Smart Smart Inverter & Reactive Power Priority Inverter & Reactive Power Priority Implementation Implementation Industry Implementation Discussion and Planning 6/04/2018
Agenda Purpose and Objective Smart Inverter History Presentation SI and Reactive Power Implementation Plan Presentation Action Items
Purpose and Objective Ensure industry understanding of near and future smart inverter implementation requirements Collaborate among all stakeholders on most effect way to support new requirements with focus on near terms requirements but accounting for long term requirements Draw a starting proposal to meet near term requirements including: Roles and responsibilities Timelines Determine next steps or next working meeting(s) to finalize the proposal What steps or actions the inverter industry need to take What steps or actions do the IOUs need to take What steps or actions does the Energy Commission/CEC need to take
Smart Inverter History Decision 14-12-035 (Dec 18, 2014) Order the CA IOUs to implement the Smart Inverter Phase I requirements adopting the recommendations from the Smart Inverter Working Group (SWIG) Implementation date of December 31, 2015 or 12 months after the date Underwriters Laboratories (UL) approves the applicable standard, UL 1741 Supplemental A (SA) Included Dynamic Volt-Var Operation Applying the Active Power Priority Decision 16-06-052 (Jun 23, 2016) Order the CA IOUS to implement Smart Invert Phase II communication Protocols and Phase III advanced functions Implementation Date of 9 months following SunSpec Alliance Communication Protocol Test Standards Resolution E-4898 (April 26, 2018) Establishes effective dates for each of the eight phase III advanced inverter functions Functions # 1, #5, #6 and #8 9 months following SunSpec Alliance Communication Protocol Test Standards Function #2 and 3 Earlier of December 2019 or Approval of IEEE1547.1 Function #4 and #7 12 months after approval of a nationally recognized standard ED issued a Staff Proposal (July 27, 2017) Proposing to modify Rule 21 to incorporate reactive power priority IOU Filed tier 2 ALs (December 28, 2017) - Proposing the Rule 21 modification to become effective nine moths following approval of the Als. Resolution E-4920 (April 26, 2018) Approves the modification of Rule 21 requiring the inclusion of reactive power priority effective three months following the resolution

Smart Inverter Implementation Timeline SWIG WORK Implementation Schedule Today 2013 2014 2015 2017 2017 2018 2019 2019 Future Recommendations(2/28/2015) Priority Changes to Reactive Power Phase II, Phase III functions #1, #5, #6, #8 Recommendations(Jan 2014) SWIG Phase III Recommendations Phase III functions #4, #7 (12 Phase I - Volt /Var Active Power SWIG Commences Its Work months after standards are Phase III functions #2, #3 Phase I (September 9, 2017) Priority ( July 26, 2018) (December 2019) SWIG Phase II January 2013 SWIG Phase I approved) (March 2017) (February 22, 2019) Alignment with National Standards TBD
CEC Listing Support On Phase I Implementation Added: Identifies Phase I Capabilities Requirements Listing Input into IOU Tools Meet Renewable Goals Happy Customers Enables Expedited Approvals
Reactive Power Priority (Manufacturers) Not ALL inverters are certified for both active and reactive priority under the UL-1741SA certification process How will inverters be identifies as being certified for reactive power priority? Letter from the NRTL? Will it be in the technical information sheet? Will it be on the inverter faceplate? How will inverters manufactures inform CEC that their UL-1741SA listed inverters are certified for reactive power priority Suggestion: Inverter manufacturers to send listing of all their inverters which are certified with reactive power priority along with NRTL supporting documentation (perhaps just a letter?) How quickly can the inverter manufacturers inform CEC that their UL-1741SA listed inverters are certified for reactive power priority Inverter which do not have this certification will not be allow to interconnect for new applications starting 7/26/2018
Reactive Power Priority (CEC) Can a new column be added as done for phase I? How can the CEC update their listing to account for inverters with reactive power priority? Discuss other ideas This column would have all the certified attributes (RPP, Phase II, Phase III, etc.) which become effective over time as shown on (Slide 3) What is the minimum date by which inverters have to submit the information in order to have the listing updated to meet the implementation time 7/26/2018?
Reactive Power Priority (IOUs) Can the utilities update their interconnection tools for new requirements in time for implementation? Goal Keep him happy Keep him happy If not implemented properly, customers will not be happy Input into IOU Tools Happy Customers Enables Expedited Approvals Can this change/update be completed by the implementation date (7/26/2018)?
