What This Utility Data Tells You
Alaska Power and Telephone Co is a 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. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average Alaska Power and Telephone Co customer experienced 571.0 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. SAIFI — the average number of outage events per customer — was 7.32 for the same period, so customers statistically faced roughly 7 distinct interruptions that year.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Alaska Power and Telephone Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 367.2 to 571.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
