How the structure of electricity generation in Ukraine has changed over the years of our licences: from 2018 to today.
Dynamics by year
| Year | Nuclear, % | Thermal, % | Hydro, % | Block stations, % | Renewables, % | Total, TWh | Structure |
|---|---|---|---|---|---|---|---|
| 2018 | 53.0 | 36.9 | 7.5 | 0.9 | 1.7 | — | |
| 2019 | 53.9 | 36.3 | 5.1 | 1.1 | 3.6 | 154.0 | |
| 2020 | 51.2 | 35.2 | 5.1 | 1.2 | 7.3 | 148.8 | |
| 2021 | 55.1 | 29.3 | 6.7 | 1.0 | 8.0 | 156.6 | |
| 2022* | 55 | 28 | 10 | — | 6 | ≈ 103 | |
| 2023* | 50 | 33 | 10 | — | 7 | ≈ 103 |
What the data show
Nuclear is the backbone
Nuclear plants produced more than half of electricity throughout the period (51–55% in 2018–2021). In December 2025, per NEURC, their share reached about 62.7%.
Thermal generation is shrinking
The share of thermal plants fell from almost 37% in 2018 to about 29% in 2021. At the end of 2025 thermal plants and CHPs together produced roughly a quarter.
Rapid growth of renewables
The renewables share rose from 1.7% in 2018 to 8% in 2021. Per NEURC, renewables provided about 11% of generation in 2025, of which about 78% was solar.
2024–2025
Because of attacks on the power system and strong seasonal swings, the generation mix became unstable: nuclear share rises in winter (above 58%) and falls to 43–47% in summer when solar plants work, with renewables at about 19% in some months. Annual percentages for these years differ depending on methodology, so we do not show them in the table. Current monthly data are published by NEURC and Ukrenergo.
