City of Rocky Mount - (NC) is a municipally-owned utility operating in North Carolina under EIA identifier 16226. It reports service to approximately 29,196 customer accounts and generated about $0.07 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 Rocky Mount - (NC) customer experienced 115.5 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. The SAIFI figure, which tracks average outage events per customer, came in at 1.59 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 72.4 minutes, and the spread against the headline 115.5 indicates how much weather, versus routine infrastructure, drove the outage total.
City of Rocky Mount - (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 climbed from 101.4 to 115.5 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
