What long-outage Grayson Rural Electric Coop Corp filings show
Grayson Rural Electric Coop Corp is a member-owned electric cooperative operating in Kentucky under EIA identifier 7558. It reports service to approximately 15,576 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 25 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.
In 2023, the average Grayson Rural Electric Coop Corp customer experienced 531.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 2.93, putting the typical customer at roughly 3 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 293.3 minutes; the difference from the headline 531.0 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Grayson Rural Electric Coop Corp's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 338.4 to 531.0 minutes over that window, a shift that can point to 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.
