NOTICE DATE:  November 18, 2011
NOTICE TYPE:  M-A111811-01 NPRR
SHORT DESCRIPTION:  Implementation details for NPRR338
INTENDED AUDIENCE:  QSE and CRRAH settlement personnel
DAY AFFECTED:  December 1, 2011
LONG DESCRIPTION:  On December 1, 2011, ERCOT will unbox the grey-boxed language for Nodal Protocol Revision Request (NPRR) 338, Modifications to Support Revenue Neutrality, which was approved by the ERCOT Board on July 19, 2011.
The grey-boxed language in Protocol Section 9.2.5, DAM Resettlement Statement, allows ERCOT to resettle the Day-Ahead Market (DAM) in the event that a DAM Settlement error, which does not otherwise meet the Protocol requirements for resettlement, will impact ERCOT's ability to achieve revenue neutrality.
The grey-boxed language in Protocol Section 9.19, Partial Payments by Invoice Recipients, deducts the amount collected for the shortfall charges for Congestion Revenue Right (CRR) Owners from the amount received on all Real-Time Market (RTM) Invoices prior to prorating the payout to the RTM Invoice Recipients.
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.
NPRR338 and associated documents can be found on the ERCOT website, under Market Rules, at http://www.ercot.com/mktrules/issues/nprr/326-350/338/index.
