Ukraine is revamping its power sector as rapidly as it can, not for climate protection but for energy security. “Ukraine’s energy transition is not a slogan,” says Ievgeniia Kopytsia, a Ukrainian energy analyst at the Institute for Climate Protection, Energy and Mobility. “Since the full-scale invasion, Ukraine has added over 3 gigawatts of new renewable energy capacity. It’s a security-driven transformation, unfolding under extreme constraints, that prioritizes decentralization, flexibility, and speed of recovery.”
Wind and solar arrays with independent transmission lines are scattered over the landscape, which makes them harder to hit and easier to repair. “A coal power station [is] a large single target that a single missile could take out,” says Jeff Oatham of DTEK, Ukraine’s largest energy company and its largest private energy investor. “You would need around 40 missiles to do the equivalent amount of capacity damage at a wind farm.”
Solar, too, makes an unattractive target. “Attacking decentralized solar power installations is not economically rational,” says Ukrainian energy expert Olena Kondratiuk. “Missiles and drones are expensive, and significantly disrupting such systems would require a large number of strikes, while the overall impact on the energy system would remain limited.” Both solar and wind parks can function even when parts of them are out of operation.

European countries are bankrolling most of Ukraine’s energy makeover, including all of the Mykolaiv solar installations. West of Kyiv, the city of Zhytomyr has plans to run entirely on renewables by 2050 with the help of the Rebuild Ukraine initiative, which is largely European funded. And in the Kyiv region and beyond, solar systems supported by the Solar Supports Ukraine program are keeping schools open during blackouts. A self-financed exception: Before the war began, the Sunny City cooperative in Slavutych, a town near the Belarus border, crowdfunded to create a solar power plant on the roofs of three municipal buildings.

Some self-sustaining energy zones combine renewables with conventional energy. The central Ukrainian city of Vinnytsia, for example, boasts five microgrids that combine local generation, including solar, gas, and hydroelectric power, with energy storage systems. Five major wind farms will join the energy mix in the next two years. In Khmelnytskyi, the national university’s 4,400-kilowatt microgrid includes a natural gas-fired cogeneration unit (it produces both electricity and heat), a 264-kilowatt solar array, a diesel-powered plant, and a gas-fired boiler house, which generates heat.

Before Russia seized territory that hosted more than half of Ukraine’s wind power capacity in 2014 and 2022, including major wind farms on the Sea of Azov coast, Ukraine had 34 wind parks, comprised of nearly 700 turbines. Since wind generation is so central to its decentralized energy strategy, Ukraine has strived to increase wind generation even in the midst of Russian attacks.
Just 65 miles from the front, DTEK is installing the 500-megawatt Tyligulska Wind Power Plant, the first wind park ever built in a war zone. It is a crucial source of electricity in southern Ukraine and will supply 900,000 households when it’s finished. The country currently has 7 gigawatts of wind power in the pipeline that could be installed this year, according to Andriy Konechenkov, of the Ukrainian Wind Energy Association, should conditions on the ground allow it. The new turbines would more than triple the country’s current wind-power capacity.
While the war has sidelined the rollout of utility-scale wind farms, solar installations atop households, businesses, and public institutions have continued at an unprecedented rate. Ukraine’s YASNO utility, which supplies electricity and gas to millions of Ukrainians, says its customers are snapping up the solar and storage packages that it offers. On sunny days, Ukraine even boasts energy surpluses.

“Individual consumers want to get off the grid any way that they can,” explains Andriy Martynyuk of Ecoclub, a Ukraine-based NGO that helps communities develop renewables. “It’s largely a grassroots phenomenon and a bit chaotic now,” he says. But Martynyuk expects the demand for renewables will further surge when state subsidies for fossil energy, which have priced Ukrainian energy significantly below market rates, are eventually phased out.
This boom, of course, begs for storage options, and there, too, Ukraine has moved quickly. In 2024 and 2025, the country’s national grid operator invested in half a gigawatt of storage capacity — an impressive amount according to experts, who note that it is just under a quarter of Germany’s total storage supply. The battery projects that in Europe take two years to roll out, the Financial Timesreports, take just six months in Ukraine.

In terms of a new, cutting-edge distributed energy system, Ukraine may be racing forward with the zeal of a new convert, but even the planned rollout of renewables in 2026 won’t keep most of the Ukrainian population safe from Russia’s depredations next winter. Wartime Ukraine has the will but not the financial resources to revamp its energy production on its own. The nation’s largest donor, the E.U., is already contributing nearly $200 billion to Ukraine’s budget for military expenditures and humanitarian aid, including energy. The speed with which Ukraine blankets its territory with distributed energy systems could make the difference between surviving another punishing winter — or succumbing to its cruelty.
