This bill amends RSA 674 by introducing a new subdivision specifically addressing data centers. It defines a "data center" as a facility primarily used for the storage, processing, management, and transmission of digital data, while excluding smaller facilities that do not exceed 25 percent of the gross floor area of all on-site buildings and are used solely for the enterprise functions of the property owner without leasing data services to third parties.

The bill grants municipalities the authority to permit data centers within zoning districts designated for commercial or industrial use, subject to local land use regulations. Additionally, it allows planning boards, with the approval of the local legislative body, to adopt necessary regulations regarding data centers. The act will take effect 60 days after its passage.
