What mid-pack Karnes Electric Coop Inc filings show

Karnes Electric Coop Inc is a member-owned electric cooperative operating in Texas under EIA identifier 10009. It reports service to approximately 22,716 customer accounts and generated about $0.12 billion in annual electric revenue, with a service footprint spanning 40 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 Karnes Electric Coop Inc customer experienced 133.5 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 1.16 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 114.2 minutes, and the spread against the headline 133.5 indicates how much weather, versus routine infrastructure, drove the outage total.

Karnes Electric 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. Over that window, SAIDI moved from 163.4 down to 133.5 minutes, a trend worth noting for anyone weighing capital investment outcomes.
