What This Utility Data Tells You

Edisto Electric Coop, Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 5644. It reports service to approximately 21,121 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 37 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 Edisto Electric Coop, Inc customer experienced 453.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. Excluding major event days (hurricanes, ice storms), SAIDI drops to 336.6 minutes, the gap between that figure and the headline 453.3 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Edisto Electric Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 646.7 to 453.3 minutes across that span, a direction regulators and prospective customers tend to watch closely.
