What short-outage City of Fort Collins - (CO) filings show
City of Fort Collins - (CO) is a municipally-owned utility operating in Colorado under EIA identifier 6604. It reports service to approximately 79,036 customer accounts and generated about $0.16 billion in annual electric revenue, with a service footprint spanning 8 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average City of Fort Collins - (CO) customer experienced 19.9 minutes of power interruptions, a measure known as SAIDI, or 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. SAIFI, the average number of outage events per customer, was 0.24 for the same period, so customers statistically faced roughly 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 19.9 minutes; the difference from the headline 19.9 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of Fort Collins - (CO), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 10.2 to 19.9 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
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.
