What mid-pack Chugach Electric Assn Inc filings show

It reports service to approximately 113,253 customer accounts and generated about $0.33 billion in annual electric revenue, with a service footprint spanning 30 ZIP codes.

In 2023, the average Chugach Electric Assn Inc customer experienced 189.1 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 1.50, putting the typical customer at roughly 2 distinct interruptions that year.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Chugach Electric Assn Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 113.0 to 189.1 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.
