Text of Letter

“Under the authority provided for in the Commission’s Rules of Practice and Procedure, Section I 6.6, the compliance deadline for Smart Inverter Phase II communications requirements, pursuant to Resolution E-4832, OP 2 and 4, and for Phase III Functions I and 8, pursuant to Resolution E-4898, OP 2.a, is extended to August 22, 2019.

This deadline extension letter is in response to the letter of November 19, 2018 from the California Solar & Storage Association (CALSSA). CALSSA requested a six-month extension of the deadline to comply with the Smart Inverter Phase [I communications requirements ordered in Resolution E-4832 and an equivalent delay in the deadline for compliance with Phase 11J Functions I and 8, as established by Resolution E-4898 (the “deadline extension request” or “CALSSA request”). This request would extend the deadline from February 22, 2019 to August 22, 2019.

CALSSA served its request on the service list of Rulemaking (R.) 11-09-01 I and of R.17-07-007. Southern California Edison and Pacific Gas & Electric responded to the CALSSA request affirming their non-opposition to the deadline extension request.

Due to the complex technical and procedural nature of the rollout of Rule 21 smart inverter capabilities, the complete background and discussion of the CALSSA request have been appended to this letter; see Appendix A.

We find that the extension requested by CALSSA is necessary. Additional time will provide both industry and the utilities more opportunity to smoothly roll of this rule change.

This deadline extension request applies only to the Smart Inverter Phase II communications requirements and to Functions 1 and 8 of the Smart Inverter Phase III requirements. It does not affect Smart Inverter Phase III Functions 5 or 6, which, pursuant to Resolution E-4898, OP 2.a, will be required for all inverter-based generating facilities as of February 22, 2019.

In conclusion, the compliance deadline for Smart Inverter Phase II communications requirements, pursuant to Resolution E-4832, OP 2 and 4, and for Phase III Functions 1 and 8, pursuant to Resolution E-4898, OP 2.a, is extended to August 22, 2019.”
