What short-outage City of Hamilton - (OH) filings show
City of Hamilton - (OH) is a municipally-owned utility operating in Ohio under EIA identifier 7977. It reports service to approximately 29,735 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 5 ZIP codes. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2023, the average City of Hamilton - (OH) customer experienced 76.6 minutes of power interruptions, the industry-standard SAIDI metric (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. SAIFI, the average number of outage events per customer, was 1.18 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 62.6 minutes, the gap between that figure and the headline 76.6 reveals how much weather, not day-to-day infrastructure, drove outages.
City of Hamilton - (OH) 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 32.1 to 76.6 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
