Marathon Power LLC
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 2023, final release. Monthly state figures run to July 2026.
In its Form EIA-861 filing for 2023, Marathon Power LLC, a retail power marketer, reported 2,097 residential customers in New York and 3 other states.
It sells energy only: another company delivers the power and bills for delivery, so the revenue it reports to EIA covers part of each customer's bill. Its energy-only revenue came to 10.87¢ per kilowatthour in 2023, which is not comparable with the bundled New York average of 22.24¢.
EIA's reliability file has no SAIDI or SAIFI entry for it in 2023; smaller respondents and energy-only suppliers are not asked for one.

Part-bill revenue per kWh covers energy without delivery, so it is shown beside the state's bundled average for scale only, not as a comparison. EIA describes its early release as not fully edited; it is shown for this utility alone and enters no average, median or rank on this site.
Sales by sector, 2023
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 2,097 | 55.8 GWh | 3% | $6,067,700 | — |
| Commercial | 15,276 | 2 TWh | 97% | $169,933,100 | — |
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: 297.8 GWh in total, of which 0% was its own net generation and 297.8 GWh was bought wholesale.
