What long-outage Southeastern Electric Coop Inc - (OK) filings show

Southeastern Electric Coop Inc - (OK) is a member-owned electric cooperative operating in Oklahoma under EIA identifier 17603. It reports service to approximately 16,981 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 22 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 Southeastern Electric Coop Inc - (OK) customer experienced 387.8 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That runs well past the 120–180 minute national benchmark, which can reflect storm-exposed terrain, an aging grid, or slower restoration times. The SAIFI figure, which tracks average outage events per customer, came in at 6.12 for the same period, meaning customers statistically saw about 6 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 328.6 minutes; the difference from the headline 387.8 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), Southeastern Electric Coop Inc - (OK)'s reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 271.4 to 387.8 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
