In 2023, the average Public Service Co of Colorado customer experienced 112.8 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 1.02, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 104.2 minutes; the difference from the headline 112.8 shows how much of the outage total came from weather rather than everyday grid issues.

Public Service Co of Colorado has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that window, SAIDI moved from 138.6 down to 112.8 minutes, a trend worth noting for anyone weighing capital investment outcomes.
