Russia has a new warhead for its drones, and it is built to cut down power lines. For the first time, a jet drone has carried a shaped "cumulative-cutting" charge designed to sever high-voltage pylons and iron bridges, Serhii Beskrestnov, presidential adviser, known as Flash, said, as Russia opened its heaviest assault on Ukraine's power grid since last winter.

On 30 September, Russia launched its massed fall-winter campaign on Ukraine's energy infrastructure since the last heating season, hitting power sites across 11 regions overnight with missiles and drones, Prime Minister Serhii Koretskyi said.

The new warhead fits the aim: Flash says it is meant to bring down the high-voltage lines that carry the country's electricity. And Ukraine enters the winter exposed, with its energy resilience plans less than half complete.

A new charge targets the pylons

The device, which Flash calls a cumulative-cutting special load, is designed specifically to bring down high-voltage pylons and iron bridge structures.

"It consists of a main charge weighing 40 kilograms and four strike modules," he says.

In his reading, Russia intends to go after the major transmission lines that move power across the country, the backbone of the grid, rather than the substations it has struck before.

The campaign builds toward November

On 29 September, two senior Ukrainian officials told The Economist that Russia launched a three-part campaign of attacks on Kyiv, combining massive bombardments, sabotage, and the creation of political chaos. These efforts aimed at destabilizing the Ukrainian capital would peak by November, they said.

According to a representative of the Security Service of Ukraine, Russia has "thousands" of drones in its arsenal and is simultaneously expanding its stockpile of ballistic missiles. The plan is to "deploy the entire arsenal over the next two months," given that Ukraine lacks an effective weapon against jet-powered drones.

Russian strikes cut power to nearly a million Ukrainian families across four oblasts last week. Ukraine's largest private energy company, DTEK, brought it back, fully or partly restoring electricity to 596 settlements in Donetsk, Odesa, Dnipropetrovsk, and Kyiv oblasts between 31 August and 6 September, the company said.

Russia is hammering Ukraine's power grid again as the cold season nears, and the country's winter-resilience plans were less than half complete at the start of September.

Odesa and Donetsk absorb the worst

Most of the week's work was in Odesa Oblast, which Russia has been striking without pause. Ukrainian crews there returned power to more than 366,000 families, DTEK said.

Much of that damage followed a massed missile-and-drone strike on the region's main energy facilities on 2 September, after which national operator Ukrenergo imposed temporary grid limits to keep damaged equipment from overloading.

Donetsk Oblast came close behind, with power restored to nearly 360,000 homes despite what the company called an extremely difficult situation for its repair teams. In Dnipropetrovsk Oblast, crews reconnected almost 172,000 homes, and in Kyiv Oblast nearly 9,000 more.

Strikes keep cutting the grid

The reconnections are happening under continued fire. Russia keeps attacking energy sites in Odesa and Dnipropetrovsk oblasts, damaging lines faster than they can be fully secured. DTEK crews can only begin repairs once the military and emergency services have cleared access to the damaged equipment.

"Russia keeps attacking our energy system. Despite everything, we keep working and restoring power — now on the 1,657th day," said Alina Bondarenko, chief executive of DTEK Grids.

Winter sharpens the threat

The timing is the danger. Ukraine has until the heating season to shore up a grid that Russia has spent the war trying to break.

This year's attacks have again concentrated on the energy system as temperatures start to fall.

Kyiv is building reserves of food and drinking water to help residents during prolonged power outages and other emergencies, the Kyiv City Council said on 7 September.

The preparations come as Russia continues to target Ukraine’s critical infrastructure and food supply chains, while Ukrainian officials warn that water systems could also come under attack. Kyiv is therefore preparing for a broader range of disruptions this winter, not just power outages.

The city is preparing the reserves ahead of the 2026–2027 fall and winter season, with priority given to low-income residents and people facing difficult circumstances.

The supplies will also be available at Points of Invincibility, emergency support centers set up to provide basic services during prolonged blackouts, for people affected by emergencies, and for workers involved in emergency and other urgent response operations.

Kyiv prepares for attacks on food and water supplies as Russia makes air attacks harder to stop

Russia has increasingly targeted infrastructure connected to Ukraine’s food supply in recent months. Russian strikes have hit food warehouses and distribution facilities around Kyiv, contributing to shortages and periods of empty supermarket shelves in the capital and other parts of the country.

Ukrainian officials have also warned that Russia could target water infrastructure as part of its attacks on critical civilian systems, raising concerns about access to drinking water during prolonged disruptions.

This year, the threat is particularly acute as Russia has expanded its use of ballistic missiles and introduced faster, jet-powered Geran drones that are harder for Ukraine to intercept. Ballistic missiles can only be reliably intercepted by a limited number of air defense systems, while the faster drones reduce the time available to detect and engage them.

Kyiv prepares for another difficult winter

Russia's strikes have repeatedly targeted Ukraine's energy infrastructure during previous winters, causing extended blackouts and disruptions to heating and other essential services.

Kyiv is now preparing for the possibility that attacks could again leave residents without electricity or access to essential supplies for extended periods.

Kyiv says food supply remains stable, for now

Oleh Kuіavskyi, deputy head of the Kyiv City State Administration, said the city's preparations are focused not only on accumulating supplies but also on ensuring they can quickly reach people who need them.

“Food security in the capital is not only about having the necessary reserves, but also a clear system for their distribution and delivery to those who need help most,” Kuіavskyi said, according to the Kyiv City Council.

He said Kyiv's consumer market remains stable and predictable, while the city continues to hold agricultural food fairs across its districts to help maintain access to basic food products.

Reserves could feed 25,000 people

According to the city council, Kyiv has already formed and is maintaining reserves of key food products for use if the energy system comes under severe strain.

With support from charitable and civic organizations, the city can organize hot meals for up to 25,000 people, officials said.

The city's Department of Industry and Entrepreneurship Development also plans to purchase another 20,000 food packages for use during emergencies.

The reserves are being coordinated through Kyiv's Humanitarian Headquarters, established in February 2022. The body coordinates the city administration, district administrations, municipal companies, charities, and donors, including the accounting and distribution of emergency resources.
