City of Dickson

What This Utility Data Tells You

City of Dickson is a municipally-owned utility operating in Tennessee under EIA identifier 5148. It reports service to approximately 38,376 customer accounts and generated about $0.09 billion in annual electric revenue, with a service footprint spanning 21 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 Dickson customer experienced 1308.5 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that runs well past the 120–180 minute national benchmark, which can reflect storm-exposed terrain, an aging grid, or slower restoration times. The SAIFI figure, which tracks average outage events per customer, came in at 3.83 for the same period, meaning customers statistically saw about 4 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 368.7 minutes, the gap between that figure and the headline 1308.5 reveals how much weather, not day-to-day infrastructure, drove outages.

City of Dickson 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 951.3 to 1308.5 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
