Candidate utilities and average rates by ZIP code (NREL / OpenEI)

Candidate electric utilities serving a US ZIP code, with their average residential, commercial and industrial rates (NREL / Open Energy Data Initiative U.S. Electric Utility Companies and Rates look-up by ZIP code). One ZIP commonly maps to more than one utility, so the response is always a list. Reference/annual data, not a live billing rate - verify against the utility's published tariff before relying on it operationally.
