Valley Electric Assn, Inc is a member-owned electric cooperative operating in Nevada under EIA identifier 19840. It reports service to approximately 24,659 customer accounts and generated about $0.09 billion in annual electric revenue, with a service footprint spanning 26 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 Valley Electric Assn, Inc customer experienced 144.6 minutes of power interruptions, a metric called SAIDI (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 1.51 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 41.4 minutes, the gap between that figure and the headline 144.6 reveals how much weather, not day-to-day infrastructure, drove outages.
Valley Electric Assn, Inc has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 68.5 to 144.6 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
