Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: May 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility. For what's inside the all-in rate, see hidden electricity fees; for how rates and estimates are defined, see the methodology hub.
