Versant Power
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.
In its Form EIA-861 filing for 2024, Versant Power, an investor-owned utility, reported 137,906 residential customers in Maine, with a service territory that touches 6 counties.
Its average residential price that year was 28.08¢ per kilowatthour, 16% above the Maine average of 24.29¢ and 70% 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 $141.76 a month on average use of 505 kWh a month. Across Maine the average bill was $133.60 on 550 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
The price covers the 130,632 residential customers on bundled service. A further 7,274 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 1,206.0 minutes per customer with major event days included and 478.0 minutes with them excluded, calculated under IEEE 1366 standard. The median among Maine utilities reporting was 1,206.0 minutes with major event days; this utility's figure is about the same as that median.
The average price is up 45.6% on 2019, against up 35.8% for Maine as a whole, and down 3.5% on 2023. EIA's early release for 2025, which has not been fully edited, shows 30.15¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 137,906 | 832.1 GWh | 43% | $228,840,200 | 28.08¢ |

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: 2 TWh in total, of which 0% was its own net generation and 2 TWh was bought wholesale; summer peak demand 369 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 4.38 interruptions per customer with major event days, 3.10 without; CAIDI 275.4 minutes per interruption. EIA's Maine total across all reporting utilities was 1,748.6 minutes with major event days and 274.0 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.
