What long-outage Versant Power filings show
Versant Power is an investor-owned utility operating in Maine under EIA identifier 1179. It reports service to approximately 117,729 customer accounts and generated about $0.27 billion in annual electric revenue, with a service footprint spanning 112 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average Versant Power customer experienced 2475.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that runs well past the 120–180 minute national benchmark, which can reflect storm-exposed terrain, an aging grid, or slower restoration times. The SAIFI figure, which tracks average outage events per customer, came in at 3.91 for the same period, meaning customers statistically saw about 4 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 303.0 minutes; the difference from the headline 2475.0 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Versant Power, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 1602.0 to 2475.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Versant Power sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Versant Power charges more per customer than 35% of them, and is more reliable (lower SAIDI) than 1% of them, placing it in the quadrant where it pays less and is less reliable. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
