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

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)

Edit freely before sending — it's a starting point. Add your own story; personal comments carry the most weight.

What this site costs the grid

source: PJM RPM auction reports

Dominion (Virginia / NC) · 2027/28 auction

$333 /MW-day

Peaked at $444/MW-day in 2025/26 — 1.65× the rest of PJM

PJM's capacity auction sets a $/MW-day price that utilities pass on to every household and business in the zone. This site sits in PJM's DOM pricing zone, where soaring data-center demand is a documented driver. See the full zone-by-zone breakdown →

This site's capacity-market cost (estimated)

$9.1M to $19.4M/yr

An estimated ~75 to 160 MW of load at the zone's $333/MW-day, annualized — the capacity charge a load this size carries at the current auction price. Estimated from the building footprint at 200 to 400 W/ft² (the typical range for modern data centers). A rough order-of-magnitude figure, not a metered or permitted capacity.

Separately, a typical home in this zone pays an estimated $4 to $10/mo more on the capacity portion of its bill that PJM's market monitor attributes to data-center demand. See your address's full impact →
