What mid-pack Duke Energy Ohio Inc filings show
Duke Energy Ohio Inc is an investor-owned utility operating in Ohio under EIA identifier 3542. It reports service to approximately 360,034 customer accounts and generated about $0.79 billion in annual electric revenue, with a service footprint spanning 140 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average Duke Energy Ohio Inc customer experienced 168.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 0.99 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 103.6 minutes, and the spread against the headline 168.2 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), Duke Energy Ohio Inc's reliability record can be judged on trend rather than one isolated year. Over that window, SAIDI moved from 211.9 down to 168.2 minutes, a trend worth noting for anyone weighing capital investment outcomes.
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.
