A & N Electric Coop is a member-owned electric cooperative operating in Virginia under EIA identifier 84. It reports service to approximately 36,997 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 61 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 A & N Electric Coop customer experienced 5.5 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. SAIFI — the average number of outage events per customer — was 0.04 for the same period, so customers statistically faced roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 2.9 minutes — the gap between that figure and the headline 5.5 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for A & N Electric Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 329.5 to 5.5 minutes over that window — a meaningful direction for prospective customers and regulators watching capital investment outcomes. 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.

A & N Electric Coop serves 61 ZIP codes in Virginia.
A & N Electric Coop had a SAIDI of 5.5 minutes in 2023, meaning the average customer experienced about 6 minutes of outages that year. This is below the national average, indicating above-average reliability.
A & N Electric Coop is classified as a Cooperative serving Virginia. Electric cooperatives are member-owned nonprofit utilities, typically serving rural areas.
SAIDI (System Average Interruption Duration Index) measures the average total minutes per year that a customer of A & N Electric Coop experiences power outages. A lower SAIDI indicates better reliability. The national average is roughly 120-180 minutes per year, so comparing A & N Electric Coop's SAIDI to that benchmark shows whether this utility is above or below average.
A & N Electric Coop serves approximately 36,997 customers in Virginia. Customer count can affect reliability metrics because larger utilities may face different infrastructure challenges compared to smaller ones.
A & N Electric Coop has 4 years of reliability data (2020-2023). SAIDI has remained relatively stable over this period. Review the trend table above for year-by-year detail.
SAIDI "without major event days" (SAIDI nMED) excludes outages caused by hurricanes, ice storms, and other catastrophic weather events. It better reflects day-to-day infrastructure reliability rather than vulnerability to extreme weather. Both standard SAIDI and SAIDI nMED are shown in the reliability trend table above.
