Tri-County Elec Member Corp (NC)

What This Utility Data Tells You

Tri-County Elec Member Corp (NC) is a member-owned electric cooperative operating in North Carolina under EIA identifier 18957. It reports service to approximately 26,624 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 26 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.

In 2023, the average Tri-County Elec Member Corp (NC) customer experienced 193.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 1.54 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 130.9 minutes; the difference from the headline 193.7 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), Tri-County Elec Member Corp (NC)'s reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 150.5 to 193.7 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
