NOTICE DATE:  December 3, 2012
NOTICE TYPE:  M-B120312-01 NPRR
SHORT DESCRIPTION:  Implementation details for NPRR397 and WebEx workshop
INTENDED AUDIENCE:  QSEs with Resources
DAYS AFFECTED:  December 12, 2012, and January 7, 2013
LONG DESCRIPTION:  On January 7, 2013, ERCOT will begin executing reconfiguration Supplemental Ancillary Services Markets (SASMs) with the implementation of Nodal Protocol Revision Request (NPRR) 397, Balance of the Day Ancillary Service Market, which was approved by the ERCOT Board on April 17, 2012.
NPRR397 allows the SASM to be operated as a balance of the day market for Ancillary Services. This will allow Qualified Scheduling Entities (QSEs) the opportunity to change their Ancillary Service Supply Responsibility for the remainder of the current Operating Day through a reconfiguration SASM, which will be executed at 09:00 CPT daily.

Because of the coordination required between ERCOT and QSEs, ERCOT will host a WebEx workshop to review and discuss the timelines and expectations introduced by NPRR397 to help ensure a smooth transition. The primary audience is QSEs with Resources that provide Ancillary Services. This workshop will be held on December 12, 2012, from 14:00 - 16:00 CPT. Additional details and material will be posted on the ERCOT calendar page at http://www.ercot.com/calendar/2012/12/20121212-OTHER.
