Methodology & data

Average residential electricity price in cents per kWh from the published state-level dataset. Values are used as a reference benchmark for comparison and estimation.

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.
