NPRR326 Adjust the Calculation of the Real-Time Settlement Point Price for a Resource Node

Approved sponsor ERCOT posted 2011-02-10 ercot.com

ReasonThe current method of calculating payments and charges of Point-to-Point (PTP) Obligations and PTP Options settled in Real-Time based on Base Point weighted Real-Time Settlement Point Prices can lead to payments and charges when there is no congestion, which are not supported by congestion rent and can lead to Real-Time Revenue Neutrality Allocation uplift. With the implementation of this NPRR, payments and charges for PTP Obligations and PTP Options settled in Real-Time will be more accurate and should only occur when there is Real-Time congestion.
