Improving

Connecticut Siting Council (CSC, CGS §16-50i et seq.) has jurisdiction for all electric generation facilities >1 MW. CSC can affirm or revoke municipal zoning orders — effectively can preempt local zoning. CSC must give consideration to municipal regulations but is not bound by them. Projects ≤1 MW: local zoning commission governs. Projects on agricultural land >2 MW: DEEP NDDB review + CT Dept of Agriculture letter required. Agricultural land with prime farmland soils: applicant must demonstrate project will not materially affect prime farmland status; DoAg must certify to CSC. DEEP Construction Stormwater General Permit required for all solar construction. ISO-NE interconnection required statewide.
