Missing reports observed, specifically forecast reports, possibly due to holidays.
Request made to notify the WMWG Exploder when reports are posted.
Ryan King committed to following up internally to locate missing reports and update the group.

A question was raised about the AS provision and performance state of charge report.
Unrecognized new material was noticed in the report.
Uncertainty existed about having the correct ERCOT SMEs available to explain the content.
Slide 3 and 4 were identified as needing further explanation.
Ryan King was tasked with following up with Luis and his team for a response.
There was no urgency for the item; it was suggested to revisit the discussion in February.
The aim was to understand a trend that ERCOT might be highlighting better.

Discussion on the testing and qualification of battery capacity for constraint management within the MRA documentation.
Explanation provided on the process of testing batteries as MRAs, similar to the testing of batteries for ancillary services.
Clarification sought on the standard duration requirements for testing battery capacity in RFPs.
Further inquiries about the process ERCOT uses to determine the duration requirements for RMR units.
Confirmation that the RFP documents outline the specific duration and capacity requirements for different technologies.
Recognition of a need for additional NPRR language to specify capacity value calculations for ESRs, including state of charge requirements.
Discussion on the implications of ESRs not having enough state of charge during standby periods.
Decision to table NPRR1256 for further clarifications and additional language to address capacity payment concerns.

Discussion delayed due to timing of the meeting immediately after holidays.
Bill Barnes has not had the opportunity to gather feedback from concerned parties such as Eric Goff.
Suggestion to postpone further discussion for another month to allow for comprehensive feedback and amendments.
Plan to have a more meaningful discussion in February after additional outreach.
No further comments heard from other participants, supporting the delay.

Lucas Turner worked with ERCOT to clarify and revise the language of NPRR1229 to ensure ease of implementation if approved.
Key changes include renaming to 'cost recovery payment' and updates for readability and specificity.
Settlement formulas, titles, and conditions required for payment were clarified and restructured.
Major changes included removing the 'real-time market opportunity costs' from the considerations and capping compensation components.
ERCOT's plan includes three main cost components: recovery for bilateral contract costs, unit damage compensation, and startup payments.
Manual calculation of payments will be used until system changes are implemented.
Debate occurred over the use of High Sustained Limit (HSL) versus break-point in payments calculation; concerns of potential overcompensation were discussed.
Startup payment logic might not align with other compensation formulas; further alignment might be needed.
No consensus was reached on using shared caps between NPRR1229 and NPRR1190; more discussions expected.
Some additional clarifications by ERCOT are pending for the language of NPRR1229, but they won't impact the main policy components.
It was decided to postpone further discussion on NPRR1229 until after related conversations on NPRR1190 develop further next month.

The analysis needed for the NPRR discussion was delayed due to holidays but is expected by the February meeting.
Katie Rich requested clarification on TCOS congestion costs and trends over 10 years, and CARD and congestion costs paid by load by zone.
Austin Rosel mentioned they might be ready with the analysis by January 30th meeting and took note of some requested analyses.
Discussion around historical data focused on using a recent 12-month period with suggestions to explore longer timeframes.
Data breakdown by load class (residential, commercial, industrial) was suggested and may be included as an appendix.
There was confusion and clarification requested on the distinction between congestion costs and congestion rent.
Steve provided a potential method to compare load zone prices to system Lambda to determine actual congestion costs.
The feasibility of completing the expanded analysis by January 30th was uncertain due to new analysis requests.
Steve suggested including historical years with significant price fluctuations in the West load zone.
Bob Whitmire noted upcoming changes with NPRR1188 affecting nodal pricing for loads.

Discussion on scheduling 2025 meetings a few days before the next WMS to address coordination issues.
Request for feedback on meeting timing and openness to adjusting schedules.
Update on 2025 WMWG leadership nominations: Amanda Frazier for chair and Trevor Safko for vice-chair. No other nominations received.
Introduction of Sam Fabricant to address questions regarding the State of Charge report.
Explanation of slides related to ESR performance, unit trips, and evaluation of RRS provisioning.
Clarification on a slide focusing on ESR performance in meeting set points for both GREDP and CLREDP sides.
No changes noted in report data since initial findings in August.
Open invitation for any further questions or issues to be addressed.
