City of Wilson - (NC) is a municipally-owned utility operating in North Carolina under EIA identifier 20785. It reports service to approximately 36,199 customer accounts and generated about $0.12 billion in annual electric revenue, with a service footprint spanning 4 ZIP codes.

In 2023, the average City of Wilson - (NC) customer experienced 52.6 minutes of power interruptions, the industry-standard SAIDI metric (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. SAIFI, the average number of outage events per customer, was 0.69 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 52.6 minutes, and the spread against the headline 52.6 indicates how much weather, versus routine infrastructure, drove the outage total.
City of Wilson - (NC) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI dropped from 73.9 to 52.6 minutes across that span, a direction regulators and prospective customers tend to watch closely.
