Interconnection With SDG&E-Owned Electric Transmission Facilities
SDG&E Transmission-Level Interconnection Handbook
The SDG&E Transmission-Level Interconnection Handbook is applicable to all generators, loads, and transmission equipment interconnecting to the SDG&E transmission system that are not otherwise subject to SDG&E Rule 21.
It describes technical and operational requirements for wholesale generators, loads, and transmission equipment connected to the SDG&E portion of the ISO Controlled Grid, and as such the handbook may be modified or superseded from time to time.
SDG&E's standards contained in the Transmission-Level Interconnection Handbook are deemed consistent with Good Utility Practice and Applicable Reliability Standards. The SDG&E Transmission-Level Interconnection Handbook includes:
- Interconnection Process Overview
- Metering Requirements
- Protection and Control Requirements
- Substation Requirements
- Transmission Line Requirements
- General Operating Requirements
- Operating Procedures
- Energization and Synchronization Requirements
Financial Security Instruments
