What This Utility Data Tells You

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. 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 York Electric Coop Inc customer experienced 96.2 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. SAIFI — the average number of outage events per customer — was 0.82 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 89.0 minutes — the gap between that figure and the headline 96.2 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for York Electric Coop Inc, which lets you see whether reliability is trending up or down rather than judging from a single 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. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
