How the records were calculated
- Average bill divides residential revenue by reported customers. Usage per customer divides residential kWh by the same count. Revenue per kWh divides total revenue by total kWh. Annual monthly averages divide each annual per-customer total by 12. Individual bills depend on usage, tariff and charges.
- The contribution from revenue per kWh multiplies its change by the average of the two usage figures. The contribution from usage multiplies its change by the average of the two per-kWh figures. These contributions sum to the bill change before display rounding.
- Utility annual rows use observed EIA-861 full-service residential data. A comparison requires matching form part and balancing-authority coverage. Monthly utility rows are reported full-service data from EIA-861M. State and national monthly totals include EIA adjustments. Compare the same calendar month across years to account for seasonality.
- EIA-112 utility records match the EIA utility directory by unambiguous utility name and state. The report counts nonpayment events, including repeats on the same account. Reconnection totals cover events during the same month. State totals include EIA adjustments. An unavailable cell indicates missing or unmatched data.
- Service counties come from the 2025 EIA-861 directory. A listed utility can serve part of a county. Bill averages on a utility page cover its reported customers across the state.
