of Ukraine had already been set for the whole day.

The cuts came a day after a Russian strike knocked out several grid elements supplying Kyiv, leaving many consumers without power. Russia has sharply stepped up attacks on Ukraine's energy system in recent weeks, deliberately targeting power lines and transformers, Ukraine's Energy Ministry said.

Warehouses and a store

In the Bucha district of Kyiv Oblast, Russia hit warehouses and injured three people, Ukraine's State Emergency Service said. One was hospitalized. Rescuers were searching for a woman who may be under the rubble.

In Odesa, a strike damaged the roof of a warehouse storing food and started a fire, the region's emergency service reported. In the south of the oblast, Russia damaged buildings at holiday resorts and destroyed a café.

Near Chernihiv, Russia hit a site just outside the city after 03:00, the city council said. A Suspilne correspondent at the scene reported that a drone hit the Epicenter store, part of a large Ukrainian home-improvement chain. Russian forces also struck a farm in the Kulykivka community. No one was hurt in Chernihiv Oblast.

Russia has already destroyed more than two-fifths of Ukraine's modern warehouse space.

Three killed overnight

In Zaporizhzhia, Russia struck near an apartment building, killing a man, the Zaporizhzhia Oblast administration said. The number of injured rose to nine, including a 14-year-old girl, regional prosecutors said. One strike landed near an after-school education center.

In Ivano-Frankivsk, falling drone debris started a fire, and a man born in 1959 was killed, Ivano-Frankivsk Oblast head Svitlana Onyshchuk said.

In Shyroka Balka, Kherson Oblast, a Russian drone dropped explosives on a house at about 06:20, killing a 74-year-old woman and injuring a 68-year-old man, regional prosecutors reported.

Russia injured three women in a Kharkiv suburb, Kharkiv Oblast head Oleh Syniehubov said. In the Nikopol district, a 24-year-old woman was injured, Dnipropetrovsk Oblast head Oleksandr Hanzha said.
