Long Island Power Authority
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.
Long Island Power Authority serves 1,029,955 residential customers in New York as a state-owned utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 3 counties.
Its average residential price that year was 24.57¢ per kilowatthour, about the same as the New York average of 24.43¢ and 49% above 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 $181.50 a month on average use of 739 kWh a month. Across New York the average bill was $139.53 on 571 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
The price covers the 1,029,943 residential customers on bundled service. A further 12 take delivery only and buy their energy from another supplier; EIA collects just part of their bill from this respondent, so they are left out of the average.
For reliability it reported a SAIDI of 63.5 minutes per customer with major event days included and 59.3 minutes with them excluded, calculated under another method. The median among New York utilities reporting was 63.5 minutes with major event days; this utility's figure is about the same as that median.
The average price is up 20.5% on 2019, against up 36.2% for New York as a whole, and up 10.0% on 2023. EIA's early release for 2025, which has not been fully edited, shows 26.17¢.

|---|---|---|---|---|---|
| Residential | 1,029,955 | 9.1 TWh | 50% | $2,243,216,600 | 24.57¢ |

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: 18.9 TWh in total, of which 9.8% was its own net generation and 17 TWh was bought wholesale; summer peak demand 4,985 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 0.75 interruptions per customer with major event days, 0.72 without; CAIDI 85.1 minutes per interruption. EIA's New York total across all reporting utilities was 219.9 minutes with major event days and 72.0 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.
