Submit a small generator interconnection application (FERC Order 2023 SGIP) through the SDG&E interconnection portal for a distribution-connected battery storage project

Steps

1. Navigate to the SDG&E Interconnection Map portal at interconnectionmapsdge.extweb.sempra.com to identify the candidate substation polygon and verify queued generation at the proposed point of interconnection
2. Prepare the FERC Order 2023-compliant SGIP application package: complete the SDG&E Interconnection Request form for projects under 5 MW (Small Generator); include one-line diagram, site plan, equipment specifications (inverter model with UL 1741-SB certification), and the required $500 application deposit
3. Submit the application through the SDG&E online portal; receive a confirmation with assigned Queue Number and confirm the application has entered the FERC Order 2023 cluster queue cycle
4. Track the Feasibility Study completion (typically within 45 business days under FERC Order 2023 timelines); download the study results from the portal which will include identified network upgrades and estimated costs
5. Execute the Interconnection Facilities Study Agreement within the deadline posted in the feasibility study results to remain in the queue; missing this deadline results in automatic withdrawal
6. After System Impact Study approval, coordinate with SDG&E's Distribution Engineering for the Interconnection Agreement (IA); the IA must reference IEEE 1547-2018 smart inverter settings required for the specific circuit
