NOTICE DATE: May 17, 2021
NOTICE TYPE: M-A051721-01 NPRR
SHORT DESCRIPTION: Implementation Details of NPRR1051
INTENDED AUDIENCE: All Market Participants
DAYS AFFECTED: May 29, 2021
LONG DESCRIPTION: On May 29, 2021, Protocol language associated with Nodal Protocol Revision Request (NPRR) 1051, Removal of the Price Floor Applied to Day-Ahead Settlement Point Prices, will be implemented.
NPRR1051 removes the administrative price floor applied to Day-Ahead Market (DAM) Settlement Point Prices. This change removes the potential for price differences between the DAM optimization clearing price and the DAM Settlement price for Point-to-Point (PTP) Obligation bids that could be caused by application of the administrative price floor. Such price differences could create post-DAM award inconsistencies between the PTP Obligation bid price and the Settlement price. NPRR1051 does not impact the Real-Time Market (RTM) administrative price floor.
ADDITIONAL INFORMATION: Pursuant to Nodal Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
NPRR1051 and associated documents can be found on the ERCOT website.
