Massachusetts has become the third U.S. state in three months to impose new restrictions on data center expansion after Governor Maura Healey issued an executive order holding developers responsible for providing the clean energy needed by large facilities. The order applies to data centers with peak demand exceeding 25 megawatts.
Under the order, these facilities will be required to provide energy that complies with the state's clean energy requirements. Healey prefers this energy to be generated on-site, but developers may instead fund the construction of new generation capacity near the center or pay into a fund designated to protect electricity consumers. This means that a data center's consumption will not be treated as a burden that can be placed entirely on the grid or on other customers.
Requirements Exceeding the General Clean Energy Share
Massachusetts relies on a clean energy standard established in state law, which requires the electricity sector to use approved sources such as wind, solar, and hydropower at rates that increase over time. By 2030, these sources must account for at least 40% of total electricity under the general standard.
However, the governor's office clarified that data centers will be required to cover 100% of their electricity needs with clean energy generation. This represents a significant tightening compared with the general minimum and clearly establishes that compliance is not limited to purchasing electricity from existing sources, but is tied to providing clean generation to meet demand.
Transitional Measures and Local Transparency
The executive order directs local communities to avoid signing nondisclosure agreements related to data center projects. The state has also temporarily suspended applications for a sales tax exemption for data centers, which took effect the previous month, to give regulators time to implement the new restrictions.
The extracted text did not specify a complete timeline for implementing all the mechanisms or details on calculating amounts that might be paid into the electricity consumer protection fund. Consequently, how the clean generation requirement will be implemented and how coverage of the full demand will be demonstrated remain issues that will require further regulatory clarification.
Why Does This News Matter?
The decision changes the economics of building large data centers in Massachusetts. Developers now face not only the cost of the site and digital infrastructure, but may also have to build or fund clean generation capacity or bear a financial contribution designated to protect customers. This directly affects cloud computing and artificial intelligence projects that rely on facilities with high energy consumption, and it also increases the importance of site selection and the availability of clean electricity sources before development begins.
The shift follows a period in which technology companies and data center developers received incentives to attract their facilities to states. Now, however, these projects are facing growing public opposition, while authorities seek to address concerns related to energy costs, pressure on grids, and the transparency of local decisions.
In August, Texas Governor Greg Abbott announced that new data centers would be subject to review by the Public Utility Commission and the electricity grid operator ERCOT. In July, the governor of New York halted the construction of new data centers with capacity of 50 megawatts or more. The timing of these measures indicates that the rapid expansion of infrastructure needed for artificial intelligence has become a regulatory and political issue, rather than a business decision separate from electricity grid management.
