Source data related to Sotnyk et al. (2026) "REGIONAL PLANNING OF POST-WAR ELECTRICITY INFRASTRUCTURE IN UKRAINE"

This is the accompanying dataset for the publication Sotnyk et al. (2026) “REGIONAL PLANNING OF POST-WAR ELECTRICITY INFRASTRUCTURE IN UKRAINE.” Please cite the article together with the Zenodo link when you use the data. This dataset provides regional output data from four modeled scenarios assessing the post-war electricity infrastructure in Ukraine in 2035. It includes detailed results on generation, storage, transmission, and their social, environmental and economic impacts across Ukraine’s 24 regions and five neighboring countries. Beyond the baseline scenarios, the dataset contains a sensitivity analysis exploring how ±20% variations in investment, operational, and fuel costs for renewable energy sources (RES) impact the spatial distribution of installed capacities (generation, storage, and transmission) across Ukrainian regions and nodes, as well as the electricity volumes produced by 9 selected technologies and the annual average marginal electricity prices within four scenarios. The data support scenario-based planning for a resilient, low-carbon reconstruction of the electricity sector.
