Massachusetts Orders Data Centers Over 25MW to Bring Their Own 100% Clean Power

Governor Maura Healey signed an executive order requiring any data center exceeding 25MW of peak demand to bring its own power and meet 100% of electricity demand with clean generation — a far tighter bar than the state's baseline 40% by 2030 mandate. Developers must prioritize onsite generation or fund nearby clean-power builds, communities are told to avoid NDAs, and data-center sales-tax exemption applications are paused. Massachusetts becomes the third state in three months to tighten data-center rules after Texas and New York.
