Versant Power is a 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 metric called SAIDI (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. SAIFI — the average number of outage events per customer — was 3.91 for the same period, so customers statistically faced roughly 4 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 303.0 minutes — the gap between that figure and the headline 2475.0 reveals how much weather, not day-to-day infrastructure, drove outages.
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. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.

Versant Power serves 112 ZIP codes in Maine.
Versant Power had a SAIDI of 2475.0 minutes in 2023, meaning the average customer experienced about 2475 minutes of outages that year. This is above the national average, indicating below-average reliability.
Versant Power is classified as a IOU serving Maine. Investor-owned utilities (IOUs) are for-profit companies regulated by state public utility commissions.
SAIDI (System Average Interruption Duration Index) measures the average total minutes per year that a customer of Versant Power experiences power outages. A lower SAIDI indicates better reliability. The national average is roughly 120-180 minutes per year, so comparing Versant Power's SAIDI to that benchmark shows whether this utility is above or below average.
Versant Power serves approximately 117,729 customers in Maine. Customer count can affect reliability metrics because larger utilities may face different infrastructure challenges compared to smaller ones.
Versant Power has 4 years of reliability data (2020-2023). SAIDI has remained relatively stable over this period. Review the trend table above for year-by-year detail.
SAIDI "without major event days" (SAIDI nMED) excludes outages caused by hurricanes, ice storms, and other catastrophic weather events. It better reflects day-to-day infrastructure reliability rather than vulnerability to extreme weather. Both standard SAIDI and SAIDI nMED are shown in the reliability trend table above.
