State-level permits & approvals
DNREC (Dept of Natural Resources and Environmental Control) regulates utility-scale solar under the Coastal Zone Act and Regulations for Renewable Energy Generating Facilities. Projects ≥25 MW in regulated area require DNREC permit; projects in Coastal Zone require Coastal Zone Act permit. Public Service Commission (PSC) may review larger facilities. County land use process also required: New Castle County: County Council land use approval; Kent County: levy court/county council process; Sussex County: Board of Adjustment CUP or Sussex County Council approval. Delaware has no statewide solar preemption; local approvals required in addition to state permitting. Very limited agricultural land (small state, ~2,000 sq mi); most utility-scale opportunity in Sussex County (largest DE county, most agricultural land). All DE in PJM / Delmarva Power (DLCO) zone. Delaware has aggressive RPS and generally receptive political climate for solar — one of most solar-friendly states in PJM territory.
