Rankin County, MS — Solar Development Risk Assessment

Local solar ordinance barriers, board sentiment, and utility policies that affect development timelines and risk.

Risk Grade
Good
Second-best risk profile in Jackson metro: high income, fastest population growth in region, strong C&I solar activity, and pro-development supervisors. Entergy Mississippi resistance to large-scale DG and absent solar ordinance are the primary limiting factors.

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.

Development Activity

Active/Completed Projects
Multiple C&I rooftop installations in Brandon and Flowood commercial corridors. Residential rooftop solar growing significantly with new construction. Several commercial developments in Pearl have explored solar. No confirmed large utility-scale ground-mount.
Denied/Withdrawn Projects
No confirmed denials on record.
