This Nodal Protocol Revision Request (NPRR) corrects the formula for the calculation of the Load-Allocated Monthly BLT Amount per QSE (LAMBLTAMT) in paragraph (3)(c) of Section 6.6.3.5 to reflect a charge, rather than a payment, to comport with the facial intent of NPRR553, Monthly BLT Payment and Charge for Presidio Exception, and with the system implementation of that charge. The title of NPRR553 references a charge (in addition to a payment) and the language preceding the formula expresses an intention to impose a charge. For these reasons, ERCOT believes that the omission of the required “-1” at the beginning of the formula was inadvertent and should be corrected.
