What This Utility Data Tells You

Easley Combined Utility System is a municipally-owned utility operating in South Carolina under EIA identifier 6709. It reports service to approximately 17,011 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 3 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.

In 2023, the average Easley Combined Utility System customer experienced 104.9 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI — the average number of outage events per customer — was 1.33 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 104.9 minutes — the gap between that figure and the headline 104.9 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Easley Combined Utility System, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 342.3 to 104.9 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.
