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

Are you installing a larger self-generation system (more than 30-kilowatts)? Or, do you want to apply energy credits produced by a single generator to several electric accounts? Use the program resources below to interconnect solar, wind, fuel cells, batteries or multiple technology-generating systems to the PG&E energy grid.

Understand the self-generation programs

Learn about qualifications, documents needed for applications, interconnection requirements, costs and other considerations for the following 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).
