What mid-pack York Electric Coop Inc filings show
York Electric Coop Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 21002. It reports service to approximately 69,134 customer accounts and generated about $0.14 billion in annual electric revenue, with a service footprint spanning 30 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 York Electric Coop Inc customer experienced 96.2 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 0.82 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 89.0 minutes; the difference from the headline 96.2 shows how much of the outage total came from weather rather than everyday grid issues.
York 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. SAIDI has improved from 202.6 to 96.2 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.
