What mid-pack Lake Region Electric Coop, Inc - (OK) filings show
Lake Region Electric Coop, Inc - (OK) is a member-owned electric cooperative operating in Oklahoma under EIA identifier 10599. It reports service to approximately 26,196 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 34 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 Lake Region Electric Coop, Inc - (OK) customer experienced 248.2 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. Over the same period, SAIFI (outage events per customer) was 1.36, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 93.1 minutes; the difference from the headline 248.2 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 Lake Region Electric Coop, Inc - (OK), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 273.5 to 248.2 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
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.
