Learn about exporting power
Discover resources for generating and selling unused power
Wholesale generators are customers who generate and sell unused power to the wholesale market through our distribution or transmission network. This page contains a necessary outline of the interconnection process and studies that can help you connect and sell your project's power to the grid.
Learn about the types of wholesale generation interconnection projects
- Distribution. New projects interconnect at line voltages less than 60 kilovolts (kV). Visit Distribution. Access the online application. Visit Online Application.
- Transmission. New projects interconnect at line voltage 60 kV and higher. Visit Transmission. Access the California Independent System Operator (CAISO) Application. Visit CAISO Application (DOCX, 142 KB).
- Qualifying facilities. Existing facilities interconnected with PG&E's transmission or distribution system produce wind, hydroelectric, biomass, waste, cogeneration or geothermal energy. Visit Qualifying Facilities.
Understand the 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. Following are the 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.
