Kingsport Power Co

What This Utility Data Tells You

Kingsport Power Co is an investor-owned utility operating in Tennessee under EIA identifier 10331. It reports service to approximately 49,140 customer accounts and generated about $0.23 billion in annual electric revenue, with a service footprint spanning 4 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.

In 2023, the average Kingsport Power Co customer experienced 495.4 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, 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 2.07 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 191.5 minutes, and the spread against the headline 495.4 indicates how much weather, versus routine infrastructure, drove the outage total.

Kingsport Power Co 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 382.8 to 495.4 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
