Find resources for interconnecting larger systems to the PG&E grid

When you’re installing a larger self-generation system (more than 30-kilowatts) or want to apply energy credits produced by a single generator to several electric accounts, the information on this page can help you with your project. You can use the resources to interconnect these types of systems to the PG&E energy grid.

  • Solar
  • Wind
  • Fuel cells
  • Batteries
  • Multiple technology-generating systems

Learn about the various interconnection programs

We put together some essential resources to assist contractors who are applying for interconnection for larger self-generation programs. The resources include key information about:

  • Qualifications
  • Documents needed for applications
  • Interconnection requirements
  • Costs
  • Additional considerations

Access the following resources when applying for interconnection of a larger system:

Interconnection Program Information

Understand the Different Programs

  • Expanded Net Energy Metering (NEMEXP). This program is for residential and commercial generators that are 30 kilowatt (kW) to 1 megawatt (MW). Visit Expanded Net Energy Metering (NEMEXP).
  • Net Energy Metering Aggregation (NEMA). This program allows a single customer with multiple meters on the same property, or adjacent or contiguous properties, to use renewable generation to serve the aggregated load behind all eligible meters. Visit Net Energy Metering Aggregation (NEMA).
  • Net Energy Metering Virtual (NEMV). This program allows a building owner or manager to interconnect a renewable generator to serve multiple tenant meters that are individually metered. The program enables the receipt of bill credits to offset each benefiting account bill. Visit Virtual Net Energy Metering (NEMV).
  • Net Energy Metering for Fuel Cells (NEMFC). This program has an optional rate schedule for customers who install fuel cell generators. Visit Net Energy Metering for Fuel Cells (NEMFC).
  • Net Energy Metering Multiple Tariff (NEMMT). This program is for customers who operate a NEM-eligible generator in conjunction with a non-export or NEM fuel cell generator. Visit Net Energy Metering Multiple Tariff (NEMMT).
  • Non-Export. This interconnection program is available to all types of generator technologies and sizes when energy is not exported to the grid or when uncompensated export is acceptable. Visit Non-Export.
  • Energy storage. As a generator, energy storage can be interconnected under Non-Export or can be paired with a NEM system, if it is applied for under the NEM Multiple Tariff (NEMMT) program. Visit Energy Storage.
  • Renewable Energy Self-Generation Bill Credit Transfer (RES-BCT). This program is for local governmental entities that want to use renewable generation to serve onsite load and allocate the remaining credits to other facilities within the same local government. Visit Renewable Energy Self-Generation Bill Credit Transfer (RES-BCT).
