Ukraine operates four nuclear power plants with 15 reactors located in Volhynia and South Ukraine.[28] The total installed nuclear power capacity is over 13 GWe, ranking 7th in the world in 2020.[29] Energoatom, a Ukrainian state enterprise, operates all four active nuclear power stations in Ukraine.[30] In 2019, nuclear power supplied over 20% of Ukraine's energy.[31]
70TWh of electricity generation was nuclear in 2020, which was over 50%.[31] This was the 3rd largest share, only France and Slovakia had a higher share. The largest nuclear power plant in Europe is in Ukraine.
The 1986 Chernobyl disaster in Northern Ukraine was the world's most severe nuclear accident.
Lack of coal for Ukraine's coal-fired power stations due to the War in Donbass and a shut down of one of the six reactors of the Zaporizhzhia Nuclear Power Plant led to rolling blackouts throughout the country in December 2014.[32][33][34][35][36]
