About these numbers
Average bill = residential electricity revenue ÷ residential customers ÷ 12, from the US Energy Information Administration (2025, forms EIA-861, 861S and 861U). The 2026 price is from EIA's Electric Power Monthly, Table 5.6.B. The average bill is an average across all homes in the state, so individual bills vary widely around it. Full methodology.
