Electrical permit and CPS Energy DG interconnection path

City of San Antonio residential permit guidance says projects may require electrical permits based on scope and that homeowners must use licensed trade contractors for new electrical components. For a residential battery energy storage system, CPS Energy also treats batteries as part of its Distributed Generation contractor and interconnection workflow: installers submit DG materials such as a one-line diagram, site plan, and elevation drawing, and Battery Rewards eligibility requires completing CPS Energy's DG application and interconnection process. Battery storage work should follow the BuildSA electrical permit path and CPS Energy DG interconnection review before operation.
