How the community has taken it
Reception is a sourced signal, not an editorial judgment: opposed means documented, organized local opposition is the dominant signal on record.
Concerned Citizens of Waterford and East Lyme (CCWEL) formed in opposition. CT Siting Council denied Dominion's petition (January 2024) citing lack of information. Opposition demonstrated via ISO-NE data that both Millstone reactors were simultaneously inoperable for 5 weeks, contradicting developer's reliability claims. CT Attorney General reviewed monopolization concerns.
Power and water
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).
Notes on the record
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.
What the record does not establish, and the document that would
In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.
- Cooling method and water use
- Tax abatements or other public subsidy
- Permanent jobs promised
- Land area
Which document closes each gap
- Cooling method and water use
- The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
- Land area
- The rezoning application, the plat, or the deed recorded with the county.
