Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

   Underlying source

Source notes

Connecticut has no hyperscale data centers. Governor Lamont's administration has since required new data centers to bring their own power generation rather than draw from the grid, and has proposed a PILOT framework in lieu of the prior tax incentive structure. Only one company (Cigna) used Connecticut's data center tax incentive since its enactment.

Proposed direct electrical interconnection to Millstone Units 2 and 3; 15% of Millstone output reserved for data centers. Host fee agreement executed March 2023 ($231M over 30 years to Waterford in lieu of taxes).
