What short-outage City of Lewisburg - (TN) filings show

City of Lewisburg - (TN) is a municipally-owned utility operating in Tennessee under EIA identifier 10960. It reports service to approximately 6,503 customer accounts and generated about $0.03 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 Lewisburg - (TN) customer experienced 28.6 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 0.96 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 10.3 minutes, and the spread against the headline 28.6 indicates how much weather, versus routine infrastructure, drove the outage total.

City of Lewisburg - (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 has improved from 49.1 to 28.6 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
