Demand growth in Northern Virginia's power-hungry Data Center Alley is accelerating, and policymakers are trying to ensure new demand can be met reliably.

PJM stakeholders approved new generator deliverability tests and learned of a 3rd competitive window to address "unprecedented" data center load in Virginia.

The price tag on Dominion Energy’s “Data Center Alley” transmission upgrades in Northern Virginia has grown by $24.6 million to $627.6 million.

PJM transmission owners led by Dominion presented the Transmission Expansion Advisory Committee with more than $400 million in supplemental projects.

Dominion Energy plans $603 million in additional transmission spending to serve the unprecedented growth of data centers near Dulles Airport in Virginia.

The Virginia Corporation Commission approved Dominion Energy’s OSW project, but the utility’s CEO said the capacity performance guarantee is “disappointing.”

PJM said “Data Center Alley” in Northern Virginia needs more transmission to support a 4-GW increase in load, despite $230 million in pending projects.
