Provo City Corp is a municipally-owned utility operating in Utah under EIA identifier 15444. It reports service to approximately 40,894 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 10 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average Provo City Corp customer experienced 33.2 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 0.51 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 33.2 minutes; the difference from the headline 33.2 shows how much of the outage total came from weather rather than everyday grid issues.
Provo City Corp 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 21.6 to 33.2 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
