NPRR683  Revision to Available Credit Limit Calculation

Approved sponsor Luminant posted 2015-02-09 ercot.com
ReasonThe current method unfairly penalizes Counter-Parties posting excess collateral and equally incents other Counter-Parties to post little to no excess collateral. The method proposed by this NPRR better aligns collateral requirements with actual credit risk and provides a level playing field for all Market Participants.

Summary
This Nodal Protocol Revision Request (NPRR) revises the calculation of Available Credit Limit for the CRR Auction (ACLC) and Available Credit Limit for the DAM (ACLD) by replacing the existing 10% discount to the ACL based on the Counter-Party’s unused letter of credit amount with a 10% gross up of the sum of the Total Potential Exposure Any (TPEA) and the Total Potential Exposure Secured (TPES).
