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.

In 2023, the average Edisto Electric Coop, Inc customer experienced 453.3 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index).

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.
