Russia has launched one of its most punishing air offensives of the war, striking Ukraine’s power grid and plunging large parts of the country into darkness and cold. The latest wave of missiles and drones has cut electricity to more than a million people, disrupted heating in the capital, and deepened a humanitarian crisis as winter temperatures fall below freezing. The scale and timing of the assault underline how energy has become a central battlefield, with civilians bearing the brunt.
Officials describe a deliberate effort to break Ukraine’s resilience by targeting the systems that keep homes warm, water running, and hospitals functioning. The strikes have hit an already weakened grid that has lost a significant share of its generating capacity over the past two years, forcing authorities to rely on emergency repairs, rolling blackouts, and foreign aid to keep the lights on.
Coordinated strikes and a vulnerable grid
Ukrainian authorities say the latest barrage was a coordinated attempt by Russia to overwhelm air defenses and cripple key nodes of the national power system. The attack focused on the capital and several regions in the north and east, with Prime Minister Yulia Svyrydenko stating that Russia targeted them in a concentrated overnight assault. The pattern fits a broader strategy in which Russia has repeatedly used long-range weapons to hit power plants, substations, and transmission lines far from the front line.
Energy officials report that the latest wave left more than 1.2 million homes without electricity across the country, with one assessment noting that 1.2 million homes lost power in a single night. Another analysis of the overnight missile and drone attacks describes Russian Air Attacks, underscoring how a single operation can affect more than 1.2 M people at once. Earlier assessments of the grid’s condition show why the impact is so severe, with experts noting that in 2024 alone Ukraine lost about to missile and drone attacks, roughly one third of its pre war conventional power.
Kyiv in the dark and the human cost of winter outages
The capital has once again become a symbol of the country’s energy ordeal. Local authorities report that an energy company, Energy DTEK, saw 88,000 households in Kyiv cut off as the latest strikes damaged infrastructure feeding residential districts. A separate humanitarian tally notes that nearly 6,000 buildings in Kyiv were left without heat and more than 800,000 people lost power, while across Ukraine, around 1.2 m households were affected, with the figures cited as nearly 6,000, 800,000. These numbers translate into apartment blocks without radiators, schools forced to close, and families relying on candles and battery-powered lamps.
The humanitarian stakes are heightened by the weather. In the capital, officials say temperatures have dropped to around minus 10 degrees Celsius. The city’s central heating network has also been disrupted, with an account of the overnight barrage stating that the strikes disrupted Kyiv’s central heating and left some residents without heat or water. For vulnerable residents, including the elderly and those in high-rise buildings, local officials warn that prolonged outages can quickly become life-threatening.
International condemnation and emergency support
The latest attacks have drawn sharp criticism from international institutions that see a pattern of deliberate targeting of civilian infrastructure. The UN rights chief has described the situation as “Cold and dark,” condemning Russian strikes that systematically degrade the power grid and leave civilians exposed in winter. Human rights officials link the current wave to similar strikes earlier in the month, arguing that repeated attacks on energy facilities raise serious concerns under international humanitarian law, which requires distinction between military and civilian targets.
European governments are trying to blunt the impact by rushing equipment to keep essential services running. The European Union has announced that it will send hundreds more generators to Ukraine, aiming to power hospitals, shelters, and water systems where grid supply has failed. Officials in Brussels say the move responds to Russian strikes that have cut electricity and heating and continue to injure civilians across Ukraine. Yet even as aid flows, energy experts caution that generators are a stopgap, not a substitute for a functioning grid, and that fuel, maintenance, and security for these units will pose their own challenges in the months ahead.
Energy warfare, stalled diplomacy, and a long winter ahead
The assault on Ukraine’s power system is not an isolated episode but part of a longer campaign to use energy as a weapon. Analysts tracking the conflict note that earlier in the war, Paris based International experts estimated that Ukraine had already lost about 70% of its thermal generation capacity by the spring due to Russian strikes or occupation, a staggering figure that left the grid heavily reliant on remaining plants and imports. A separate assessment of the latest offensive notes that, consequently, Centrenergo, the state-owned company that once operated three large thermal units, has seen all of them either completely destroyed or brought under Russian control. These structural losses mean that every new strike has a compounding effect, eroding redundancy and making blackouts harder to avoid.
The timing of the latest barrage has also complicated diplomatic efforts. As Ukrainian and Russian delegations met in the UAE for talks brokered by the United States, reports noted that on the eve of the second day, Russian attacks cut about a million people from power in sub zero temperatures. The discussions in the UAE ended with no breakthrough, and negotiators left with the knowledge that the war’s energy front is intensifying rather than easing. For many in Ukraine, the message is clear: the coming months will demand not only military resilience but also the ability to endure life in the cold and dark while the country fights to keep its grid alive.
