End of the Blank Check: Massachusetts Mandates 100% Clean Power for Data Centers

Massachusetts became the latest state to force data centers to bring their own power, but this time there’s a twist. A new state mandate would require developers building data centers larger than 25 megawatts to provide clean power or pay into a ratepayer protection fund. This executive order, signed by Gov. Maura Healey, represents a stark departure from the pro-tech consensus that dominated state legislatures just a few years ago. Where states once competed fiercely to offer tax breaks and streamlined permits to attract cloud computing giants, they are now erecting barriers to protect local grids and ratepayers from the insatiable energy demands of artificial intelligence.

Under Healey’s order, data centers larger than 25 megawatts of peak demand will have to bring their own power and guarantee that it adheres to the state’s clean energy requirements. Healey would prefer that they generate the clean power on-site, too. If not, they’ll need to fund the construction of a new generation nearby or pay into a ratepayer protection fund. This "pay-to-play" model ensures that the cost of powering AI does not fall on residential consumers or small businesses. By forcing developers to internalize the cost of energy infrastructure, Massachusetts is effectively putting a price tag on the environmental impact of large-scale computation. The governor’s office clarified that data centers will be required to meet 100% of their electricity demand with clean energy generation, a standard far stricter than the state’s general clean energy standard, which mandates only 40% renewable sourcing by 2030.

Massachusetts is also directing communities to “avoid signing non-disclosure agreements,” according to the executive order. This transparency clause is a direct response to community backlash over secretive deals between towns and tech developers. For years, municipalities have signed NDAs that prevented them from disclosing the terms of data center leases, leaving residents in the dark about potential noise, traffic, and environmental impacts. By banning these agreements, Healey is empowering local governments to negotiate from a position of knowledge and accountability. To give regulators time to implement the new restrictions, the governor is pausing applications for a data center sales tax exemption that went into effect last month, hitting the brakes on a policy that was widely criticized as a giveaway to wealthy corporations.

With the new restrictions, Massachusetts becomes the third state in as many months to rein in data center development. In August, Texas Governor Greg Abbott announced that all new data centers in the state would need to submit to audits by the public utility commission and the grid operator, ERCOT. In July, New York’s governor stopped construction of new data centers 50 megawatts or larger. This tri-state crackdown suggests a growing regional consensus that the current pace of AI infrastructure growth is unsustainable without stricter oversight. Texas, traditionally a laissez-faire haven for energy-intensive industries, is now acknowledging the strain on its independent grid. New York, facing similar density and infrastructure challenges, has opted for a temporary moratorium to assess long-term impacts.

With public sentiment shifting against data centers, the tech industry is starting to push back. Pro-AI super PAC Leading the Future which is funded by Marc Andreessen, Ben Horowitz, and Greg Brockman is buying ads that seek to sway voters in battleground states ahead of midterm elections. The group argues that restricting data center growth will stifle American innovation and cede leadership in AI to China. They frame the issue as a choice between progress and stagnation, warning that excessive regulation will drive jobs and investment out of the United States. However, this narrative is increasingly clashing with local realities, where residents are seeing their electricity bills rise and their communities transformed by industrial-scale facilities.

The Massachusetts mandate sets a new benchmark for responsible tech development. It acknowledges that while AI offers tremendous potential, it cannot come at the expense of grid stability or environmental justice. By requiring 100% clean energy, the state is forcing the tech industry to innovate not just in software, but in energy production and storage. It may lead to more on-site solar and wind projects or investments in next-generation nuclear or geothermal solutions. But it will certainly make building data centers more expensive and complex.

For tech companies, the era of the blank check is over. They can no longer rely on state subsidies to offset their operational costs. They must now prove that their growth is sustainable, transparent, and beneficial to the communities that host them. If they cannot, they will pay the price literally. And for governors like Maura Healey, that is a price worth paying to protect their constituents from the hidden costs of the digital age.
