Massachusetts Data Centers Must Now Use Clean Energy

TL;DR: Massachusetts Governor Maura Healey signed an executive order requiring any data center over 25 megawatts of peak demand to supply 100% of its own clean energy or pay into a new ratepayer fund, according to TechCrunch and EnergyNow. Developers must also secure local approval before seeking state construction permits — a real hurdle layered on top of an already high-cost state.

I signed off on more than 1,000 QA jobs aboard the USS Jefferson City, a nuclear fast-attack submarine. On that boat, nothing got certified until it was verified. Apply that here.

Downside first: this order isn't a ban. It's a cost the state just moved onto the developer's side of the ledger. Verify before you trust a pitch deck's assumption that this state's compliance path stays cheap.

What did Healey's order actually require?

The order applies to any data center that exceeds 25 megawatts of peak electricity demand. Utilities generally get until 2030 to hit a 40% clean-energy floor under the state's existing standard, according to Dataist.ai. Large data centers don't get that runway: Healey's office clarified that they must meet 100% of demand with clean generation, per TechCrunch, and a developer that misses the bar pays into a new ratepayer-protection fund instead, per EnergyNow.

One more piece sits inside the same order. Municipalities are told to avoid signing nondisclosure agreements with developers, according to Dataist.ai. Separately, and before this order, Healey paused applications in June for the data-center sales-tax exemption she had signed into law in 2024, according to EnergyNow.

What does this mean if you have money near this trade?

Massachusetts already sees far less data center investment than other states because of high energy and real estate costs, according to EnergyNow. This order adds a real cost on top of that: self-generation, a financed offsite clean-power project, or a payment into the ratepayer fund. Pick one, and the deal's numbers move.

If you hold or are evaluating exposure to a data center developer, REIT, or private credit deal with Massachusetts assets, underwrite it the same way I underwrite anything: sponsor, structure, fees, liquidity, then upside. Here, structure comes first. Which of those three routes is the sponsor actually planning to take, and what does it do to the project's cost of capital? A sponsor who hasn't answered that question hasn't finished the deal.

How does Massachusetts compare to other states?

Massachusetts is the third state in three months to put new conditions on data center construction, and each state has picked a different test, according to Dataist.ai.

State	Trigger	What it requires
Massachusetts	Over 25 MW peak demand	100% clean energy, or pay into a ratepayer fund
New York	50 MW or larger	New construction halted, per TechCrunch
Texas	—	A regulatory review, per Dataist.ai

There is no single national standard forming yet. A deal underwritten for one state's rules doesn't automatically clear the bar in the next one. If you're comparing a Massachusetts project to a project in Europe's data center buildout, run the state's own rule. Don't run an assumed average.

What mistakes do I see investors make here?

The first mistake is treating this as a ban. It isn't. It's a cost reallocation, and well-capitalized developers with a real clean-power plan will still build. The second is assuming this is federal policy that applies everywhere. It's a state order, and three states have already written three different rules. The third is skipping past the sales tax exemption pause: a project that penciled out with that exemption may not pencil out the same way while it's suspended, according to EnergyNow.

FAQ

Are data centers being built in Massachusetts? Yes, but less than in most other states. High energy and real estate costs have kept Massachusetts well behind other regions on data center investment, according to EnergyNow.

Why don't data centers already use clean energy? Most large energy users only have to meet the state's slower, industrywide clean-energy timeline. Healey's order carves out large data centers and asks them to hit the bar on their own balance sheet, instead of waiting for that timeline, according to TechCrunch.

What is Massachusetts' clean energy goal? The state's broader clean energy standard requires at least 40% clean generation, wind, solar, and hydro among the approved sources, by 2030, according to Dataist.ai. Large data centers face a stricter 100% requirement instead.

Why are Massachusetts electric bills a concern here? Rising demand from AI data centers is raising concerns nationally about electricity bills, grid strain, and water use, according to EnergyNow. That's my read, not something the order states: the new ratepayer protection fund looks aimed at that bill-strain complaint.

What should you do with this today?

Don't skip to the return projection. Ask the sponsor which compliance route they're actually using: onsite generation, financed offsite clean power, or the ratepayer fund payment. Get the cost of that route in writing before you evaluate anything else. Verify before you trust the deck.
