Description: This Nodal Protocol Revision Request (NPRR): (1) revises the Real-Time Energy Imbalance equations to determine intermediate data elements for the Resource’s share of the generation site total revenues; (2) revises the Resource Node, Load Zone, and Hub Real-Time Energy Imbalance equations to determine volumetric imbalance for each Qualified Scheduling Entity (QSE) and Settlement Point; and (3) revises the Reliability Must-Run (RMR) Adjustment Charge to charge the QSE for the revenues paid in accordance with the energy imbalance calculation.
Reason: This NPRR will provide market volumetric imbalance calculations and will achieve revenue neutrality for QSEs with RMR Units.
