War damage to Ukraine’s power system has increased the country’s reliance on nuclear energy
The Facts
- Since Russia’s 2022 invasion, Ukraine has relied more heavily on nuclear power because repeated attacks damaged other parts of its electricity system.
- Before the war, Ukraine operated four nuclear power plants with a total of 15 power units/reactors.
- Before the war, nuclear generation accounted for more than half of Ukraine’s electricity production.
- During the war, Energoatom said nuclear power’s share of Ukraine’s electricity generation rose to about 70%.
- The Zaporizhzhia nuclear power plant is Ukraine’s largest nuclear station and was occupied by Russian forces in 2022.
- The Zaporizhzhia plant was later shut down after its occupation.

How left and right read it
Russia’s attacks have pushed Ukraine into even greater dependence on nuclear power by damaging other parts of the electricity system. Nuclear energy already provided more than half of the country’s electricity before the war, and Energoatom says that share has risen to about 70% even after Ukraine lost access to its largest plant, Zaporizhzhia, which was occupied in 2022 and later shut down.
The war has shown how essential dependable baseload power is: even before the invasion, Ukraine’s four nuclear plants and 15 reactors supplied more than half of its electricity, and Energoatom says that share has climbed to about 70% after attacks damaged other generation. At the same time, the occupation and shutdown of Zaporizhzhia highlight how critical major energy infrastructure is in wartime.
