The article is devoted to a comprehensive analysis of the innovative potential of small hydropower as a strategic instrument for ensuring Ukraine’s energy security in the context of wartime challenges and post-war recovery of the energy system. The technological advantages of small hydropower plants (SHPPs) compared to large hydropower plants and other energy sources are examined, including: decentralized generation, relatively short construction timelines, minimal environmental impact, the possibility of using existing hydrotechnical infrastructure, and stability of electricity production. The available hydroenergy potential of Ukraine’s rivers is analyzed, and prospective locations for SHPP deployment in various regions of the country are identified, taking into account hydrological, environmental, and economic factors. The study provides a detailed examination of the economic aspects of small hydropower development, including an analysis of the levelized cost of electricity (LCOE), capital and operational expenditures, investment payback periods, the potential contribution to the country’s energy balance, and the impact on the decarbonization of the economy. A comparative analysis of the environmental characteristics of SHPPs with traditional energy sources is presented, assessing their impact on aquatic ecosystems, possibilities for biodiversity preservation, and minimization of negative consequences associated with hydrotechnical construction. Particular attention is given to the analysis of international experience in small hydropower development in leading countries (China, Norway, Austria, Switzerland, Canada), state support mechanisms, and incentives for investment in renewable energy. The study investigates regulatory challenges related to the need to simplify licensing and permitting procedures for SHPP construction, and to adapt the “green” tariff and renewable energy support mechanisms to current realities. It is substantiated that the development of small hydropower may become a key factor in diversifying the energy balance, enhancing the resilience of the energy system to external threats, ensuring regional energy autonomy, and promoting the sustainable development of rural areas. The research results form a scientific and practical foundation for the development of a national strategy for small hydropower and for defining priority directions of investment in renewable energy in the context of post-war recovery and achieving Ukraine’s climate goals.
