(KYIV, UKRAINE) – Ukraine’s nuclear power plants generated 26.82 billion kilowatt hours of electricity in the first half of 2026, according to state operator Energoatom. This represents an increase of 163.1 million kilowatt hours compared with the same period a year earlier.
Nuclear generation accounts for the largest share of electricity in Ukraine’s energy balance. Data published by the National Commission for State Regulation in Energy and Public Utilities shows that between 2019 and 2025, the share of electricity produced by nuclear plants exceeded 67 percent during certain periods.
The operator’s production figures come as the government sets out its long range plans for the sector. President Volodymyr Zelensky has described nuclear generation as a serious foundation for Ukrainian energy and has indicated that this area will be developed further.
First Deputy Prime Minister and Energy Minister Denys Shmyhal has identified the expansion of nuclear capacity as one of the key tasks ahead. The aim is to reach 25 gigawatts of nominal nuclear capacity by 2050, which would form the basis of a new energy architecture for the country.
Energoatom has not provided a breakdown of output by individual plant or reactor type. The total production figure covers all Ukrainian nuclear facilities operating during the January to June period.
The company did not disclose financial results or tax contributions in this statement. However, earlier reports from Energoatom indicated that it had paid nearly UAH 35 billion in taxes and dividends since the start of the year. At current exchange rates, this equates to approximately USD 945 million or GBP 730 million.
The nuclear sector’s performance is closely watched given its importance to domestic power supply and export capacity. Ukraine has relied on nuclear energy to maintain grid stability, particularly during periods when thermal and hydro generation have been affected by wartime damage to infrastructure.
