Power and water

The 350 MW figure is the load size in a Viability Assessment Agreement between PSNH (Eversource) and Granite Shore Power, LLC. Under it, PSNH studies a 'potential load interconnection of a 350 MW facility' to its transmission system, at the customer's sole cost. This is a study agreement, not an interconnection award. NH's Consumer Advocate separately said Eversource staff mentioned a developer considering 'up to 200 MW' in Bow.

Notes on the record

This is the former Merrimack Station coal plant site, which stopped coal generation in 2025; its two small kerosene combustion turbines are still listed as active. Granite Shore Power owns 343 acres there, in an industrial zone. That is the owner's site holding, not a confirmed data-center footprint, so the land area is left blank. The FERC agreement says only 'a 350 MW facility' and never says data center. The data-center use comes from a Bow town official confirming high-level talks, as reported by NHPR and the Concord Monitor. The end developer has not been named and no application has been filed with the town, so confidence is 'reported'. Coordinates are the EIA plant point, so precision is approximate.

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.
