Rappahannock Electric Coop is a member-owned electric cooperative operating in Virginia under EIA identifier 40228. It reports service to approximately 176,342 customer accounts and generated about $0.50 billion in annual electric revenue, with a service footprint spanning 157 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 Rappahannock Electric Coop customer experienced 205.4 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 1.78, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 173.2 minutes, the gap between that figure and the headline 205.4 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Rappahannock Electric Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 350.1 to 205.4 minutes across that span, a direction regulators and prospective customers tend to watch closely.
