On September 8, 2026, Massachusetts Governor Maura Healey issued Executive Order 658: Establishing Requirements for Responsible Data Center Development and Operations in Massachusetts to Protect and Support Ratepayers, Communities, and the Environment (the “Order”).

Through the Order, Governor Healey implemented permitting and regulatory standards for Massachusetts data centers that exceed 25 MW of peak electricity demand. The Order references and incorporates elements of the Healey Administration’s previously issued Statement of Expectations for Responsible Data Center Development and Operations in Massachusetts released on June 25, 2026 (the “Framework”).

The Framework provided initial guidance for data center developers seeking sales and use tax exemptions and addressed energy supply, energy efficiency, air quality, water use, coordination with labor, community benefits, economic development and project transparency.
