Cookson Hills Elec Coop, Inc is a member-owned electric cooperative operating in Oklahoma under EIA identifier 4296. It reports service to approximately 18,844 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 30 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 Cookson Hills Elec Coop, Inc customer experienced 183.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI, the average number of outage events per customer, was 0.93 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 107.7 minutes; the difference from the headline 183.3 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 Cookson Hills Elec Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 653.1 to 183.3 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
