City of Ripley - (TN) is a municipally-owned utility operating in Tennessee under EIA identifier 27222. It reports service to approximately 6,620 customer accounts and generated about $0.02 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2023, the average City of Ripley - (TN) customer experienced 258.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 2.14 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 197.4 minutes; the difference from the headline 258.3 shows how much of the outage total came from weather rather than everyday grid issues.
City of Ripley - (TN) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 63.4 to 258.3 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
