What long-outage Grayson-Collin Elec Coop, Inc filings show
Grayson-Collin Elec Coop, Inc is a member-owned electric cooperative operating in Texas under EIA identifier 7559. It reports service to approximately 84,009 customer accounts and generated about $0.19 billion in annual electric revenue, with a service footprint spanning 69 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-Collin Elec Coop, Inc customer experienced 465.5 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 182.8 minutes; the difference from the headline 465.5 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Grayson-Collin Elec Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 415.3 to 465.5 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.
