City of St George is a municipally-owned utility operating in Utah under EIA identifier 17874. It reports service to approximately 33,138 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 7 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 City of St George customer experienced 37.0 minutes of power interruptions — a metric called SAIDI (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. Excluding major event days (hurricanes, ice storms), SAIDI drops to 22.8 minutes — the gap between that figure and the headline 37.0 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of St George, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 24.5 to 37.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
