What short-outage City of Columbia - (MO) filings show
City of Columbia - (MO) is a municipally-owned utility operating in Missouri under EIA identifier 4045. It reports service to approximately 52,016 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 6 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 Columbia - (MO) customer experienced 48.4 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 0.61 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 39.2 minutes, and the spread against the headline 48.4 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of Columbia - (MO), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 77.9 down to 48.4 minutes, a trend worth noting for anyone weighing capital investment outcomes.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
