Net Energy Metering Revisit - Rulemaking (R.) 20-08-020
The model was updated on December 23, 2021 to fix a formatting bug in the Results worksheet.
Dec. 17, 2021: The comment period on the proposed decision was extended. See “Proceeding Schedule” below.
The Commission committed in Decision (D.) 16-01-044 to later review the NEM successor (or NEM2) tariff, citing interactive, yet unresolved, policy movements within the Commission, but outside the scope of R.14-07-002. Accordingly, the Commission adopted an Order Instituting Rulemaking on August 27, 2020 to revisit the existing NEM tariffs.
The major focus of this proceeding will be on the development of a successor to existing NEM2 tariffs pursuant to the requirements of California Assembly Bill 327 (2013, Perea). The proceeding's scope also includes the review and potential modification of all NEM tariff schedules, and issues related to consumer protection.

Issues in Scope
As described in the Scoping Memo, the issues to be determined in this proceeding are:
1. What guiding principles (including those related to Assembly Bill 327 (2013, Perea), equity, environmental goals, and social justice) should the Commission adopt to assist in the development and evaluation of a successor to the current net energy metering tariff?
2. What information from the Net Energy Metering 2.0 Lookback Study should inform the successor and how should the Commission apply those findings in its consideration?
3. What method should the Commission use to analyze the program elements identified in Issue 4 and the resulting proposals, while ensuring the proposals comply with the guiding principles?
4. What program elements or specific features should the Commission include in a successor to the current net energy metering tariff?
5. Which of the analyzed proposals should the Commission adopt as a successor to the current net energy metering tariff and why? What should the timeline be for implementation?
6. Other issues that may arise related to current net energy metering tariffs and subtariffs, which include but are not limited to the virtual net energy metering tariffs, net energy metering aggregation tariff, the Renewable Energy Self-Generation Bill Credit Transfer program, and the net energy metering fuel cell tariff.
7. What additional or enhanced consumer protections for customers taking service under net energy metering and/or the successor to the current net energy metering tariff should be adopted by the Commission?
These guiding principles, adopted in D.21-02-007, will assist the Commission in the development and evaluation of proposals for a successor to the current NEM tariff.
(a) A successor to the net energy metering tariff should comply with the statutory requirements of Public Utilities Code Section 2827.1;
(b) A successor to the net energy metering tariff should ensure equity among customers;
(c) A successor to the net energy metering tariff should enhance consumer protection measures for customer-generators providing net energy metering services;
(d) A successor to the net energy metering tariff should fairly consider all technologies that meet the definition of renewable electrical generation facility in Public Utilities Code Section 2827.1;
(e) A successor to the net energy metering tariff should be coordinated with the Commission and California's energy policies, including but not limited to, California Senate Bill 100 (2018, DeLeon), the Integrated Resource Planning process, Title 24 Building Energy Efficiency Standards, and California Executive Order B-55-18;
(f) A successor to the net energy metering tariff should be transparent and understandable to all customers and should be uniform, to the extent possible, across all utilities;
(g) A successor to the net energy metering tariff should maximize the value of customer-sited renewable generation to all customers and to the electrical system; and
(h) A successor to the net energy metering tariff should consider competitive neutrality amongst Load Serving Entities.

E3 White Paper
As part of the new proceeding, the CPUC commissioned Energy and Environmental Economics, Inc. (E3) to author a white paper on potential successors to the NEM2 tariff. The white paper was released publicly on January 28, 2021, and can be downloaded here. E3 presented its analysis in a workshop on February 8, 2021. Slides used during the workshop are available here.
The white paper represents E3's perspective on a framework that can meet the statutory requirements for the NEM program. It was entered into the record of R.20-08-020 and parties to the proceeding were instructed to discuss it in their proposals for a successor to the current NEM program.
Parties submitted proposals for the successor to the current NEM tariff on March 15, 2021. The proposals are available in the Documents tab of the R.20-08-020 docket. An online workshop was held on March 23-24, 2021, to allow parties to present on their proposals, and other parties and stakeholders to ask questions. Recordings of the workshop are available here: Day 1 | Day 2. Due to a technical error, the recording for Day 1 omits a portion of the workshop. At 2:31.42 (approximately 2.5 hours in), the recording skips from the Natural Resources Defense Council's time to the joint investor-owned utilities' time.
