What This Utility Data Tells You

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.

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 is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 22.8 minutes; the difference from the headline 37.0 shows how much of the outage total came from weather rather than everyday grid issues.
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.
