What This Utility Data Tells You

Santee Electric Coop, Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 16606. It reports service to approximately 44,603 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 27 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 Santee Electric Coop, Inc customer experienced 232.6 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. Excluding major event days (hurricanes, ice storms), SAIDI drops to 146.2 minutes — the gap between that figure and the headline 232.6 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Santee 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 257.0 to 232.6 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.
