▶️ 7 - Confirmation of 2025 Subcommittee/Sub Group Leadership -Vote- TAC Chair
New leadership appointments include Sandeep Borkar from LTRA to vice chair ROS, Blake Holt from LTRA to chair WMS, and Jett Price from Golden Spread to chair the credit finance subgroup.
The CFSG has been discussing changes to the EAL credit equation for about 2 years, proposing a simpler adjustment rather than a complete rewrite.
The proposal is expected to be submitted soon, with the final language reviewed by the CFSG for completeness.
The EAL formula focuses on capturing real-time and DAM settlements, addressing overcollateralization during price spikes.
The proposed changes aim to reduce both overcollateralization and undercollateralization, ensuring efficiency without worsening other issues.
The tweak involves changing how the forward adjustment factor is applied to historical invoices.
The ERCOT collateral requirements sometimes spike unnecessarily based on the current formula, leading to inefficiencies.
The proposal aligns historical and forward-looking invoices more directly, helping to prevent double spikes like those seen in events such as winter storm Elliott.
Some expressed concerns about potential undercollateralization but acknowledged the proposal improves these instances.
The change is seen as correcting inefficiencies without compromising market participant security.
There is an understanding that while this improves the current system, additional future adjustments may be required.
Stakeholders support the proposal for its prudent approach toward resolving identified issues efficiently.
Implementation of the changes is expected within about a year, seen as a lightweight alteration manageable by ERCOT amidst current projects.

▶️ 12.01 - NPRR1190, High Dispatch Limit Override Provision for Increased Load Serving Entity Costs
The NPRR1190 item is currently tabled at ERCOT, with discussion ongoing at WMS and WMWG. Update given by Blake Holt.
A compromise solution has been proposed that includes a review and potential modification of the protocol if excessive costs arise from the eligibility expansion on HDL override payments.
The current feedback is generally positive, with vocal parties supporting the compromise, but consumers require more time to review the language.
