Massachusetts requires large data centers to supply their own clean power

Massachusetts has become the latest US state to move against data center development, and it has attached an unusually direct condition: large facilities have to arrive with their own clean electricity. According to TechCrunch, Governor Maura Healey has signed an executive order requiring developers building data centers with peak demand above 25 megawatts to secure power that complies with the state's clean energy requirements, or pay into a ratepayer protection fund.

How the mandate works

Under the order, qualifying facilities must guarantee that their power meets the Massachusetts clean energy standard already written into state law. Healey would prefer that the generation happen onsite; where it does not, developers must either help fund construction of new generation nearby or contribute to the ratepayer fund.

The standard itself tightens over time, requiring a rising share of electricity to come from approved sources such as wind, solar and hydro — at least 40 percent by 2030. But the governor's office clarified to TechCrunch that data centers face a stricter target: they will be required to match 100 percent of their electricity demand with clean generation.

Two supporting measures round out the order. Communities are being directed to avoid signing non-disclosure agreements, a practice that has often kept proposed projects hidden from residents until deals are effectively final. And to give regulators room to work out how the restrictions will be implemented, Healey has paused applications for a data center sales tax exemption that took effect the month before.

A fast reversal in state policy

The Massachusetts order makes it three states in three months. In August, Texas Governor Greg Abbott announced that all new data centers in the state would face audits by the public utility commission and the grid operator ERCOT. In July, New York's governor halted construction of new data centers rated at 50 megawatts or larger.

The turnaround has been quick. TechCrunch notes that only a few years ago, states competed to attract data centers with incentives; today, politicians are eager to show voters they are addressing public opposition to the buildout.

The industry pushes back

The tech sector is not accepting the shift quietly. According to TechCrunch, a pro-AI super PAC called Leading the Future — funded by Marc Andreessen, Ben Horowitz and Greg Brockman — is buying advertising aimed at voters in battleground states ahead of the midterm elections.

Why it matters

Massachusetts is sketching a new template for regulating cloud infrastructure. Rather than only limiting where or when data centers can be built, the order ties a facility's treatment, including access to a sales tax exemption, to the emissions profile of the electricity it consumes — and sets the bar at 100 percent clean power, well above the incremental targets the standard imposes on others. If additional states copy the approach, the economics of adding US data center capacity change materially, since operators may need to finance generation projects, not just server halls, before a campus can come online. The sequence of moves in Massachusetts, Texas and New York also shows how quickly the political climate has swung from incentive packages to mandates and moratoriums, and the ad campaign from a well-funded AI PAC signals that the argument will now be carried to voters as well as regulators.
