Bow Data Center (Merrimack Station site)

Bow, Merrimack County, NH

Granite Shore Power, a private operator, has announced Bow Data Center (Merrimack Station site), a data center project in Bow, NH. Reported capacity is 350 MW. Granite Shore Power, owner of the former Merrimack Station coal-plant site (343 acres) in Bow, filed a Viability Assessment Agreement with FERC in April 2026 for Eversource to study grid interconnection for a data center. The FERC filing describes 350 MW; a NH consumer advocate has separately referenced 'up to 200 MW' in discussions with officials, so exact capacity is unconfirmed. Very early stage: no site plan, permits, or named end-operator/tenant yet; officials declined to confirm the exact site. Gov. Ayotte has publicly opposed the project and it helped spur a legislative moratorium push in Sept 2026.
