NPRR285  Generation Resource Base Point Deviation Charge Corrections

This Nodal Protocol Revision Request (NPRR) provides that an exception to the Generation Resource Base Point Deviation Charge for any 15-minute Settlement Interval which includes a Security-Constrained Economic Dispatch (SCED) interval that is less than four minutes in duration. Additional changes are proposed to Base Point Deviation Charges for over- and under-generation, to be effective upon system implementation. This NPRR also removes the Base Point Deviation Charge for all Intermittent Renewable Resources (IRRs) until corrections to the Nodal systems can be implemented so that the charge applies to IRRs only when there is clear indication that the Base Point received needs to be followed. A flag will be sent by ERCOT to the Qualified Scheduling Entity (QSE) for each Resource indicating SCED has Dispatched a Generation Resource below the High Dispatch Limit (HDL) used by SCED. This flag will be used by the Settlement system to determine when the IRR Generation Resource Base Point Deviation Charge will apply. In addition, the calculations are changed to apply the charge whether the Settlement Point Price is negative or positive.
