Optimal Location Values & Methodology
Facilitated Discussion
Context: AB327 Distribution Resources Plan
• Identifies optimal locations for the deployment of Distributed Energy Resources (DERs)
• DERs include distributed renewable generation, energy efficiency, energy storage, electric
vehicles, and demand response
• Evaluates locational benefits and costs of DERs based on reductions or increases in local
generation capacity needs, avoided or increased investments in distribution infrastructure,
safety benefits, reliability benefits, and any other savings DERs provide to the grid or costs
to ratepayers
• Proposes or identifies standard tariffs, contracts, or other mechanisms for deployment
of cost-effective DERs that satisfy distribution planning objectives
• Proposes cost-effective methods of effectively coordinating existing commissionapproved programs, incentives, and tariffs to maximize the locational benefits and
minimize the incremental costs of DERs
• Identifies additional utility spending necessary to integrate cost-effective DERs into
distribution planning
• Identifies barriers to the deployment of DERs, including, but not limited to, safety
standards related to technology or operation of the distribution circuit in a manner that
ensures reliable service

Distribution Planning Process Alignment to

Facilitated Discussion
Potential DPP Alignment Map for CPUC, CAISO, CEC
Refer to Lorenzo’s Handout

DPP Process Alignment for CPUC, CAISO, CEC
• The new DPP should align with the LTPP-TPP-IEPR timeline
• Main points to consider:
• When is it optimal to have a new DRP, i.e., the final result of the biennial DPP, to
feed into the other processes? That is, where on the alignment timeline do we
want the DPP to conclude?
• What are the key process steps of the DPP, what is the sequence in which they
must be performed, and what inputs do they require from other processes?
• Currently, first DRP due in July 2015. If July 2017 is the next deadline then:
• DRP would provide useful and timely input to the IEPR demand forecast, which is
planned to be released in draft form in September 2017 and finalized by
December 2017.
• Likely that July 2015 DPR will not be as informative for the 2015 IEPR, still we
should consider to what extent it will inform that forecast.
• CPUC, CECS, and CAISO will collaborate between September-December 2017 to
develop “assumptions and scenarios” for TPP and LTPP for cycles beginning in
January 2018.
Developed in consultation with Lorenzo Kristov (CAISO)

1H 2015 MTS WG Scope (proposed)
Facilitated Discussion
MTS WG Purpose & Objectives (based on July 2014 Workshop)
• Purpose:
• Provide an open, voluntary stakeholder forum to discuss core issues toward finding common
ground regarding the evolution of California’s distribution system and the seamless integration of
DER to meet customers’ needs and public policy. The results of the discussions will be for the
benefit of the participants and will be made public without specific participant attribution.
• Objectives:
 Define common parameters for the development of distribution planning scenarios for utilities
to properly stress test plans and to achieve a measure of comparability among the different
plans.
 Identify and define the integrated engineering-economic analysis required to conduct
distribution planning in the context of AB 327 requirements.
 Define the potential grid end-states in the context of existing plans/roadmaps and identify the
considerations regarding grid evolution to meet customers’ needs and California’s policy
objectives.
1H 2015
• Define the scope and parameters of an operational/DER market information
exchange to facilitate an open planning process and enable R&D efforts.
• Define distribution services associated with identified DER values including
performance requirements.
• Define new distribution operational functions (DSO) and related integration
technologies (vendor neutral) to create “node-friendly” open grid
