Mountain Electric Coop, Inc is a member-owned electric cooperative operating in North Carolina under EIA identifier 13027. It reports service to approximately 20,002 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 35 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 Mountain Electric Coop, Inc customer experienced 186.6 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI, the average number of outage events per customer, was 1.95 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 186.6 minutes; the difference from the headline 186.6 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Mountain Electric Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 198.0 down to 186.6 minutes, a trend worth noting for anyone weighing capital investment outcomes.
