What mid-pack Shenandoah Valley Elec Coop filings show
Shenandoah Valley Elec Coop is a member-owned electric cooperative operating in Virginia under EIA identifier 17066. It reports service to approximately 99,494 customer accounts and generated about $0.28 billion in annual electric revenue, with a service footprint spanning 91 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 Shenandoah Valley Elec Coop customer experienced 182.8 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 1.73, putting the typical customer at roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 182.8 minutes; the difference from the headline 182.8 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Shenandoah Valley Elec Coop's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 160.0 to 182.8 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
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.

Price vs. reliability
Where Shenandoah Valley Elec Coop sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Shenandoah Valley Elec Coop charges more per customer than 67% of them, and is more reliable (lower SAIDI) than 49% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
Revenue per customer: $2,832/year · Latest SAIDI: 182.8 minutes/year.
