Los Alamos County
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Annual figures: Form EIA-861 for 2024, final release. Monthly state figures run to July 2026.
Los Alamos County serves 7,742 residential customers in New Mexico as a municipal utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 1 county.
Its average residential price that year was 14.15¢ per kilowatthour, about the same as the New Mexico average of 14.20¢ and 14% below the US average of 16.48¢. The figure is residential revenue divided by residential sales, so it folds in fixed charges, riders and every rate schedule the utility bills under.
That works out to an average residential bill of $93.51 a month on average use of 661 kWh a month. Across New Mexico the average bill was $92.88 on 654 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
For reliability it reported a SAIDI of 30.4 minutes per customer with major event days included and 30.4 minutes with them excluded, calculated under IEEE 1366 standard. The median among New Mexico utilities reporting was 190.0 minutes with major event days; this utility's figure is 84% below that median.
The average price is up 7.5% on 2019, against up 13.5% for New Mexico as a whole, and up 15.3% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.79¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 7,742 | 61.4 GWh | 13% | $8,687,900 | 14.15¢ |
| Commercial | 838 | 56.3 GWh | 12% | $7,570,800 | 13.45¢ |
| Industrial | 1 | 368.1 GWh | 76% | $31,036,800 | 8.43¢ |
Customers, sales and revenue count every service type the utility reported (bundled, energy-only and delivery-only). The price column uses bundled service alone, because part-bill revenue would understate it. Sources of energy: 499.5 GWh in total, of which 4.9% was its own net generation and 72.4 GWh was bought wholesale; summer peak demand 72 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 0.29 interruptions per customer with major event days, 0.29 without; CAIDI 106.4 minutes per interruption. EIA's New Mexico total across all reporting utilities was 278.8 minutes with major event days and 156.5 without. Major event days are storms and similar events that a utility's chosen method sets apart; methods differ, so treat comparisons as approximate. What SAIDI and SAIFI mean.

Generation at plants it operates, 2025
- Hydro 100% 20.1 GWh
Net generation of 20.1 GWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (72.4 GWh in 2024), sell generation to others and may co-own plants that another company operates.
Counties in its service territory
Counties the utility listed on Form EIA-861 for 2024. Listing a county does not mean the utility serves all of it.
