Notes on the record

Concept-stage: Holtec has a NYISO load-study request and a corporate HI-CLOUD announcement but, per its site VP (Dec 2024), 'no offer' and no tenant. Holtec cites up to 2,000 MW of existing grid interconnection, Hudson River access for cooling, dark fiber, and potential future SMR-300 on-site generation. The site sits within Holtec's 240-acre Indian Point decommissioning property; the Village of Buchanan/Town of Cortlandt zoning question is unresolved.

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.

Tax abatements or other public subsidy
Permanent jobs promised
Land area

Which document closes each gap

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.
