State Permitting Process
No statewide solar siting law. Utility-scale solar regulated at county level by Board of Supervisors via discretionary zoning or conditional use permits. Counties retain full authority to approve, condition, or deny projects with no state preemption. MPSC oversees electric utilities; no formal solar siting review below 300 MW. FERC/MISO or SERC interconnection governs projects >20 MW.
State Incentives
No state RPS or SREC market. Solar equipment property tax exemption (Miss. Code Ann. §27-31-101). Net metering under MPSC Rule 29 (capped at 150% of 12-month avg usage; interconnection fee may apply). Federal ITC (30% under IRA 2022) is primary incentive. No state solar grant or loan programs. TVA Green Power Switch applies in TVA-served northeast MS counties.
