Renewable Customer-Generation Successor Tariff or Contract

Establishing a Successor Tariff or Contract Pursuant to Public Utilities Code 2827.1

Background

On October 7, 2013, Governor Brown signed Assembly Bill (AB) 327 (Perea) directing the Commission to develop a standard tariff or contract for eligible customer-generators with a renewable electrical generation facility no later than December 31, 2015. In developing the standard contract or tariff, Public Utilities (PU) Code 2827.1 requires the Commission to do the following:

  • Ensure that customer-sited renewable distributed generation continues to grow sustainably;
  • Include specific alternatives designed for the growth of distributed generation among residential customers in disadvantaged communities;
  • Ensure that the successor tariff is based on the costs and benefits of the renewable electrical generation facility;
  • Ensure that the total benefits of the tariff to all customers and the electrical system are approximately equal to the total costs;
  • Allow distributed generation projects sized to customer load that are greater than 1 MW in size to interconnect under reasonable charges if they do not have significant impact on the distribution grid; and,
  • Establish terms of service and billing rules for eligible customer generators, consistent with all other relevant statutory requirements.

For each large investor-owned utility, the successor tariff is to take effect either on July 1, 2017, or upon reaching the 5% program limit for NEM capacity set forth in the Public Utilities Code Section 2827, whichever is earlier.

Full text of AB 327 (Perea) is available here: http://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201320140AB327

For general questions about NEM or the successor tariff/contract, please contact Shannon O’Rourke at Shannon.O'Rourke@cpuc.ca.gov or (415) 703-5574.

Proceeding

In July 2014, the Commission adopted Rulemaking (R.) 14-07-002 to develop a successor to existing NEM tariffs, pursuant to Public Utilities (PU) Code Section 2827.1.  

To join this or any other proceeding’s service list, please visit our Service List page. For more information on how you can participate in this proceeding, please visit the Commission’s Public Advisor page.

Public Tool Documents

Energy Division has contracted with Energy and Environmental Economics, Inc. (E3) to develop a ‘Public Tool’ that will test various options for a successor to the existing net energy metering (NEM) tariffs, following PU Code 2827.1. 

The preliminary Public Tool schedule is available here. Further information related to the development of the Public Tool is provided below.

Final Version of the Public Tool

The Final Version of the Public Tool is available here.

Note: a previous version of the final public tool files included the word "FINAL" in the file names for the three public tool files. In order for the model to run, the word "FINAL" must be removed from the file names.

To run the model, the user should download and unzip all three excel files to the same folder and ensure that macros are enabled. Only the “Public Tool” should be open when executing the model. The cover sheet within the “Public Tool” guides the user through the relevant interfaces necessary to operate the model.

Questions regarding how to use the Final Version of the Public Tool should be emailed to Shannon O’Rourke at shannon.o’rourke@cpuc.ca.gov

The Energy Division Staff Paper Demonstrating how to use the Public Tool to Evaluate Options for a Successor to NEM tariffs in Compliance with AB 327 can be accessed here.

UPDATED Results Tables from Energy Division Staff Paper using REVISED Public Tool and REVISED Scenarios from July 20, 2015 ALJ Ruling: Updated Results Tables for the three policy scenarios that were examined in the Energy Division Staff Paper can be accessed here. These Results Tables are using the using the revised Public Tool and the revised Scenarios described in the July 20, 2015 ALJ Ruling Providing Further Instructions for Parties’ Proposals and Accepting Into the Record Certain Updates to the Public Tool.

Public Tool Updates and Questions on the Tool: Documentation on adjustments that were made to the Public Tool to produce the Final Version of the Public Tool and party questions on Public Tool functionality is available here. (updated as of 8/21/15)

Public Tool Model Runs from Updated Results Tables using REVISED Public Tool and REVISED Scenarios from July 20, 2015 ALJ Ruling: All of the model runs for the updated Results Tables using the revised Public Tool and the revised Scenarios described in the July 20, 2015 ALJ Ruling Providing Further Instructions for Parties’ Proposals and Accepting Into the Record Certain Updates to the Public Tool can be accessed here. Parties may use these files to view the complete model run results from each Scenario.

REVISED Public Tool Input Scenarios for Updated Results Tables: All of the input scenarios used to generated the updated Results Tables from the Energy Division Staff Paper using the revised Public Tool and revised Scenarios from the July 20, 2015 ALJ Ruling are available here. To load a scenario into the Final Version of the Public Tool, simply copy the desired scenario from its column in the excel sheet beginning at row 6, and paste it into a scenario column on the “Scenarios” tab of the Public Tool beginning at row 6. Then go to the “Results” tab and select the desired scenario using the “Load Inputs” button.

Input Scenarios and Modified Public Tools used in NEM Successor Tariff Party Proposals Submitted August 3, 2015 are available here.

Draft Version of the Public Tool

The draft version of the Public Tool is available here.

To run the model, the user should download and unzip all three excel files to the same folder and ensure that macros are enabled. Only the “Public Tool” should be open when executing the model. The cover sheet within the “Public Tool” guides the user through the relevant interfaces necessary to operate the model.

Questions regarding how to use the draft version of the Public Tool should be emailed to Shannon O'Rourke at Shannon.o’rourke@cpuc.ca.gov. Questions that have been received will be added to the Public Tool Question & Answer Document.
