This Nodal Protocol Revision Request (NPRR) modifies the Nodal Implementation Surcharge (NIS) calculation to mirror the existing zonal calculation, by including generation from Non-Modeled Generators and energy imported into the ERCOT System during a declared Emergency Condition through each Direct Current Tie (DC Tie) in response to an ERCOT Dispatch Instruction.
Reason:
The reason for this NPRR is to correct an oversight in the calculation of NIS in the Nodal market which currently does not include generation from Non-Modeled Generators or emergency DC Tie imports. This change synchronizes the Nodal Protocol Settlement of NIS with the zonal Protocol Settlement of NIS.
