East Central Oklahoma Elec Coop Inc is a member-owned electric cooperative operating in Oklahoma under EIA identifier 5598. It reports service to approximately 36,997 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 44 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 East Central Oklahoma Elec Coop Inc customer experienced 364.4 minutes of power interruptions, a measure known as SAIDI, or 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 2.06, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 157.1 minutes, the gap between that figure and the headline 364.4 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for East Central Oklahoma Elec Coop Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 324.1 to 364.4 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
