While Ukraine’s energy system, which had a pre-war generation capacity of 60 gigawatts, scrambles to keep the lights on, grid operators are also looking past the next drone swarm, pushing to diversify the country’s energy sources, says Lars Handrich, a German energy expert who works closely with Ukraine.

The plan is to replace the bulky thermal plants and centralized grid, which are vulnerable to drone and other attacks, with distributed renewables and modestly sized gas-fired plants that make less attractive targets for incoming fire. According to estimates from the Solar Energy Association of Ukraine, the nation installed at least 1.5 gigawatts of new solar generation in 2025—enough to power roughly 1.1 million homes—and grid operators intend to almost double the country’s renewable energy production over the next four years.

Ukraine is revamping its power sector as rapidly as it can, not for climate protection but for energy security.
