Description: This Nodal Protocol Revision Request (NPRR) clarifies the collateral requirements for Congestion Revenue Right (CRR) Account Holders and Counter-Parties who participate in the CRR market. The change will correct certain formula issues in the ERCOT Board-approved NPRR357, Revisions to Collateral Requirements Concerning CRR Auctions, that result in the overcollateralization of CRR Account Holders and Counter-Parties. Further, the specific equations are removed as they more appropriately belong in a white paper that has been created by the ERCOT CRR team in parallel with this NPRR in the same manner as was done for Day-Ahead Market (DAM) credit. With this correction to the Protocols, the CRR credit screening will be consistent with the treatment of the DAM credit exposure equations.
Reason: The collateral requirements for CRR Account Holders and Counter-Parties to participate in the CRR market based on NPRR357 are greater than what is actually needed in the market but ERCOT believes this was not the intent. Thus, Market Participants have an increased cost of credit. This NPRR, in conjunction with the related white paper addresses the overcollateralization of CRR Account Holders and Counter-Parties and better reflect the risks and costs of participation in the CRR market.
