Component level cable and transformer cost dataset for synthetic electric distribution system analysis

This dataset contains cleaned component level cost and technical specification data for power distribution cables and transformers. It includes separate CSV files for cables and transformers, with variables describing component characteristics and cost values. Missing cable and transformer costs are completed using interpolation methods developed in this study, including regression based estimation and reference table based imputation. The dataset is intended to support benchmarking, cost estimation, and planning analysis in synthetic electric distribution system studies.
