What short-outage San Isabel Electric Assn, Inc filings show
San Isabel Electric Assn, Inc is a member-owned electric cooperative operating in Colorado under EIA identifier 16616. It reports service to approximately 25,872 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 32 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.
In 2023, the average San Isabel Electric Assn, Inc customer experienced 85.7 minutes of power interruptions, a measure known as SAIDI, or 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 0.77, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 85.7 minutes, the gap between that figure and the headline 85.7 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for San Isabel Electric Assn, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 316.8 down to 85.7 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.
