Sourced arguments and ready-to-send letters — every figure links to a primary record. Edit to add your own story.

Power & your bill

42 MW of new demand — roughly a city of 34,000 homes.

Large new loads can raise transmission and capacity costs that land on every ratepayer. Residential power in VA is 17.4¢/kWh, up 13.7% year-over-year. (MW→homes is a rough ~800/MW planning figure.)

Source

Water

~46,110 gallons/day — about 154 households' worth.

Evaporative cooling can consume drinking water in volumes that strain local supply, especially in drought. Ask whether closed-loop / non-potable cooling is required.

Source

Process

Demand a full, public review — not a rubber stamp.

Ask for an independent noise study, a water-and-power impact assessment, enforceable conditions (setbacks, hours, cooling type), and that the record stays open for written comment. Procedural shortcuts have voided approvals elsewhere.

Public comment (editable)

Dear members of the board,

I am a resident of Ashburn, Loudoun County, VA and I am writing about the proposed H5 Data Centers Ashburn (Prime Data Centers).

According to public records compiled by DataCentersExposed, it would add roughly 42 MW of electricity demand; it is associated with about 46,110 gallons/day of water use.

I am concerned about the impact on our electricity bills, our water, noise and air quality near homes and schools, and whether the public benefits justify any tax incentives. I respectfully ask that you impose enforceable operating conditions and independent monitoring on this facility, and that you keep the record open for public comment.

Specifically, I ask the board to require: an independent noise study at the property line; a water- and power-impact assessment; enforceable conditions on cooling type, operating hours, and setbacks; and clawback provisions if commitments aren't met.

Thank you for your service and for considering this comment.

Sincerely,
[Your name]
