State-level permits & approvals

2024 Massachusetts Climate Act (signed Nov 21, 2024): historic reform of siting and permitting. Large projects (>25 MW generation or >100 MWh storage): Energy Facilities Siting Board (EFSB) consolidates state and local review into single master permit; 15-month deadline for EFSB decision. Small projects (≤25 MW / ≤100 MWh): municipalities retain permitting authority under new streamlined process (225 CMR 29.00 promulgated Feb 27, 2026; effective immediately). 12-month deadline for municipal decisions on small clean energy projects. MGL Ch.40A §3 (Massachusetts Zoning Act): zoning ordinances cannot prohibit or unreasonably regulate solar energy systems — long-standing solar protection for sub-threshold projects. DOER site suitability scoring framework; community benefit plan requirements for larger projects. ISO-NE interconnection required statewide.
