When Russian air strikes knocked out Ukrainian power plants earlier this year, most of Mykolaiv lost the ability to pump drinking water. In an easterly suburb, however, water continued to flow from kitchen taps—powered by a small off-grid solar field and battery system funded by the Danish government. The two elevated arrays run an underground pump on the premises. "There's just enough sun [in January] to make it work," says Olena Kondratiuk, project manager of Ecoclub, a non-profit that helps municipalities obtain renewables.
Mykolaiv, only 60 kilometres from Russian-occupied territory, was heavily bombardment in 2022. The central water supply system was impaired, leaving roughly half the city without regularly flowing water. Until the solar park commenced operation, residents accessed salty estuary water or queued for mobile public tanks. Five solar-powered desalination systems elsewhere in the city turn saline water into drinking water when the sun shines; at night and on cloudy days, they depend on the central grid—if it is operating. The system can supply 250,000 residents with 1.2 million litres of drinking water a day, making it one of the largest of its kind in Europe.
The article argues that Ukraine's experience illustrates a broader vulnerability of centralized energy. Russia has relentlessly targeted thermal plants, transmission grids, and substations, with economists estimating total energy-sector damage above $56 billion. US environmentalist Bill McKibben writes that centralized, complex facilities are "sitting ducks for drone attack," while smaller, scattered generation with batteries is harder to strafe and quicker to repair. Jeff Oatham of DTEK, Ukraine's largest energy investor, puts it quantitatively: a coal power station is a single target one missile could take out; "you would need around 40 missiles to do the equivalent amount of capacity damage at a wind farm."
Ukraine's energy analysts describe the shift as coldly calculated security policy, not climate symbolism. "Ukraine's energy transition is not a slogan," says Levgeniia Kopytsia of the Institute for Climate Protection, Energy and Mobility. "It's a security-driven transformation, unfolding under extreme constraints. It priorities decentralization, flexibility, and speed of recovery." The IEA reported last summer that Ukraine made "strong strides" in rebuilding resilience, with rooftop solar, small-scale utility PV, and local storage leading the rollout.
Storage deployment has accelerated dramatically. The national grid operator invested in half a gigawatt of storage capacity last year—just under a quarter of Germany's total supply, yet deployed in roughly six months compared with the two years typical in Europe, according to the Financial Times as cited by the article.
The piece also notes limits. Ukraine still requires a centralized grid for larger supply options such as gas turbines and wind parks, and those transmission links remain Russian targets. The article says Ukrainians are putting substations underground, as they now do with schools. It also acknowledges that no public figures for energy production are available for security reasons, and that the country envisions diesel generators, biomass facilities, and small gas turbines alongside renewables as part of its scattered supply mix.
One meaningful gap the article does not fill is cost. It quotes Andriy Martynyuk, a Ukrainian energy expert, noting that rooftop solar uptake is largely a grassroots phenomenon, and that demand could rise further when state subsidies for conventional energy fall away—but it provides no installation-cost or levelized-cost comparison between distributed solar and centralized alternatives.
