What long-outage Cumberland Elec Member Corp filings show
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.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Cumberland Elec Member Corp sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Cumberland Elec Member Corp charges more per customer than 66% of them, and is more reliable (lower SAIDI) than 9% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
