Small utility: EIA collects only totals, so the price is the average across all customer types.

Illinois has retail electricity choice. Many households can buy electricity supply from a competing supplier, while the local utility still delivers it. The averages here combine utility and supplier sales as reported to the EIA; your state’s public utility commission lists licensed suppliers.
