Cumberland Elec Member Corp

What This Utility Data Tells You

Cumberland Elec Member Corp is a member-owned electric cooperative operating in Tennessee under EIA identifier 4624. It reports service to approximately 109,845 customer accounts and generated about $0.31 billion in annual electric revenue, with a service footprint spanning 44 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 Cumberland Elec Member Corp customer experienced 871.5 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 3.85, putting the typical customer at roughly 4 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 161.2 minutes, and the spread against the headline 871.5 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Cumberland Elec Member Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 213.2 to 871.5 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
