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.

Reported lifecycle history

  1. Proposed

    PSNH filed a Viability Assessment Agreement (VSA-PSNH-001) with Granite Shore Power, LLC at FERC for a potential 350 MW load interconnection. A Bow town official later confirmed high-level talks about a data center at the site, but no application has been filed with the town.

    Underlying source

Source notes

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 no land area is recorded. 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. As of October 2026, the end developer has not been named and no application has been filed with the town, so the record is marked reported. Coordinates are the EIA plant point, so precision is approximate.

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.
