Interconnection Standards
Quick Summary
You can interconnect rooftop solar to Alabama Power's grid by submitting an application through PowerClerk and ensuring approval before installation; you'll need to comply with Southern Company's Interconnection Policy and Alabama Power's Technical Requirements Guidebook. You can apply a rate rider (RGB) to maintain grid backup power and may sell excess energy through Rate PAE (systems under 100kW) or Rate CPE (100kW and larger). Check local zoning rules and your homeowner's association before proceeding, and consider pairing solar with battery storage to address inconsistent sunlight.

Program Summary
Alabama does not have statewide interconnection standards. Southern Company, the parent company of Alabama Power Company, does have a policy on operation of distributed energy resources (DER) in parallel with the distribution system. The policy does not give explicit information on system size limits in relation to levels of review. The scope of any required system impact study is determined jointly by the DER owner and the utility. Following the system impact study, an interconnection equipment study may also be required. Incorporation of energy storage systems may require additional study.
