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 information on this page to find out how to interconnect the following types of systems to the PG&E energy grid:
Review the following program resources to get key information about eligibility, documents needed for applications, interconnection requirements, costs and other considerations.
Expanded Net Energy Metering (NEM2EXP). This program is for residential and commercial generators that are sized greater than 30 kilowatt (kW). Visit Expanded Net Energy Metering (NEMEXP).
Net Energy Metering Aggregation (NEM2A). 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 (NEM2V). 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 (NEM2-MT). This program is for customers who operate a NEM-eligible generator in conjunction with another NEM-eligible generator, non-export generator, or NEM fuel cell generator. Visit Net Energy Metering Multiple Tariff (NEMMT).
Option S Rate Modifier for Storage. Option S is a special rate modifier for customers with storage who are on either a B-19V, B-19 or B-20 rate. There is a 50MW cap on Option S enrollment under each of the three rate schedules. For more information on Option S, visit Option S cap tracker.
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 interconnection.
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 (NEM2-MT) 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).
