Massachusetts Mandates Clean Power for Large Data Centers, Following Texas and New York

Massachusetts Leads New Trend in Data Center Regulation

Massachusetts has joined Texas and New York in implementing new restrictions on data center development, with Governor Maura Healey signing an executive order on September 9, 2026, that mandates large data centers source 100% of their electricity from clean generation. This comparison highlights how Massachusetts's approach, requiring facilities over 25 megawatts to build onsite clean generation, fund new generation nearby, or pay into a ratepayer protection fund, differs from the recent actions taken by Texas and New York.

Comparing State Approaches to Data Center Regulation

The recent actions by Massachusetts, Texas, and New York highlight varying state-level strategies to manage the rapid growth of data centers. While all three states have implemented restrictions, their specific requirements and triggers differ. Understanding these distinctions is crucial for developers and operators in the industry.

Massachusetts's Clean Energy Mandate

Massachusetts's executive order focuses directly on clean energy sourcing. Data centers exceeding 25 megawatts of peak demand are required to meet 100% of their electricity needs from clean generation. This can be achieved through onsite clean generation, funding new generation nearby, or contributing to a ratepayer protection fund. The order also includes provisions to prevent communities from signing non-disclosure agreements with developers and temporarily halts applications for data center sales tax exemptions. Notably, this 100% clean energy requirement is more stringent than the state's general clean energy standard, which aims for at least 40% from approved sources by 2030.

Texas's Audit Approach

In August, Texas initiated audits of data center operations. While the specific details of these audits are not fully outlined in the provided information, this action indicates a regulatory focus on existing or planned facilities within the state. Texas's approach appears to be a review and oversight mechanism rather than a direct mandate for clean energy sourcing or development halts.

New York's Construction Halt

New York implemented its own restrictions in July, specifically halting construction for data center facilities that are 50 megawatts or larger. This measure directly addresses the physical expansion of very large data centers, potentially to manage energy consumption or other environmental impacts. Unlike Massachusetts's clean energy mandate, New York's action is a direct pause on new large-scale development.

Implications for Data Center Development

The actions taken by Massachusetts, Texas, and New York signal a shifting regulatory landscape for data centers across the United States. For developers, these new rules introduce additional considerations for site selection, energy strategy, and financial planning. The Massachusetts mandate, in particular, sets a high bar for clean energy integration, potentially increasing operational costs or requiring significant investment in renewable energy infrastructure.

The political context surrounding these regulations is also notable. A pro-AI super PAC named Leading the Future, funded by prominent figures like Marc Andreessen, Ben Horowitz, and Greg Brockman, is actively purchasing ads to influence midterm voters. This suggests a broader engagement with AI-related infrastructure and its societal implications.

Conclusion

The executive order in Massachusetts, requiring large data centers to source 100% clean power, marks a significant development in state-level regulation of digital infrastructure. Alongside actions in Texas and New York, it underscores a growing trend towards stricter oversight of data center energy consumption and environmental impact. For companies planning or operating data centers, these evolving regulations necessitate careful strategic planning to ensure compliance and sustainable growth. The specific requirements in each state — from clean energy mandates to construction halts and audits, mean that the optimal location and operational strategy will depend heavily on the individual needs and capabilities of each data center project.
