140 According to the National Bank of Ukraine, the electricity deficit should decrease to 3% by 2026. This is due to the implementation of reforms and the attraction of international assistance. One of the key steps is the full integration of the Ukrainian electricity and gas markets with European ones, planned for 2025. This will ensure supply stability and open up new investment opportunities [11]. As a result of military action, Ukraine`s energy system has suffered significant damage, making electricity imports from the EU an important support measure. Supplies of approximately 1.7 GW have already been organized, helping to cover the deficit in regions with damaged generating capacity. This allows for meeting the minimum needs of the population and maintaining economic activity [4]. Three nuclear power plants form the basis of a stable energy supply: Rivne, Khmelnytskyi, and South Ukraine. The Rivne NPP, located in the northwest of the country, is relatively safe due to its distance from active hostilities, but the threat of damage to the power grid remains. The Khmelnytskyi NPP supplies electricity to the central and western regions and is important for energy cooperation with the EU [12]. The South Ukraine NPP supplies electricity to the southern and central regions, but its operation is complicated by its proximity to the war zone. The Zaporizhzhia NPP, which previously produced approximately 25% of the country's electricity, is now under the control of Russian troops, significantly limiting its functionality. As a result, in order to ensure the sustainable development of Ukraine's energy system, it is necessary to combine the modernization of existing facilities, active integration with European markets, an increase in the share of renewable energy, and enhanced protection of critical infrastructure. Conclusion. Autonomous energy systems based on renewable energy sources (RES) have substantial potential to ensure stable and uninterrupted energy supply in Ukraine, especially during crises caused by military action and the destruction of centralized infrastructure. Their deployment significantly reduces dependence on centralized sources, which can be vulnerable to external attacks or technical failures. One of the key advantages of autonomous systems is their ability to operate in a decentralized mode, which provides greater flexibility and adaptability of the energy
