Sections:	16.2.7.4, 16.2.8, 16.2.9, 16.2.9.1, 16.2.9.1.1, 16.2.9.1.2, 6.2.9.1.3, 16.2.9.1.4,
Description:	Several changes are proposed, with the three primary changes being: (1) Change the formula for Net Load Imbalance Liability and Net Resource Imbalance Liability (NLRI) to better match with Nodal formula ā?? perform calculation on a more detailed level using entity specific pricing rather than WA_MCPE pricing (2) Require/allow ERCOT to withhold payment from entities that have exceeded their EAL or NLRI. (3) Address request by RMS/Texas Set to add requirement that QSEs (that are LSEs) and are in Payment Default to provide ESID information on their customers.
Reason:	1) Changes are proposed to make the NLRI calculation more consistent with the Nodal formula. 2) and 3) Changes are proposed to strengthen ERCOTā??s position by holding payments, if needed and by obtaining customer information more timely, if needed.
