Local county zoning permit: conditional use or special exception at county level; no uniform statewide solar permitting standard. PPRP (Power Plant Research Program, MD DNR): environmental review for generating facilities ≥70 MW; PSC CPCN required for projects ≥70 MW. Projects <70 MW: county-level permitting only. No statewide preemption of local solar ordinances. Net metering: systems up to 2 MW (residential up to 2× annual load). All MD in PJM territory. Maryland has the largest solar carve-out in the U.S. at 14.5% by 2028 (MD Code, PUC §7-703).

Maryland Renewable Energy Portfolio Standard (RPS): 50% by 2030; solar carve-out 14.5% by 2028 — drives strong SREC demand. Maryland SREC market: PSC-administered; ~$50-80/SREC 2023-2024 for Tier 1 Maryland SRECs. Maryland Solar Access Program (Brighter Tomorrow Act 2024): $750/kW up to $7,500 for income-qualifying residential customers. Maryland Community Solar: community solar program active statewide.

No confirmed utility-scale solar projects on public record as of Mar 2026.

No confirmed Maryland PSC CPCN denial or county-level rejection on record for Charles County. HB 1036/SB 931 (eff. Jul 1 2025) Renewable Energy Certainty Act: limits county authority to deny ≥1 MW solar — preempts local ordinances more restrictive than state standards (≤100 ft from property line; ≤150 ft from dwelling; ≥5 MW not in Planned Growth Areas).
