Upper Cumberland E M C

What This Utility Data Tells You

Upper Cumberland E M C is a member-owned electric cooperative operating in Tennessee under EIA identifier 19574. It reports service to approximately 53,364 customer accounts and generated about $0.12 billion in annual electric revenue, with a service footprint spanning 43 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 Upper Cumberland E M C customer experienced 344.0 minutes of power interruptions — a metric called SAIDI (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 255.3 minutes — the gap between that figure and the headline 344.0 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Upper Cumberland E M C, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 571.1 to 344.0 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.
