Louisiana’s commission rule (LPSC General Order dated 09-19-2019 (Docket R-33929), Distributed Generation Rule, incl. Standard Interconnection Agreement) does not bind municipal utilitys; City of Erath sets its own interconnection policy. We confirm its form on the first project. Electric cooperatives are bound. Municipal utilities (e.g. Lafayette Utilities System) are not LPSC-jurisdictional and set their own policies; New Orleans follows City Council rules.
