What mid-pack Santee Electric Coop, Inc filings show
Santee Electric Coop, Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 16606. It reports service to approximately 44,603 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 27 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 Santee Electric Coop, Inc customer experienced 232.6 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. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 146.2 minutes; the difference from the headline 232.6 shows how much of the outage total came from weather rather than everyday grid issues.
Santee 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 257.0 down to 232.6 minutes, a trend worth noting for anyone weighing 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.
