Final Issue 10/11 Proposal  Discussion (Gridworks, et al.) 2. Clean Up  This will be the final discussion of Issues 6/10/11 10/31: Final Report Filed Led by Energy Division Schedule

https://gridworks.org/initiatives/rule-21-working-group-2/ Issue 9 What conditions of operations should the Commission adopt in interconnection applications and agreements to allow distributed energy resources to perform within existing hosting capacity constraints and avoid triggering upgrades? Draft Issue 9 Proposal https://gridworks.org/initiatives/rule-21-working-group-2/

https://gridworks.org/initiatives/rule-21-working-group-2/ Issue 10 How can the Commission coordinate the Integration Capacity Analysis and each Utility’s Rule 21 processes with the Rule 2, Rule 15, and Rule 16 processes in order to improve efficiency of the overall interconnection process? This is a coordination issue at this time. However, modifications to Rules 2, 15, or 16 will be addressed if necessary Overview of Issue Scope (Gridworks) Issue 10 Memo Goals for Today: Brainstorm cross over issues between Rules Hear CALSSA presentation Strategize Proposal development https://gridworks.org/initiatives/rule-21-working-group-2/

https://gridworks.org/initiatives/rule-21-working-group-2/ Issue 10 Brainstorming Cross Over Issues Between Rules From SDG&E: Can a list be created that identifies which areas in one Rule’s processes could potentially see improved efficiencies via better coordination with processes in another Rule? The list should: identify cross-over steps between processes; proposed coordination efforts; proposed modifications, including those stemming from the integration of ICA results and those exogenous to ICA integration; and identify whether issues and proposals are relevant to all utilities. Today’s Goal: Work through at least one example and assign homework for fleshing out a full list. https://gridworks.org/initiatives/rule-21-working-group-2/

Rule 10 Cross-Over Example Issue Cross-over Step Proposed Coordination Effort(s) Proposed Modification Relevant to All Utility Example 1 Example 2

https://gridworks.org/initiatives/rule-21-working-group-2/ Issue 10 CALSSA Proposals 1. If special facilities are needed, start the Rule 2/15/16 process concurrently with the start of interconnection review.    2. Have a common ID number. 3. Create timelines of a maximum of 60 days for design and estimating and a maximum of 60 days for construction for all upgrades below the substation. https://gridworks.org/initiatives/rule-21-working-group-2/
