Los Alamos County

What This Utility Data Tells You

Los Alamos County is a municipally-owned utility operating in New Mexico under EIA identifier 11204. It reports service to approximately 9,275 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 6 ZIP codes. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.

In 2023, the average Los Alamos County customer experienced 27.2 minutes of power interruptions, a measure known as SAIDI, or 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 0.26 for the same period, so customers statistically faced roughly 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 27.2 minutes; the difference from the headline 27.2 shows how much of the outage total came from weather rather than everyday grid issues.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Los Alamos County, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 69.0 to 27.2 minutes across that span, a direction regulators and prospective customers tend to watch closely.
