What long-outage Bolivar Energy Authority filings show
Bolivar Energy Authority is a municipally-owned utility operating in Tennessee under EIA identifier 1936. It reports service to approximately 11,361 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 17 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average Bolivar Energy Authority customer experienced 690.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 3.29, putting the typical customer at roughly 3 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 111.7 minutes; the difference from the headline 690.0 shows how much of the outage total came from weather rather than everyday grid issues.
Bolivar Energy Authority has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 78.3 to 690.0 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 Bolivar Energy Authority sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Bolivar Energy Authority charges more per customer than 47% of them, and is more reliable (lower SAIDI) than 14% 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.
