What This Utility Data Tells You

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.
