What long-outage Guernsey-Muskingum El Coop Inc filings show
Guernsey-Muskingum El Coop Inc is a member-owned electric cooperative operating in Ohio under EIA identifier 7891. It reports service to approximately 17,173 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 45 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.
In 2023, the average Guernsey-Muskingum El Coop Inc customer experienced 545.3 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. The SAIFI figure, which tracks average outage events per customer, came in at 2.86 for the same period, meaning customers statistically saw about 3 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 380.1 minutes; the difference from the headline 545.3 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Guernsey-Muskingum El Coop Inc's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 422.0 to 545.3 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.
