City of Dyersburg

What This Utility Data Tells You

City of Dyersburg is a municipally-owned utility operating in Tennessee under EIA identifier 5509. It reports service to approximately 12,084 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. 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 Dyersburg customer experienced 57.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. 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 0.75, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 31.1 minutes; the difference from the headline 57.1 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), City of Dyersburg's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 68.6 to 57.1 minutes across that span, a direction regulators and prospective customers tend to watch closely.
