What mid-pack EnergyUnited Elec Member Corp filings show

EnergyUnited Elec Member Corp is a member-owned electric cooperative operating in North Carolina under EIA identifier 21632. It reports service to approximately 139,079 customer accounts and generated about $0.28 billion in annual electric revenue, with a service footprint spanning 101 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 EnergyUnited Elec Member Corp customer experienced 221.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 1.64 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 129.4 minutes, and the spread against the headline 221.0 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for EnergyUnited Elec Member Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 597.2 down to 221.0 minutes, a trend worth noting for anyone weighing capital investment outcomes.
