5. DRP Process DRP Roadmap and ICA workshops conducted November 9 and 10, 2015 Comments on DRP Roadmap Staff Proposal submitted ICA workshop report circulated Comments on ICA workshop report will be solicited with LNBA comments after this workshop Ruling on ICA, LNBA, Demo A & B expected end of Q1 2016 DRP Scoping Memo released January 27, 2016 5

6. Workshop Purpose and Goal This workshop is being held pursuant to ALJ Julie Fitch’s ruling of January 8, 2016. The purpose and objective of the workshop are to: ruling Examine in detail utility proposals for Locational Net Benefits Analysis (LNBA) methodology and Demonstration Project B (Demo B) that were set forth in their Distribution Resources Plans (DRP) filings of July 1, 2015; Provide an opportunity for parties to present alternatives, modifications, or improvements to the proposals; To inform Commission consideration of utility LNBA methodology and Demo B proposals. 6

7. What is the Locational Net Benefits Analysis (LNBA)? Quantifies the avoided cost of integration of DER Specifies a set of “value components” that capture avoided cost either at the bulk system level, or locally within the distribution system and a method for calculating each of those costs Resulting Information to be made available in online maps 7

8. Why are we doing it? (One of) a set of tools that quantify the benefits of DER that can be deployed at a particular location. Moving toward building the capability to compare portfolios of DERs as alternatives to traditional grid infrastructure. Improve the distribution planning process to enable higher penetration of DER, and provision of grid services by DER, as an alternative to traditional utility infrastructure investments. 8

9. From Guidance (Optimal Location Benefit Analysis aka Locational Net Benefit Analysis) Specifies the net benefit that DERs can provide in a given location. Net benefits methodology based on the Commission approved E3 Cost- Effectiveness Calculator, but enhanced to explicitly include location-specific values Consistent across all three Utilities 9

10. Value Components from Guidance Avoided Sub-transmission, Substation and Feeder Capital and Operating Expenditures: Avoided Distribution Voltage and Power Quality Capital and Operating Expenditures: Avoided Distribution Reliability and Resiliency Capital and Operating Expenditures: Avoided Transmission Capital and Operating Expenditures: Avoided Flexible Resource Adequacy (RA) Procurement: Avoided Renewables Integration Costs: Any societal avoided costs which can be clearly linked to the deployment of DERs Any avoided public safety costs which can be clearly linked to the deployment of DERs 10

11. Demo Project B (Guidance) Commission-approved Optimal Location Benefit Analysis (aka LNBA) methodology is performed for one distribution planning area (DPA) Include a detailed implementation schedule. DPA to study shall include, at minimum, –one near term (0-3 year project lead time) and –one longer term (3 or more year lead time) distribution infrastructure project for possible deferral. 11
