NPRR #355 · Revision Request
NPRR355 Adjust the Calculation of the Real-Time Settlement Point Price for a Load Zone
ReasonThe two equations using the RTSPP and RTSPPEW prices are the Real-Time Energy Imbalance Amount (RTEIAMT) at a Load Zone and Block Load Transfer Resource Amount (BLTRAMT). The proposed adjustments will ensure that for 15 minute Settlement Intervals in which there is no congestion (i.e. within each SCED interval all the LMPs are the same at all electrical buses) there will be no difference in the Load Zone, Resource Node and Hub 15 minute prices.

Summary
This Nodal Protocol Revision Request (NPRR) removes the energy-weighting in the current calculation for the Real-Time Settlement Point Price (RTSPP) for a Load Zone. It also adds a new RTSPP for a Load Zone that is energy-weighted (Real-Time Settlement Point Price Energy-Weighted (RTSPPEW)) and adjusts the appropriate formulas that use these prices. This NPRR also corrects the Real-Time Price for the Energy Metered for each Resource meter at bus (RTRMPR b) in the event that the Energy at bus near Real-Time (EBNRT) is less than or equal to zero. This NPRR also includes several minor, non-substantive corrections.
