Zaporizhzhia Nuclear Power Plant in the context of Kakhovka Reservoir

The ongoing military occupation of Ukraine's Zaporizhzhia Oblast (Ukrainian: Запорізька область, romanized: Zaporiz'ka oblast') began after Russian forces launched an invasion of mainland Ukraine out of Crimea on 24 February 2022. Russian-controlled parts of the oblast were administered by a Russian military-civilian administration until 30 September 2022, when they were illegally annexed to become an internationally unrecognized federal subject of Russia.

On 25 February, the city of Melitopol fell under Russian control, followed by Berdiansk the next day. Russian forces besieged the city of Enerhodar, home of the Zaporizhzhia Nuclear Power Plant, then captured it on 4 March. The oblast's capital city of Zaporizhzhia, however, remains under Ukrainian government control.

On 4 March 2022, a military engagement took place between the Russian Armed Forces and the Armed Forces of Ukraine over the city of Enerhodar in Zaporizhzhia Oblast, on the southern front of the Russian invasion of Ukraine. Enerhodar is the location of the Zaporizhzhia Nuclear Power Plant, which generates nearly half of the country's electricity derived from nuclear power and more than a fifth of total electricity generated in Ukraine, as well as a nearby thermal power station.

Ukraine operates four nuclear power plants with 15 reactors located in Volhynia and South Ukraine. The total installed nuclear power capacity is over 13 GWe, ranking 7th in the world in 2020. Energoatom, a Ukrainian state enterprise, operates all four active nuclear power stations in Ukraine.In 2019, nuclear power supplied over 20% of Ukraine's energy.

In 2021, Ukraine's nuclear reactors produced 81 TWh — over 55% of its total electricity generation, and the second-highest share in the world, behind only France. The Zaporizhzhia Nuclear Power Plant, the largest nuclear power plant in Europe, is in Ukraine.
