Mean outage duration per year (2023)
Ohio Power Co is an investor-owned utility operating in Ohio under EIA identifier 14006. It reports service to approximately 791,647 customer accounts and generated about $1.98 billion in annual electric revenue, with a service footprint spanning 446 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 Ohio Power Co customer experienced 326.1 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 1.24 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 147.6 minutes, the gap between that figure and the headline 326.1 reveals how much weather, not day-to-day infrastructure, drove outages.
Ohio Power Co has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 254.6 to 326.1 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
