What long-outage Alaska Power and Telephone Co filings show
Alaska Power and Telephone Co is an investor-owned utility operating in Alaska under EIA identifier 219. It reports service to approximately 8,368 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 22 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.
In 2023, the average Alaska Power and Telephone Co customer experienced 571.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That exceeds the 120–180 minute national benchmark by a wide margin, a pattern often tied to severe weather exposure, older infrastructure, or longer repair windows. The SAIFI figure, which tracks average outage events per customer, came in at 7.32 for the same period, meaning customers statistically saw about 7 distinct interruptions that year.
Alaska Power and Telephone Co has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 367.2 to 571.0 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.
