New Smart Inverter Requirement (July 26, 2018)

Starting July 26, 2018, the CPUC requires that PG&E only accept applications with UL 1741 SA compliant smart inverters with the default setting for Volt Var set to "reactive power priority" for interconnection requests utilizing inverter technology. For more information about this requirement, visit https://www.pge.com/nem2program. Note: PG&E's interconnection portal will be periodically updated (as needed) to reflect the current list of approved inverters.

  1. Listed on the CEC inverter website (this applies to Net Energy Metering/NEM applications only)
  2. Capable of being set to reactive power priority per UL-1741 SA certification, AND
  3. Set with default to operate in "reactive power priority" mode

Please note NEM2 changes:

  • Customers applying to interconnect a NEM2 project less than or equal to 1MW will be required to pay an application processing fee of $145.
  • NEM2 projects that are participating in the Single-family Affordable Solar Homes (SASH) program are exempt from the application processing fee.
  • Customers applying to interconnect a NEM2 project over 1MW will be required to pay for all interconnection study costs, including an $800 Interconnection Request fee per Rule 21 Section E.2.c.

An invoice will be provided once the application is submitted and reviewed by PG&E.

A PG&E representative will contact you to discuss the next steps.

If you are applying to interconnect a NEW solar or wind generator less than 30 kW, please apply to the Standard NEM online interconnection tool.

Interconnection Portal Guide

PG&E recommends preparing all information and materials before starting the application. If the Interconnection Request is missing information or documents, PG&E will accept the application, but will deem it incomplete and provide a written list of deficiencies to the designated representative provided in your request.
