This paper proposes a methodology to generate sets of distribution feeders representative of any U.S. county for economic and policy studies. The methodology modifies prototypical feeders and organizes them into sets that (i) reproduce historical economic and infrastructure investment patterns and (ii) accommodate county-specific demand characteristics, including energy, peak, and building types. The approach relies on publicly available data, enabling systematic application across all U.S. counties and adaptation to other regions. The use of the resulting feeders is demonstrated through an electrification impact study in Alameda County, California.
