Transmission Technical Standards for Load and Non-SDG&E Owned Generator Interconnection or Generation Interconnection Handbook

The SDG&E Interconnection Handbook is applicable to all generators and loads 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 and loads connected to the SDG&E portion of the ISO Controlled Grid, and as such the handbook may be modified or superseded from time to time.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 Interconnection Handbook are deemed consistent with Good Utility Practice and Applicable Reliability Standards.  The SDG&E Interconnection Handbook includes:

  • Metering Requirements
  • Protection and Control Requirements
  • General Operating Requirements
  • Operating Procedures
  • Energization and Synchronization Requirements
