Alabama’s commission rule (No statewide interconnection rule or net metering statute found; utility-specific policies (Alabama Power: Southern Company Interconnection Policy, DER Technical Interconnection Requirements Guidebook, Rate Rider RGB, Rate PAE/CPE)) does not bind municipal utilitys; City of Piedmont sets its own interconnection policy. We confirm its form on the first project. Municipal utilities and cooperatives (many TVA distributors in north Alabama; PowerSouth members in south) set their own interconnection/buyback policies.
