What mid-pack Northern Virginia Elec Coop filings show
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, the industry-standard SAIDI metric (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 0.88 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 40.3 minutes, and the spread against the headline 110.7 indicates how much weather, versus routine infrastructure, drove the outage total.
Northern Virginia Elec Coop 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 54.9 to 110.7 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
