As of August 2026, the Ukrainian energy system demonstrates a stable generation structure, where nuclear power continues to play a dominant role. The National Commission for State Regulation of Energy and Public Utilities (NERC) has analyzed data for the reporting period ending in December 2025. According to these figures, nuclear power plants provided the overwhelming majority of generation — 62.7% of the total electricity production in the country. ### Generation Structure: Nuclear vs. Traditional Sources A detailed analysis of the statistics for December 2025 shows that nuclear generation remains the foundation of Ukraine's energy system. In second place by generation volume are combined heat and power plants (CHPs), providing 13.3% of the total volume. Traditional thermal power plants (TPPs) took third place with a share of 12.6%. Hydropower, including hydroelectric power plants (HPPs), accounted for 5.7% of production, while pumped-storage hydroelectric power plants (PSHPPs) accounted for 1.8%. The share of renewable energy sources (RES) was 3.8%. These figures confirm that, despite the active development of alternative energy, the base load still falls on nuclear reactors. ### Diversification of Market Participants An important aspect revealed during NERC's monitoring is the significant difference between the generation structure and the trading structure. While electricity production is concentrated in the hands of major players, primarily Energoatom, the sales and trading market demonstrates a high degree of diversification. As of the beginning of 2025, more than 500 active participants operated on the bilateral contracts market. The intraday market united more than 200 companies, and the balancing market — over 30 participants. This indicates that the Ukrainian electricity market is a complex ecosystem with a wide circle of commercial players. ### Data Transparency and New Analysis Tools The regulator has taken steps to increase industry transparency by opening access to detailed statistics on trading volumes, weighted average prices, liquidity, and market concentration levels. Publishing this data in an open data format allows not only government bodies but also researchers and the public to see the full picture: who exactly produces energy, who trades it, and what the import and export volumes are. NERC emphasizes that covering the period from the launch of the new market model makes it possible to assess not only price fluctuations but also structural changes in the industry. ### Contradictory Data In the context of analyzing the market situation, it is worth noting the difference in approaches to assessing stability. On the one hand, the regulator (NERC) claims an increase in the stability of the energy system due to the revision of price caps, which, in their opinion, helped overcome the winter deficit. On the other hand, market participants sometimes point to the difficulty of forecasting prices due to high volatility, despite the existence of limit values. Furthermore, in mid-July 2026, the Ukrainian Energy Exchange (UEX) officially did not detect signs of manipulation during the auction for the sale of electricity by Energoatom, although the expert community periodically discusses the need to tighten control over large deals in conditions of deficit. ## 🔍 Fact-Check Verification - [NERC raised price caps on the electricity market by April: details](https://delo.ua/ru/news/nkreku-k-aprelyu-povysila-prais-kepy-na-rynke-elektroenergii-detali-458519/) - Подтверждает действия регулятора по регулированию цен. - [Revision of price caps strengthened energy system stability during the winter deficit – NERC](https://www.obozrevatel.com/ekonomika-glavnaya/peresmotr-prajs-kepov-usilil-ustojchivost-energosistemyi-v-period-zimnego-defitsita-nkreku.htm) - Подтверждает заявления НКРЭКУ об устойчивости системы. - [NERC set new maximum prices on the electricity market from May 1](https://ukranews.com/news/1148114-nkreku-ustanovila-s-1-maya-novye-predelnye-tseny-na-rynke-elektroenergii) - Подтверждено по источнику ukranews.com ## ❓ FAQ ### Q: What is the share of nuclear power in Ukraine's electricity production? **A:** According to NERC data for December 2025, nuclear power plants provided 62.7% of total electricity production. ### Q: How many companies operate in the Ukrainian electricity market? **A:** More than 500 active participants operate on the bilateral contracts market, and more than 200 on the intraday market. ### Q: What is the share of renewable energy sources (RES)? **A:** The share of renewable energy sources was 3.8% of the total production volume.
