NOTICE TYPE: M-A042219-01 NPRR
SHORT DESCRIPTION: Implementation details of NPRR877 (Phase 1)
INTENDED AUDIENCE: All Market Participants
DAY AFFECTED: May 1, 2019
LONG DESCRIPTION: On May 1, 2019, Protocol language related to Phase 1 of Nodal Protocol Revision Request (NPRR) 877, Use of Actual Interval Data for IDR ESI IDs for initial Settlement, will be implemented.
This 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.
ADDITIONAL INFORMATION: Pursuant to Nodal Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is to provide notice as soon as practicable, but no later than 10 days prior to implementation.
NPRR877 and associated documents can be found on the ERCOT website.
