SHORT DESCRIPTION:  Implementation details of NPRR672

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  June 1, 2015

LONG DESCRIPTION:  On June 1, 2015, ERCOT will implement Nodal Protocol Revision Request (NPRR) 672, Clarification of EMR and ONEMR Status, which was approved by the ERCOT Board on April 14, 2015. 

This NPRR clarifies the conditions whereby a Resource may utilize the ONEMR or EMR Current Operating Plan (COP) status. The ONEMR and EMR statuses restrict the systems from sending Reliability Unit Commitment (RUC) or Security-Constrained Economic Dispatch (SCED) instructions to Resources. This NPRR clarifies conditions that allow either of these status values to be used.

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.   

NPRR672 and associated documents can be found on the ERCOT website.
