2 Joint Project Overview PJM/NYISO Wheel Replacement Protocol Project Overview Why was the project started? What is the wheeling service that is currently in place? When does the replacement protocol have to be in place? What is the impact to Market Participants? ConEd notified involved parties of intention to terminate non-conforming wheeling service on April 28, PJM and NYISO are working jointly to develop a replacement protocol to address the operational, planning, and market impacts. The non-conforming wheeling service has historically been implemented by NYISO and PJM by modeling a fixed 1000 MW flowing from NYISO to PJM over the JK (Ramapo-Waldwick) interface and from PJM to NYISO over the ABC (Hudson- Farragut and Linden-Goethals) interface Current non-conforming wheeling service will end on April 30, New protocol must be in place for use on May 1, 2017 Primary impact to PSE&G and ConEd as facility owners No impact to OASIS/Energy Transaction processes 2

3 Background ConEd notified involved parties of intention to terminate nonconforming wheeling service on April 28, Current wheeling service will end on April 30, New protocol must be in place for use on May 1, PJM and NYISO are working on a replacement protocol. PJM Stakeholder approach: Operational topics will be addressed in Operating Committee Markets topics will be addressed in the Market Implementation Committee Planning topics will be addressed in the Planning Committee 3

4 Overview of PSE&G-ConEd 600/400 Contract PJM NYISO Wheel Overview Ramapo 1000 MW To Rockland (RECO) 1,000 MW from NYISO to PJM at the J and K interface 1,000 MW to NYISO from PJM at the A, B and C interfaces Hopatcong Waldwick HTP HVDC O66 Hudson 49 th Street Farragut 670 MW Linden 330 MW Goethals Branchburg Linden VFT 4

5 Current Protocol 61% of AC interchange and 80% of RECO load applied to the 5018 desired flow calculation 1,000 MW non-conforming wheel service Imported on the J & K Exported on the A, B, & C 5

6 Guidelines for New Protocol Supports reliable operation of the transmission system Effectively manages congestion across the region Provides for open access and utilization of the facilities to serve the public interest and provide benefit to consumers Does not hinder use of the facilities to respond to emergencies in real-time Preserves competitive market behaviors Minimize impacts to PJM and NYISO load 6

7 Considering a combination of two concepts: Proposed Protocol 1. Account for an Operational Base Flow as a starting point Natural system flows determined using EMS & PSS/e study applications Applied to the JK and ABC interfaces as a starting point for determination of Interface Target Flow Apply Interchange Percentage values on top of Operational Base Flow to determine Interchange Target Flow value. 2. Apply an Interchange percentage distribution: 5018: 32% JK: 15% ABC: 21% 7

8 Model Setup Input Existing Proposed RECO Load 80% on % on 5018 AC Interchange 61% 5018, 39% Western Ties 15% JK, 32% 5018, 21% ABC, 32% Western Ties Wheel 1000 In/out None Market Impacts: Proposed Options Market Impacts* Protocol Assumption Operational Base Flow MWs applied into PJM (JK interface) and out to NYISO (ABC Interface) PJM Simulated Market Impacts Productions Costs Congestion Costs *Utilized PROMOD Production Cost Simulation tool. Positive represents increase relative to existing Load Payments A 0/0 1.23% 2.14% 0.39% B -400 / % 1.80% 0.40% C / % 1.16% 0.40% 8

9 Additional Market Impacts NYISO interface definition Existing definition defined as 20% of Dunkirk + 80% Roseton See Appendix A for example Post Wheel definition to be determined Impacted by final Operations protocol and appropriate percentage allocation of AC interchange on the 5018, JK, and ABC interfaces M2M Impacts Existing M2M PAR Coordination on Ramapo PAR only for a subset of facilities with higher impact Post Wheel new/modified M2M PAR coordination anticipated on Ramapo, Waldwick, and Farragut PARs 9

10 Whitepaper NYISO created and posted a Whitepaper for the Wheel Replacement effort on their website /Paper%20on%20ConEd%20PSEG%20Wheel%20Replacement%20Proposal_v_1_FINAL.pdf PJM reviewed the whitepaper and offered edits Second version of the whitepaper will be posted jointly with NYISO and will include PJM perspective Final version expected in September 10
