Piedmont Electric Member Corp is a member-owned electric cooperative operating in North Carolina under EIA identifier 15023. It reports service to approximately 34,076 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 34 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 Piedmont Electric Member Corp customer experienced 212.1 minutes of power interruptions, the industry-standard SAIDI metric (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 1.86 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 167.8 minutes; the difference from the headline 212.1 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 Piedmont Electric Member Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 206.8 to 212.1 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
