Sequence and Potential Dates for Market Trials (dates subject to change while in Planning phase) May 2025 June 2025 July 2025 Aug 2025 Sep 2025 Oct 2025 Nov 2025 Dec 2025 QSE Attestation 9 months before Trials. 2 months 1-2 months 2 months 1 month Open-loop RTC SCED (QSE offers, SCED non- binding award/dispatch) RTC QSE Submission Testing (Submit COP, RT AS Offers, DAM Virtual AS, Outages for ESRs) Closed-loop RTC SCED (QSE offers, SCED binding award and dispatch for 2-3 instances of 2- 4 hours) Transition to Go-Live Upon completion of testing, confirmation of ERCOT and market readiness for Go-Live. RTC QSE Telemetry Testing/Check-out (Individual QSE testing of UDSP, New ramp rates, ESR telemetry) 2-3 months Day-Ahead Market (Non-binding DAM using QSE offers at least 2 times) 1-2 months 4 Public
Plans for Meetings and Review Cycles Reminder of RTC+B Program Scope RTC Key Principles were approved to lay foundation of NPRR1007-1013 Consolidated Key Principles: https://www.ercot.com/files/docs/2020/04/01/RTC_Key_Principle_Quick_Reference.docx Library of Key Principles: https://www.ercot.com/mktrules/puctDirectives/rtCoOptimization Battery Key Topic Concepts approved to lay foundation of NPRR1014 https://www.ercot.com/mktrules/keypriorities/bes RTC State-of-Charge accounting in NPRR1204 Objective is to present concepts or issues that need to be resolved for an effective implementation. Coordinating timelines for interface requirements and testing, Providing the forum for any analysis or policy decisions (such as parameter values) Coordinating market readiness and cutover activities, Review draft Revision Requests or other artifacts necessary to successfully implement the program within the identified timeframes, and discussing other details as needed. Lessons learned from RTCTF to avoid being delayed in decisions: Meeting #1: Initial concept presented by ERCOT staff Meeting #2: Comments and alternatives presented by MPs Meeting #3: RTCTF consensus achieved or escalated to TAC for a vote to decide the matter. 5 Public

Summary of Resolved Issues Resolved Tab of Issues Workbook: Resolved Issues Source Id 17 Issue to resolve RUC Capacity Short Calculations with SOC Resolution or next steps TAC approval of RUC Capacity Whitepaper at April 2024 TAC. ERCOT to submit NPRR in May to support whitepaper. RTCBTF endorsement of approach: Given that Hydro Resources operating in synchronous condenser mode are not dispatched by SCED, ERCOT proposes setting the Mitigated Offer Cap for all Hydro Resources to RTSWCAP. This will be done in protocol and verifiable cost manual by 1) setting the O&M value in the MOC to RTSWCAP and 2) Setting the heat rate to 0 MMBtu/MWh. ERCOT 2023 Verifiable Cost Manual (Change for on-line hydro Resources per Key Principle 1.3(3)) 4 RTCTF issue 7 Public

RTCBTF Next steps - - June 12- Next RTCBTF Wrapping up limited series of RTC+B Technical Workshops (April-June 2024) - Target audience, vendors and IT development/implementation staff (sent to RTCBTF and TWG) RTC+B Technical Workshop - April 18, 2024: 1:00 PM 4:00 PM : Overview of ICCP Telemetry/EMS SCADA/AGC changes & ICCP Configurations for parallel testing. RTC+B Technical Workshop - May 6, 2024: 1:00 PM 4:00 PM : Finalize approach on ICCP configuration approaches for parallel testing and transition. RTC+B Technical Workshop - May 15, 2024: 1:00 PM 4:00 PM : Market Interfaces design specifications (submissions - External API/Market Manager, notifications, and reports) RTC+B Technical Workshop - June 6, 2024: 1:00 PM 4:00 PM : Reserved for further discussions if needed and Q&A session. - Based on the feedback from these workshops, ERCOT will finalize ICCP/Market Interface design specifications and publish draft versions to the ERCOT website. - This engagement will help QSEs and their vendors start planning their RTC+B systems design and implementation early to align with ERCOT s RTC+B project implementation timelines which is critical for ERCOT to deliver this project successfully and on time. - Discussions and artifacts will be highlighted and shared at regular RTCBTF meetings. - Questions? 10 Public
