  1. December 19, 2013 | Reliability committee meeting Mariah Winkler Engineer, Resource Analysis & Integration 2017-2018 Capacity Commitment Period Evaluation of Non-Price Retirements Submitted between 9/27/2013 – 10/6/2013
  2. FCA #8 Non-Price Retirement Details The Non-Price Retirement Request (NPR) submission window for the 2017-2018 CCP opened on June 3, 2013 and closed on October 6, 2013 98 NPRs were submitted 12 have been discussed and approved at the August & October Reliability Committee (RC) meetings 86 will be discussed today Today’s meeting shall focus on the below resources that submitted NPRs between 9/27/2013 and 10/6/2013
  3. Overview of the Reliability Analysis The reliability analysis for NPRs is done in accordance with ISO New England Planning Procedure No. 10 (PP-10) – Planning Procedure to Support the Forward Capacity Market (FCM) Obligates the ISO to analyze the thermal, voltage and, if appropriate, the stability impacts of NPRs Assumptions for the analysis specified in Appendix A of PP-10 A reliability need constitutes a rejection of the NPR Consultation with Transmission Owners and ISO Operations Included as a supplement to this presentation, as part of today’s meeting materials, are the following: The Needs Assessments for each of the submitted NPRs discussed today Presentation Appendix with detailed Brayton Point Station Transmission Operability Analysis slides Contains Critical Energy Infrastructure Information
  4. Transmission Operability Analysis Assumptions Transmission topology as prepared for the 2017-2018 Capacity Commitment Period Load modeled at the 2013 CELT 90/10 peak New England Control Area load for summer 2017 All Existing Capacity Resources modeled at their Summer Qualified Capacity for the 2017-2018 Capacity Commitment Period 20% of the peaking generation resources assumed unavailable For the ME Load Zone, 7.0 MW assumed unavailable out of 35 MW (3 Resources) For the NH Load Zone, 16.6 MW assumed unavailable out of 83 MW (5 Resources) For the VT Load Zone, 26.0 MW assumed unavailable out of 130 MW (9 Resources) For the CT Load Zone, 304.8 MW assumed unavailable out of 1,524 MW (36 Resources) For the SEMA Load Zone, 51.8 MW assumed unavailable out of 259 MW (7 Resources) For the WCMA Load Zone, 55.4 MW assumed unavailable out of 277 MW (9 Resources) One critical resource in the electrical vicinity of the respective NPR assumed out-of-service (OOS)
  5. Transmission Operability Analysis Assumptions, cont’d Demand Resources modeled at their assumed Availability Factors as presented at the September 18, 2013 RC meeting Active demand resources were modeled via a load reduction spread across their respective Dispatch Zones Passive demand resources were modeled via a load reduction spread across their respective Load Zones
  6. NPR Transmission Operability Analysis Norwalk Harbor Station
  7. NPR Transmission Operability Analysis Results Voltage Results Results of the N-1 and N-1-1 voltage analysis indicated that there are no voltage violations in the local study area caused by the retirement of Norwalk Harbor Station Thermal Results Results of the N-1 and N-1-1 thermal analysis indicated that there are no thermal violations in the local study area caused by the retirement of Norwalk Harbor Station ISO recommends that the NPRs for these resources be accepted
  8. NPR Transmission Operability Analysis Citizens Block Load
  9. NPR Transmission Operability Analysis Results Voltage Results Results of the N-1 voltage analysis indicated that there are no voltage violations in the local study area caused by the partial NPR of Citizens Block Load Thermal Results Results of the N-1 thermal analysis indicated that there are no thermal violations in the local study area caused by the partial NPR of Citizens Block Load ISO recommends that the partial NPR for Citizens Block Load be accepted
  10. NPR Transmission Operability Analysis EnerNOC Demand Response NPRs
  11. Summary of EnerNOC Demand Response NPRs EnerNOC, Inc. submitted 76 NPRs totaling approximately 554 MW *Totals include adjustments for Availability Factors (varies by type and/or zone) and Distribution Losses (5.5% Gross-Up)
  12. NPR Transmission Operability Analysis Results Voltage Results Results of the N-1 voltage analysis indicated that there are no voltage violations in the respective local study area caused by the retirement of the capacity associated with the EnerNOC Demand Response NPRs Thermal Results Results of the N-1 thermal analysis indicated that there are no thermal violations in the respective local study area caused by the retirement of the capacity associated with the EnerNOC Demand Response NPRs ISO recommends that the NPRs for these resources be accepted
  13. NPR Transmission Operability Analysis Brayton Point Station
  14. NPR Transmission Operability Analysis Results N-1 (Brayton Point Station OOS) Voltage Results Results of the N-1 voltage analysis indicated that there are no voltage violations in the local study area caused by the retirement of Brayton Point Station Thermal Results Results of the N-1 thermal analysis show thermal violations with Brayton Point Station retired Based on the operating restrictions at Brayton Point Station, testing showed there is a reliability need for at least Brayton PT 1 & 3
  15. NPR Transmission Operability Analysis Results, cont’d N-1-1 (Brayton PT 1 & 3 In-Service) Voltage Results Results of the N-1-1 voltage analysis indicated that there are no voltage violations in the local study area caused by the retirement of Brayton PT 2 & 4 Thermal Results Results of the N-1-1 thermal analysis show thermal violations caused by the retirement of Brayton PT 2 & 4 The testing showed there is a reliability need for Brayton PT 1-4 Overloads remained on the system with other combinations of Brayton Point Station Units ISO recommends that the NPR for the Brayton Diesels 1-4 Incremental resource be accepted and the NPRs for Brayton PT 1-4 be rejected
  16. NPR Transmission Operability Analysis Results – Interstate Reliability Project Sensitivity The Interstate Reliability Project (IRP) is one of the major transmission Projects that are part of the New England East-West Solution (NEEWS) Designed to address weaknesses in the east/west and west/east transmission of power across CT, RI, and MA while also resolving CT and RI import issues The certified transmission projects for the 2017-2018 Capacity Commitment Period included only a portion of the IRP specifically the addition of a second 345 kV transmission line (3271 line) between Lake Road and Card Street A sensitivity transmission operability analysis was performed which modeled the entire IRP to understand its impacts on the retirement of Brayton Point Station should additional portions of the IRP be certified and accepted by the ISO in accordance with Market Rule 1, Section III.12.6 in the future
  17. NPR Transmission Operability Analysis Results – Interstate Reliability Project Sensitivity, cont’d N-1 (Brayton Point Station OOS) Voltage Results Results of the N-1 voltage analysis indicated that there are no voltage violations in the local study area caused by the retirement of Brayton Point Station Thermal Results Results of the N-1 thermal analysis show a thermal violation caused by the retirement of Brayton Point Station The testing showed there is a reliability need for at least Brayton PT 1
  18. NPR Transmission Operability Analysis Results – Interstate Reliability Project Sensitivity, cont’d N-1-1 (Brayton Point Station OOS) Voltage Results Results of the N-1-1 voltage analysis indicated that there are no voltage violations in the local study area caused by the retirement of Brayton Point Station Thermal Results Results of the N-1-1 thermal analysis show thermal violations caused by the retirement of Brayton Point Station The testing showed there is a reliability need for at least Brayton PT 1
  19. Advisory Vote Planning Procedure No. 10, Section 7.5.2 states “The Reliability Committee shall provide formal input and advice to the ISO through an advisory vote regarding the review of Non-Price Retirement Requests prior to the ISO making a formal determination regarding the reliability impacts of a given Non-Price Retirement Request where, pursuant to Section III.13.2.5.2.5.(a)(i) of Market Rule 1, notification to the requesting Lead Market Participant will be made within 90 days of the submission of the Non-Price Retirement Request.” The ISO is seeking an advisory vote today on the review of Norwalk Harbor Station, Citizens Block Load, EnerNOC Demand Resources > 5 MW, and Brayton Point Station NPRs
