Grid Monitor AI | Posted 05/19/2025

▶️1 - Antitrust Admonition
▶️2 - Revisions to Credit Exposure Calculations for Ancillary Service Products related to Real-Time Co-Optimization (RTC)
02.-Credit-Updates-for-RTC-v2.pdf
- Updated slides were posted this morning with red boxes indicating report changes.
- The presentation focused on changes related to credit with the RTC project.
- Unbilled Day-Ahead Amounts (UDAA) now includes virtual offers activity for ancillary services.
- Current AS activity is captured in AS payments and charges; virtual offers will be added.
- Protocol changes were listed for inclusion in reports.
- Two components of EAL calculations, real-time liability completed not settled and real-time liability forward, will include AS payments and charges.
- Addition of two new columns in reports for volumes and amounts.
- Minimum Current Exposure (MCE) calculations will capture day-ahead spread between day-ahead and real-time market prices.
- Two new columns added to MCE for extrapolated volume and amounts.
- Default Uplift supporting data reporting will capture uplift volumes in data report, with sections for initials, finals, and true ups.
- The presentation was part of implementation of RTC+B, involving minimal changes to existing infrastructure.
▶️3 - DC Energy proposal on CRR collateralization
03.-CRR-Credit-Proposal-DC-Energy.pdf
- The item discusses areas of potential exploration instead of a formal proposal regarding CRR collateral.
- CRR collateral has not been reviewed in about five years, prompting a timely exploration.
- Topics include potential improvements in collateral efficiency and accuracy.
- ERCOT might provide a high-level overview of current CRR collateral rules in future meetings.
- Two main ideas were discussed: interactions between obligations and options, and monthly collateral calculation approach.
- Current rules calculate collateral for obligations and options separately, ignoring portfolio interactions.
- Current method calculates each month in isolation, leading to potential over-collateralization.
- Recommendation includes considering a single Portfolio Weighted Adder (PWA) where obligations and options are considered together.
- Another suggestion is to adjust the correlation assumption between monthly outcomes from 100% to possibly 50%, similar to PJM's methodology.
- A gap analysis is proposed to assess the adequacy of current collateral requirements.
- Discussion on collateralization is open for further exploration and analysis, potentially leading to a comprehensive review.
- Some participants express support for revisiting the collateral framework given potential inefficiencies.
- There might be wider market implications and benefits in terms of freeing up capital and improving market processes.
- Consensus for more active participation and continued discussion to address CRR collateralization.
- Possible revisit of a previous proposal on default uplift allocation connected to collateral discussions.
▶️4 - Stress Testing Framework
04.-Stress-testing-framework.pdf
- Introduction of a new stress testing framework project linked but distinct from previous NPRR1067 proposal.
- The framework aims to proactively identify and manage credit risks related to operational and market decisions.
- Discussion around the impact of extreme events, like Winter Storm Uri, on market participants and overall market stability.
- ERCOT's current credit framework lacks unsecured credit and minimum capitalization requirements; the new approach aims to proactively manage risks.
- The proposed framework will involve identifying, measuring, and mitigating risks before events occur.
- The goal is to develop a proactive risk management framework for potential default scenarios under various stress events.
- Framework will focus on triggering conversations with potential high-risk entities to raise awareness.
- Concerns were raised about the feasibility and effectiveness of the approach in preventing defaults like those experienced during Winter Storm Uri.
- Participants emphasized the need for awareness and risk assessment rather than a reactive approach, highlighting existing market uplift mechanisms for defaults.
- The new approach will concentrate initially on load and load-gen entities to assess and manage risk effectively.
- Discussion of using basic, intuitive methods to create early awareness without complex modeling.
- Clarification that ERCOT is not seeking to implement margin calls based on these stress tests.
- Consensus on the necessity to start the stress test framework development and refine it over time.
- Engagement with other ISOs and credit rating agencies to understand and incorporate their insights.
- Discussion around how the framework will help identify potential risk entities but won't seek additional collateral based on stress testing outcomes.
- Feedback and engagement with market participants are deemed crucial for the development and refinement of the framework.
▶️5 - Standard Review of NPRRs for Credit Impacts (Vote)


- Motion to approve the combo ballot as presented passed unanimously with no abstentions.
- Three NPRRs were discussed today: NPRR1282, NPRR1281, and NPRR1277.
- NPRR1282 involves changes to ancillary service duration for real-time co-optimization, focusing on operational process improvements.
- NPRR1281 aims to improve the designation of alternate FFSS resources by clarifying early equivalent availability factor language, also focusing on operational improvements.
- NPRR1277 involves revisions to the EAL formula, addressing over-collateralization while reducing instances of under-collateralization, with positive credit implications.
- No revisions were filed for NPRR1277; it was accepted as submitted.
- Combo ballot created for voting on these NPRRs.
- All representatives voted in favor, and the motion carried successfully.
▶️6 - ERCOT Updates
▶️6.1 - Credit Exposure
06.-ERCOT-Updates-Credit-Exposure-May-2025.pdf
- Market wide Total Potential Exposure (TPE) decreased from $1.84 billion to $1.78 billion in April due to extrapolated exposure rolling off.
- Discretionary credit exposure decreased by 9% from $4.1 billion to $3.73 billion.
- No unusual collateral activity noted for April.
- TPE for April is less than $2 billion, down to $1.7 billion.
- RTSPP and DASPP prices for April mostly under $50, except April 7 with prices around $140 and $40 respectively.
- Total credit limit for April is about $506 million with major collateral instruments such as actuality bonds, letters of credit, and cash.
- LC concentration among banks is within concentration limits.
- Highest market segment exposure is for load and gen, followed by traders, load, generation, and serial activity.
- Invoice exposures for all market segments are within TPE coverage.
- Invited questions and thanked participants.
