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)
$2.4M to $5.5M/yr

An estimated ~20 to 45 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 →
