For a few years, cities and states competed to lure data centers with tax breaks, cheap land and fast permits, treating the sprawling buildings as an economic prize. On September 9, Massachusetts turned the logic on its head: the state said the biggest new data centers will have to bring their own clean power, or pay up.
Governor Maura Healey signed an executive order requiring any data center with peak demand above 25 megawatts to supply its own electricity in line with the state’s clean-energy standards. A facility that cannot do so must either pay to build new generation nearby or pay into a fund that protects ratepayers.
The order goes further. It tells communities to avoid signing confidentiality agreements about data-center projects, a measure aimed at the secrecy that has surrounded many deals. And it suspends the sales-tax exemption for data centers that took effect just last month, pausing it while regulators write the detailed rules the order calls for.
Massachusetts is the third state to tighten the terms on data centers, following others that have moved to restrict where the facilities can be built or what they must contribute. The change is swift: states that once courted the industry are now writing conditions designed to blunt its demands on the grid.
The reason is power. Data centers, and the artificial-intelligence workloads that fill them, consume electricity at a scale that has begun to strain grids in several regions. A single large facility can draw as much power as a small city, and the projects are arriving faster than transmission lines and generators can be added.
For ratepayers, the concern is who pays for the upgrades. When a data center hooks into a local grid, the cost of reinforcing that grid is often spread across ordinary customers, who see higher bills to support infrastructure built for someone else’s servers. The Massachusetts order is an attempt to shift that cost back onto the data center itself.
Across the country, the AI boom has sent utilities scrambling. Grid operators in Virginia, Texas and elsewhere have reported waiting lists of large customers seeking connections, and projections of data-center demand have been revised upward again and again. Massachusetts, with high electricity costs and a constrained grid, has been watching that wave approach.
For the industry, the new rule raises the bar on where it can build cheaply. Operators have favored states with abundant, inexpensive power, and adding a requirement to finance new clean generation narrows the list of viable sites. Analysts said the policy could push some projects toward states with friendlier terms, and others toward self-generation.
The confidentiality provision is a small but telling detail. Many data-center deals have been negotiated in secret, with communities learning the scale of a project only after commitments were made. By urging communities to refuse nondisclosure agreements, the governor is trying to make sure residents know what is being built before it is too late to object.
The pause on the sales-tax exemption is similarly pointed. The exemption was meant to attract investment; suspending it while the rules are written sends a message that the state’s courtship phase is over and the regulatory phase has begun.
The politics are not hard to read. Data centers have become an easy target for officials who want to show they are protecting consumers from a booming industry backed by some of the richest companies in the world. Requiring tech giants to pay for their own power is popular, and the order is as much a statement as a regulation.
Industry groups have warned that the requirements could slow the buildout of the computing capacity the AI economy depends on. If every large facility must finance its own clean generation, the argument goes, fewer will be built, and the economic benefits, the jobs and the investment, will go elsewhere.
The state’s answer is that the benefits have not been flowing to the people paying the costs. Data centers employ relatively few workers once built, and their main local impact, an enormous draw on the grid, is felt by everyone. The order reflects a judgment that the industry’s value to the state has not matched its burden.
What the final rules say will determine how binding the order is. The suspension of the tax break and the clean-power requirement still need detailed implementation, and the industry will have a chance to shape the outcome. But the direction is set, and it points the same way as in the two other states that have already moved.
For the companies building these facilities, the message is clear enough. The era of the welcome mat is closing. In Massachusetts, the price of a data center now includes the power it burns, and the state has decided the company, not the customer next door, should pay it.
