What mid-pack City of Morristown - (TN) filings show

City of Morristown - (TN) is a municipally-owned utility operating in Tennessee under EIA identifier 12988. It reports service to approximately 16,321 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 4 ZIP codes. 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 Morristown - (TN) customer experienced 145.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 2.00 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 56.1 minutes, and the spread against the headline 145.2 indicates how much weather, versus routine infrastructure, drove the outage total.

City of Morristown - (TN) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI dropped from 184.5 to 145.2 minutes across that span, a direction regulators and prospective customers tend to watch closely.
