What This Utility Data Tells You
PacifiCorp is an investor-owned utility operating in California under EIA identifier 14354. It reports service to approximately 1,030,992 customer accounts and generated about $2.29 billion in annual electric revenue, with a service footprint spanning 500 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average PacifiCorp customer experienced 2381.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 3.87 for the same period, so customers statistically faced roughly 4 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 177.2 minutes, the gap between that figure and the headline 2381.1 reveals how much weather, not day-to-day infrastructure, drove outages.
PacifiCorp 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 span, SAIDI rose from 381.4 to 2381.1 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
