What long-outage Surry-Yadkin Elec Member Corp filings show
Surry-Yadkin Elec Member Corp is a member-owned electric cooperative operating in North Carolina under EIA identifier 18339. It reports service to approximately 28,006 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 42 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 Surry-Yadkin Elec Member Corp customer experienced 372.2 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 1.94, putting the typical customer at roughly 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 156.2 minutes, and the spread against the headline 372.2 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Surry-Yadkin Elec Member Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 422.6 down to 372.2 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.
