NE Edge data center at Millstone nuclear plant

Also called: NE Edge Waterford, NE Edge-Waterford LLC, Millstone data center

NE Edge wanted to build two very large data center buildings on the Millstone nuclear plant property and buy power directly from the plant. The state Siting Council would not approve the needed site change in 2024, and the town says the deal ended in March 2026.

✔ ConfirmedSourceLast checked: Oct 8, 2026

Where things stand: The town's fee deal with the developer ended in March 2026 after the developer defaulted. The state Siting Council never approved the site change it needed.

🕒 Latest update (March 17, 2026): Waterford's First Selectman announced the project had ended because NE Edge-Waterford LLC defaulted on the host fee agreement.
