California’s Distribution Resources Plan Working Group [R. 14-08-013]

 California’s Distribution Resources Plan [R. 14-08-013]


The California Public Utilities Commission (CPUC) issued an Assigned Ruling on May 2nd 2016 (click here for full ruling) that established the Locational Net Benefit Analysis (LNBA) and Integration Capacity Analysis (ICA) Working Groups to monitor and provide consultation to the Independently Owned Utilities (IOUs) on the execution of Demonstration Projects A and B as defined in the Distribution Resource Plans. This website hosts all working group materials, presentations, meeting notices and draft reports for the LNBA and ICA Working Groups.  The Working Groups are managed by the IOUs and facilitated by More Than Smart.  Ultimate Oversight of the Working Groups is provided by the CPUC Energy Division.

IOUs submitted their final Demo A and Demo B Final Reports to the CPUC in advance of the December 31st deadline:

The ICA Working Group has submitted the following reports:

The LNBA Working Group submitted the following reports:

A June 7 ACR provided scope and schedule to the continued long-term refinement activities for ICA and LNBA. More Than Smart facilitated the compilation of two scoping documents  to help the Working Group initiate long-term refinement discussions.

The ACR also set deadlines for interim status reports.

  • August 31: Group I status report (ICA, LNBA)
  • October 31: Groups II, III, IV status report

A Final Decision (D. 17-09-026) was filed Sept. 26, 2017 on Track 1 DRP.
