City of Logan - (UT) is a municipally-owned utility operating in Utah under EIA identifier 11135. It reports service to approximately 21,541 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 7 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average City of Logan - (UT) customer experienced 35.5 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. The SAIFI figure, which tracks average outage events per customer, came in at 0.49 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 35.5 minutes, and the spread against the headline 35.5 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of Logan - (UT), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 26.4 to 35.5 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
