Types of projects

There are three types of wholesale interconnection projects:

Distribution

New projects interconnect at line voltages less than 60 kilovolts (kV). Learn more about Electric Generation Interconnection (EGI).

Transmission

New projects interconnect at line voltage 60 kV and higher. Access the California Independent System Operator (CAISO) Application. Visit CAISO Application (DOC).

Qualifying facilities

Existing facilities interconnected with PG&E's transmission or distribution system produce wind, hydroelectric, biomass, waste, cogeneration or geothermal energy. Learn more from Electric Services Handbooks.

Federal and state regulations

The Federal Energy Regulatory Commission (FERC) and California Public Utilities Commission (CPUC) are the agencies that provide regulation for energy markets. For any interconnection voltage or method of selling power, an Interconnection Agreement with PG&E is necessary to meet the regulations set forth by these agencies.

Reasons for the regulations:

Safety

All electrical generating systems are potentially dangerous if they are not operated properly. If your system connects to our electric grid, safeguards for protecting you, our personnel, other customers and the public must be in place.

 

Reliability

We’re dedicated to providing reliable power to our customers. If a fault or trip occurs on your generation system, we must be able to isolate the problem to ensure that we can continue to provide reliable service to our other customers.

Educational resources

Our Electric Generation Interconnection (EGI) team offers guidance and education about the interconnection process to customers, contractors, developers and local governments. We can assist you in managing the process and help ensure a safe, reliable interconnection to our electrical system. 

If you have questions about wholesale generation, email us at wholesalegen@pge.com

For general inquiries about the interconnection process and timing, contact our Solar Service Center at 1-877-743-4112. The Solar Service Center can assist with all general questions.

Fast Track Review or Detailed Study

If you are dissatisfied with the efforts of PG&E to meet the timelines of the Fast Track Review and/or Detailed Study for a valid Interconnection Requests (Rule 21, Section F1.1.d.), contact the PG&E-appointed Rule 21 Ombudsman:

Disputes

To initiate an official dispute under Section K.2. of Rule 21, submit your request to Rule21Disputes@pge.com and “cc” or send a copy to Rule21.Disputes@cpuc.ca.gov.

 

To participate in the Expedited Dispute Resolution Process under Section K.3., please refer to Expedited Interconnection Dispute Resolution (ca.gov)

Installing an AC Disconnect Switch

If you install an inverter-based generator, consider also installing an AC Disconnect Switch, which only isolates your generator, not your load. Your inverter, PV arrays and other equipment are maintained. The AC Disconnect Switch allows us to isolate your generator from our distribution system without interrupting service to your facility or residence.

You are not required to include an AC Disconnect Switch when your facility has a single-phase, self-contained electric revenue meter. A 0-320-amp panel is an example of this type of meter, which is used by 98 percent of our customers.

If you chose not to install an AC Disconnect Switch, we may remove your revenue meter to isolate your generator from the electric distribution system. Removing the revenue meter helps us meet our operating needs, respond to emergencies and maintain our system. If we remove the revenue meter, your facility or residence loses electrical service.

Our AC Disconnect Requirement for Distributed Energy Resources or Distributed Generation policy applies to:

  • Inverter-based interconnections that have a transformer-rated meter. Examples of transformer-rated meters include all meter panels or switchboards that use potential or current transformers. 
  • Inverter-based interconnections that have a three-phase, self-contained meter or a transformer-rated meter. Examples of transformer-rated meters include all meter panels or switchboards that use potential or current transformers. 
  • Non-inverter-based generators, including rotating or machine-based generators, regardless of whether the service-meter configuration is transformer-rated or self-contained. 
  • Inverter and non-inverter-based generators that do not have overcurrent protection at the point of interconnection.
  • Special situations in which generators affect our service to our customers.

Animals, locked gates or other obstacles must not block access to the meter area. The meter must remain accessible at all times. You can arrange to provide our personnel with secure access. 

 

Updates to PG&E AC Disconnect policy

Our policy was revised to help answer your requests and support the California Solar Initiative. The policy includes photovoltaic (PV) fuel cell and inverter-based rotating machine technologies.

 

Check with your local government to determine if an AC Disconnect Switch is required to obtain a final electric permit for an installed photo voltaic fuel cell system or other inverter-based rotating machine technologies.
