What This Utility Data Tells You
City of Clarksville - (TN) is a municipally-owned utility operating in Tennessee under EIA identifier 3704. It reports service to approximately 83,495 customer accounts and generated about $0.19 billion in annual electric revenue, with a service footprint spanning 4 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average City of Clarksville - (TN) customer experienced 1247.7 minutes of power interruptions, the industry-standard SAIDI metric (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. Over the same period, SAIFI (outage events per customer) was 2.83, putting the typical customer at roughly 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 106.9 minutes, and the spread against the headline 1247.7 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of Clarksville - (TN), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 189.7 to 1247.7 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
