LONG DESCRIPTION:  On July 1, 2012, ERCOT will unbox the remaining grey-boxed portion of Nodal Protocol Revision Request (NPRR) 379, EILS Dispatch Sequence and Performance Criteria Upgrades, which was approved by the ERCOT Board on September 20, 2011. This unboxing of NPRR379 will activate Protocol Section 3.14.3.1(2), which requires that "ERS offers shall be submitted only by QSEs capable of receiving both Extensible Markup Language (XML) messaging and Verbal Dispatch Instructions (VDIs) on behalf of represented ERS Resources", and Protocol Section 6.5.9.4.2(2)(a)(iii), which requires that "ERCOT shall deploy ERS via an XML message followed by a VDI to the all-QSE Hotline."
Along with the unboxing of NPRR379, ERCOT will unbox the remaining grey-boxed portion of the related Nodal Operating Guide Revision Request (NOGRR) 077, Synchronization with NPRR379, EILS Dispatch Sequence and Performance Criteria Upgrades, which was approved by the Technical Advisory Committee (TAC) on October 6, 2011. This unboxing of NOGRR077 will activate Nodal Operating Guide Section 4.5.3.3(2)(a)(iii), which requires that "ERCOT shall deploy ERS via an XML message followed by a VDI to the all-QSE Hotline."
ADDITIONAL INFORMATION:  Pursuant to Protocol Section 21.6, Nodal Protocol Revision Implementation, and Nodal Operating Guide Section 1.3.6, Nodal Operating Guide Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
