Tullahoma Board-Public Utils

What This Utility Data Tells You

Tullahoma Board-Public Utils is a municipally-owned utility operating in Tennessee under EIA identifier 19266. It reports service to approximately 11,180 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 Tullahoma Board-Public Utils customer experienced 68.8 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. Over the same period, SAIFI (outage events per customer) was 2.76, putting the typical customer at roughly 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 26.5 minutes, and the spread against the headline 68.8 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Tullahoma Board-Public Utils, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 73.8 down to 68.8 minutes, a trend worth noting for anyone weighing capital investment outcomes.
