What long-outage Cleveland Electric Illum Co filings show
Cleveland Electric Illum Co is an investor-owned utility operating in Ohio under EIA identifier 3755. It reports service to approximately 323,511 customer accounts and generated about $0.55 billion in annual electric revenue, with a service footprint spanning 100 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average Cleveland Electric Illum Co customer experienced 558.9 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. 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. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 117.7 minutes; the difference from the headline 558.9 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Cleveland Electric Illum Co's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 543.1 to 558.9 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
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.
