SDG&E Solar Interconnection: Timeline and Tracker
San Diego Gas & Electric covers a compact but busy service area, and its interconnection process follows the familiar California IOU pattern. The smaller footprint does not make the permit-to-PTO gap any less real for installers.
Who is SDG&E, and where does it operate?
SDG&E is an investor-owned utility serving San Diego County and southern Orange County — roughly 4,100 square miles. As with PG&E and SCE, its net metering and interconnection rules sit under CPUC tariffs, including the current net billing framework.
The interconnection process
- 1.Installers usually submit the SDG&E interconnection and net metering application online after finalizing the design and equipment selection.
- 2.SDG&E reviews the submission and returns an interconnection agreement for standard residential systems. Installers commonly describe a multi-week typical range, with incomplete documentation being the usual reason a project slips.
- 3.Once the local jurisdiction signs off on inspection, SDG&E finalizes interconnection and issues PTO so the system can be energized.
Timelines above reflect what installers commonly report, not guaranteed or regulated processing times. Confirm current requirements directly with SDG&E.
Documents typically required
- •Completed SDG&E interconnection / net metering application
- •Single-line diagram
- •Inverter and module specification sheets
- •Signed interconnection agreement
- •Final building and electrical inspection sign-off
The gap between permit approval and PTO
Even in SDG&E’s relatively contained territory, projects routinely sit finished-but-not-energized while the utility works through its PTO step. That waiting period is easy to lose track of when the permit is already closed. PermitClock keeps the SDG&E interconnection clock visible next to the permit clock so nothing stalls unnoticed.
