Analysis of the investment potential of the energy sector of Ukraine in the conditions of post-war reconstruction

The research emphasizes that Ukraine's energy sector has become a decisive factor for national resilience and long-term economic stability in the post-war recovery period. The destruction of critical infrastructure has turned the restoration of energy capacities into both an economic and security priority, requiring the attraction of large-scale domestic and foreign investments. The study highlights that the transition from a centralized, fossil-fuel-based model to a decentralized, innovative, and low-carbon system is not only a technological challenge but also a strategic opportunity to rebuild the country on new sustainable principles. Special attention is paid to the integration of European energy standards, improvement of regulatory mechanisms, and expansion of public-private partnerships as tools to mobilize capital and accelerate modernization. The study is devoted to a comprehensive analysis of the investment potential of the energy sector of Ukraine in the conditions of post-war recovery caused by unprecedented military aggression. As a result of targeted attacks, more than 40 GW of generating capacity was lost, which requires a fundamental transformation of the system. Particular attention is paid to identifying key investment priorities: increasing energy efficiency, large-scale development of renewable energy sources (RES), modernization of networks and creation of energy storage systems. The work first carried out a systematic analysis of multi-faceted risks (political, economic, technical and social) that accompany the implementation of these ambitious projects. Based on the analysis, a model of transition to a decentralized, low-carbon energy system with a potential of up to 40% “green” generation by 2030 is substantiated. Practical recommendations have been formulated to strengthen investment security by expanding international guarantees (ECA, MIGA, DFC) and completing regulatory modernization to attract private capital.
