GIS-based analysis for identifying priority regions and developing renewable energy in post-war Ukraine

The ongoing geopolitical conflict between Ukraine and Russia has damaged more than half of Ukraine's energy infrastructure, which consequently has negatively influenced energy availability, affecting millions and forcing rapid changes in the consumption profile and security approaches. In this context, the value of renewable energy sources has increased, shifting from a pro-environmental concern to a security and economic necessity. This study provides a spatially explicit assessment of Ukraine's renewable energy potential, identifying priority regions for solar and wind power deployment as part of sustainable post-war reconstruction. Our methodology is based on the International Renewable Energy Agency's spatial analysis approach, incorporating geospatial data, and exclusion and opportunity criteria to evaluate the technical potential for generating renewable energy across different regions of Ukraine. Additionally, we applied a renewable energy need indicator to prioritize regions based on social, government, ecological, economic, and technological factors. The results show that the total potential for solar generation is 41.19 GW and for wind generation, 187.98 GW. Even if only a fraction of this potential is implemented, theoretically it could cover the electricity consumption needs that Ukraine had before the war. The research findings provide critical insights for policymakers, investors, and local authorities, offering a roadmap for integrating renewable energy into Ukraine's recovery strategy. The suitability maps and prioritization framework developed in this study serve as practical tools for guiding investment allocation, infrastructure planning, and stakeholder engagement to accelerate Ukraine's transition toward a more resilient and decentralized energy system.
