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. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2020, the average Anchorage Municipal Light and Power customer experienced 68.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Over the same period, SAIFI (outage events per customer) was 0.27, putting the typical customer at roughly 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 18.1 minutes; the difference from the headline 68.7 shows how much of the outage total came from weather rather than everyday grid issues.
Only a single year of reliability data is available, so multi-year trend analysis is not yet possible for Anchorage Municipal Light and Power.
