Wake Electric Membership Corp is a member-owned electric cooperative operating in North Carolina under EIA identifier 19981. It reports service to approximately 53,873 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 26 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 Wake Electric Membership Corp customer experienced 277.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. SAIFI, the average number of outage events per customer, was 2.37 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 98.4 minutes; the difference from the headline 277.7 shows how much of the outage total came from weather rather than everyday grid issues.
Wake Electric Membership Corp has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 157.9 to 277.7 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
