What long-outage Trinity Valley Elec Coop Inc filings show

Trinity Valley Elec Coop Inc is a member-owned electric cooperative operating in Texas under EIA identifier 18976. It reports service to approximately 85,223 customer accounts and generated about $0.17 billion in annual electric revenue, with a service footprint spanning 12 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 Trinity Valley Elec Coop Inc customer experienced 542.0 minutes of power interruptions, a metric called SAIDI (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. Over the same period, SAIFI (outage events per customer) was 3.22, putting the typical customer at roughly 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 189.0 minutes, and the spread against the headline 542.0 indicates how much weather, versus routine infrastructure, drove the outage total.

Trinity Valley Elec Coop Inc 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 170.0 to 542.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
