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.
