ERCOT Market Trials and Credit Requirements

  • Indications from different market participants that credit requirements have improved significantly, with improved data, but that credit requirements remain extremely high

    • This applies to both the energy markets and CRR markets

    • Note NPRR 206 has now been been incorporated into the credit requirements, and the ‘e’ factors are expected to be incorporated on or about August 9th

  • Other issues identified

    • Availability to reports, and accuracy ~much improved, but issues are still being worked on by Staff

    • Clarity on how cutover will work ~Staff is developing a plan to use nodal prices for Day 1

    • Parallel review of credit requirements has begun (next slide)

        • MCWG will continue to monitor and discuss again in late August at the next face-to-face meeting


Luminant crr proposals 1

Luminant CRR Proposals (1)

Prior to Nodal Inception

Revise variable inputs within the Auction Clearing Price Exposure (“ACPE”) calculations and manage FMM Weights

Decrease “Y” and “A” from $1.5 to a “Rightsized” value

Eliminate the need for a negative bid to post collateral (i.e. remove absolute bid price requirement)

Revise the FMM weights following an auction to reflect 100% ACP and monitor


Luminant crr proposals 2

Luminant CRR Proposals (2)

Other Parking Desk Proposals for CRR’s

Incorporate partial netting of CRRs into TPE, DAM & DALE

Increase ACL utilization limit from 90%

Revise FCEOBL to equal the Sum of ACPEOBL and - FMMOBL

Bid Auction constraint based on the Shadow Price or a Historical Auction/Market Value

Determine ACPE values based on Source/Sink, Volatility, TOU, Term, CPTY

Design FCE equations to incorporate FWD market values

Incorporate CRR Account Balance into the TPE equation

Exclude Counterparties who have granted a first lien from the Auction Exposure Calculation and from prepayment requirements

First Priority Security Interest (CRR’s)

    • Appears Munis can not sign

    • Others indicated they may be prohibited under their financing agreements, though this was not uniform

    • Stakeholders were encouraged to submit comments that may allow them to sign

      • Will revisit after ERCOT reviews the first set of comments

      • Stakeholders may need to seek waivers from lenders, or in the case of Muni’s a Protocol change, to allow for netting

  • Staff to review language to ensure language is consistent with intent, and modify accordingly.
