Summary
This Nodal Protocol Revision Request (NPRR) revises paragraph (2) of Section 6.6.1.5, Hub LMPs, to apply the Hub Locational Marginal Price (LMP) formulas to the Panhandle 345 kV Hub and the Lower Rio Grande Valley 138/345 kV Hub. In the case of the Lower Rio Grande Valley 138/345 kV Hub, this proposed change would only apply after implementation of NPRR941, Create a Lower Rio Grande Valley Hub. The proposed revisions also eliminate the portions of Hub Real-Time Settlement Point Prices (SPPs) formulas that are designed to address the condition of all Hub Buses within a Hub being de-energized. The SPP logic is redundant with what occurs in the calculation of LMPs and the formulas are unclear regarding how to manage the case in which all the Hub Buses are de-energized for only a portion of a 15-minute Settlement Interval.
