City of Columbus - (MS) is a municipally-owned utility operating in Mississippi under EIA identifier 4068. It reports service to approximately 12,664 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 5 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 Columbus - (MS) customer experienced 86.2 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. Over the same period, SAIFI (outage events per customer) was 0.91, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 67.5 minutes; the difference from the headline 86.2 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 Columbus - (MS)'s reliability record can be judged on trend rather than one isolated year. Over that window, SAIDI moved from 152.6 down to 86.2 minutes, a trend worth noting for anyone weighing capital investment outcomes.
