Northern Virginia Elec Coop

What This Utility Data Tells You

Northern Virginia Elec Coop is a member-owned electric cooperative operating in Virginia under EIA identifier 13640. It reports service to approximately 180,323 customer accounts and generated about $0.86 billion in annual electric revenue, with a service footprint spanning 55 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.

In 2023, the average Northern Virginia Elec Coop customer experienced 110.7 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. SAIFI — the average number of outage events per customer — was 0.88 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 40.3 minutes — the gap between that figure and the headline 110.7 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Northern Virginia Elec Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 54.9 to 110.7 minutes, which may reflect either worsening weather exposure or delayed grid modernization. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
