SHORT DESCRIPTION: NPRR322 WebEx workshop

INTENDED AUDIENCE: ERCOT Market Participants

DAY AFFECTED: November 27, 2012

LONG DESCRIPTION: On December 6, 2012, ERCOT will complete the implementation of Nodal Protocol Revision Request (NPRR) 322, Real-Time PTP Option Modeling, which was approved by the ERCOT Board on June 21, 2011.

Because there are a number of market-facing changes to the Market Manager, reports, and settlements as a result of NPRR322, ERCOT will host a WebEx workshop detailing the implementation. The primary audience is Qualified Scheduling Entities (QSEs) representing Non-Opt-In Entities, as that is the main audience affected, but anyone is welcome to join. The WebEx workshop will be held on November 27, 2012, 14:00 – 15:30 CPT. Details can be found on the ERCOT calendar page at http://www.ercot.com/calendar/2012/11/20121127-NPRR322.
