Description: This Nodal Protocol Revision Request (NPRR) corrects language within NPRR400, Eliminate Unsecured Credit for CRR Auctions and for Future Credit Exposure and Eliminate Netting of FCE with CCE, which was approved by the ERCOT Board on October 18, 2011. Modifications include the following: · Available credit limits for the CRR Auction (ACLC) and Available Limit for the DAM (ACLD) must be positive values; · Brackets in Minimum Collateral Exposure (MCE) calculation corrected; and · Ensure that collateral requests to cover non-CRR exposures are not overstated because of potential negative Remainder Collateral values.
Reason: To correct current Protocol language implemented by NPRR400.
