What short-outage South River Elec Member Corp filings show
South River Elec Member Corp is a member-owned electric cooperative operating in North Carolina under EIA identifier 17572. It reports service to approximately 47,704 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 35 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 South River Elec Member Corp customer experienced 52.9 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 52.9 minutes; the difference from the headline 52.9 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), South River Elec Member Corp's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 54.5 to 52.9 minutes across that span, a direction regulators and prospective customers tend to watch closely.
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.
