Description: This Nodal Protocol Revision Request (NPRR) provides a process to allow for the use of actual metered interval data for initial settlement of an Operating Day for Electric Service Identifiers (ESI IDs) that currently require BUSIDRRQ Load Profiles. Currently, meter data is sent monthly on the 867_03 for ESI IDs with BUSIDRRQ Load Profiles, so most of the data used for initial settlement for these ESI IDs is estimated using proxy day data. The ESI IDs are resettled with actual data during final Settlement on the 55th day following the Operating Day. The result is inaccurate initial Settlement.
Reason: Market efficiencies or enhancements
