Interconnection Standards

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.
