RTC+B Program Update (excerpt from April Board T&S RTC Update) 3 Public
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 Each activity will have a public-facing Scorecard and exit Criteria 3-4 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 SCED/LFC (QSE RTC offers and telemetry to support closed-loop frequency control test 2-3 tests of 2-4 hour durations) Transition to Go-Live Upon completion of testing, confirmation of ERCOT and market readiness for Go-Live. QSE Telemetry Tests (Individual QSE to follow UDSP and support new ramp rate and ESR telemetry) RTC QSE Telemetry Check-out (QSEs add/verify new telemetry points for UDSP, New ramp rates, ESR telemetry) Day-Ahead Market (Non-binding DAM using QSE offers for at least 2 tests) Current draft of the earliest possible dates for Market Trials and Go- Live that have been shared through TWG and the RTC+B Workshops, in support of Market Participants readiness at RTCBTF. Actual Market Trials and Go-Live milestones are to be determined and will be communicated no later than 9/30/24. 1-2 months 4 Updated 2024-05-22 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

Upcoming RTC+B Clarification NPRRs RTC+B NPRR next steps: RUC Capacity Short NPRR1236 is going to July PRS Meeting Verifiable Cost Hydro MOC will be part of clarifying NPRR ERCOT is developing at least 2 clarifying NPRRs with target of July drafts: Clarification NPRR after completing business requirements (eg, drift in baseline since 2019, discrepancies and/or small gaps found during business requirement development) Clarification NPRR as an extension of NPRR1014 Single Model to clarify single model language in other areas of protocols. Note- All changes are intended to be as designed clarifications, aligned with Key Principles, and have no system impacts. Current plan is to share initial drafts with RTCBTF, and then ERCOT will formally file as NPRRs to allow vetting of comments via existing PRS/TAC process and supported by RTCBTF to thoroughly review. 7 Public
Reviewed at June RTCBTF - Issue 3 - Framework for periodic analysis comparing RTC and the current ORDC design - ERCOT updated the publicly available RTC Excel tool and will be posted to RTCBTF home page - Next RTCBTF meeting lay out date estimates for development of tool capabilities. - Issue 20 - Review of the Energy and AS Offer Caps in the context of Current Policy - Review last month s presentation and see if any questions (none) - Issue 9-10 - Market Readiness and Technical Workshops - Reviewed outline of market trials sequence and objectives (seeking Market Feedback) - Reviewed telemetry changes shared at RTC+B Technical Workshops - Asked MPs what is needed to continue to develop their changes. - Issue 18 - Review of the AS Demand Curves in the context of current policy - ERCOT Operations provided feedback on questions from prior RTCBTF meetings 8 Public
RTCBTF Next steps - Wrapped 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 by end of June. - 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. - July 17th - Next RTCBTF - Feedback on Market Trials Plan from MPs and review of QSE Attestation - Questions? 9 Public
