Public Service Co of NM

What This Utility Data Tells You

Public Service Co of NM is an investor-owned utility operating in New Mexico under EIA identifier 15473. It reports service to approximately 548,019 customer accounts and generated about $1.13 billion in annual electric revenue, with a service footprint spanning 108 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 Public Service Co of NM customer experienced 106.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 0.84 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 92.2 minutes, the gap between that figure and the headline 106.0 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Public Service Co of NM's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 128.0 to 106.0 minutes across that span, a direction regulators and prospective customers tend to watch closely.
