Anchorage Municipal Light and Power

What This Utility Data Tells You

Anchorage Municipal Light and Power is a municipally-owned utility operating in Alaska under EIA identifier 599. Customer count is not reported in the current EIA filing. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.

In 2020, the average Anchorage Municipal Light and Power customer experienced 68.7 minutes of power interruptions — a metric called SAIDI (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 0.27 for the same period, so customers statistically faced roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 18.1 minutes — the gap between that figure and the headline 68.7 reveals how much weather, not day-to-day infrastructure, drove outages.

Only a single year of reliability data is available, so multi-year trend analysis is not yet possible for Anchorage Municipal Light and Power. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
