EGI Wholesale Distribution & Rule 21 Export Applications

Customer Connections Online (CCO), hosted by Building and Renovation Services Online, is the new application system that replaces the interim Generator Interconnection Request online forms for Electric Generation Interconnection (EGI) export customers. CCO offers new and improved features that make it simple and intuitive to submit Generator Interconnection Request applications for Wholesale Distribution (Attachment 2), Rule 21 Export (Form 79-1145), and NEM2 over 1MW (Form 79-1174) customers.

It's easy: Submit your application anytime. You will receive a confirmation message that contains your application number.

PG&E strongly recommends preparing all information and materials before starting the online application; a Getting Started Guide has been prepared to assist you with this process. If the Interconnection Request is missing information or documents required to begin the generator interconnection process, PG&E will accept the application, but will deem it incomplete. PG&E will provide a written list of deficiencies to the designated representative provided in your request. Failure to submit subsequent information pursuant to the Wholesale Distribution (PDF, 1.7 MB) or Rule 21 (PDF, 7.5 MB) tariff will result in the withdrawal of the Interconnection Request.

Rule 21 Distribution Group Study Application Window

In accordance with PG&E's Rule 21 generator interconnection procedures, PG&E will open a Distribution Group Study (DGS) Application Window within the following schedule:

DGS application window schedule*

1st Application Window

2nd Application Window

*Application windows occur at the same time each year.

Interconnection Requests to be studied under the Distribution Group Study Process (PDF, 919 KB) shall either be (a) an Independent Study Process Interconnection Request that passed screen Q and failed Screen R for which the Applicant elects to continue to the next available Distribution Group Study, or (b) an Interconnection Request submitted during a Distribution Group Study Application window that passes Screen Q. Please refer to the Rule 21 link above for a description of Screens R and Q.

New Interconnection Requests for the Rule 21 Independent Study Process will NOT be accepted during the Distribution Group Study application window dates listed above.

Pursuant to California Public Utilities Commission Decision (D.) 19-03-103, PG&E has expanded the existing Screen Q exemption for net energy metering (NEM) facilities with net export less than or equal to 500 kilowatts (kW) by increasing the exemption size threshold to all NEM and inverter-based non-NEM projects with 1 Megavolt Amperes (MVA) or less nameplate capacity.

For projects that fail the Electrical Independence Test, PG&E may perform additional engineering analyses to determine the need for Reliability Network Upgrades, and in addition PG&E will:

  1. List all generation projects in the current queue that are adjacent to the proposed project.
  2. If current base-case is not complete, use last approved cluster base-case.
  3. If a cluster is ongoing, with Reliability Network Upgrades (RNUs) not yet finalized, compare pre-project base-case and post-project base-case loading, when necessary, to determine if there is/are any potential Network Upgrade(s) required.
  4. If a cluster is ongoing, with RNUs finalized, compare pre-project base-case and post-project base-case with RNUs considered and determine if the subject interconnection request triggers a change in scope for that RNU.
  5. Consult with the CAISO as necessary
