NOTICE DATE: September 15, 2011 NOTICE TYPE: M-B091511-01 NPRR SHORT DESCRIPTION: Implementation details of NPRR346 INTENDED AUDIENCE: ERCOT Market Participants DAY AFFECTED: September 27, 2011 LONG DESCRIPTION: On September 27, 2011, ERCOT will implement Nodal Protocol Revision Request (NPRR) 346, Removal of Redundant Posting Requirements Related to Electrical Bus Changes, which was approved by the ERCOT Board on July 19, 2011. NPRR346 removes a redundant posting requirement from Protocol Section 3.5.1, Process for Defining Hubs, because similar information is already being posted per Protocol Section 3.5.3.1, Posting of Hub Buses and Electrical Buses included in Hubs. ADDITIONAL INFORMATION: Pursuant to 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. NPRR346 and associated documents can be found on the ERCOT website, under Market Rules, at http://www.ercot.com/mktrules/issues/nprr/326-350/346/index.
