NOTICE DATE:  March 24, 2011
NOTICE TYPE:  M-A032411-01 NPRR
SHORT DESCRIPTION:  Implementation details of NPRR303
INTENDED AUDIENCE:  ERCOT Market Participants
DAY AFFECTED:  April 1, 2011

LONG DESCRIPTION:  On March 22, 2011, the ERCOT Board approved Nodal Protocol Revision Request (NPRR) 303, Requirement to Post Point to Point (PTP) Options Cleared in DAM or Taken to Real-Time. Until the full implementation of reporting requirements is delivered in May 2011 (the target implementation date), ERCOT will continue to manually post the report that currently supports NPRR293, Requirement to Post PTP Obligation Quantities Awarded in DAM, and add the required data from NPRR303 from the Day-Ahead Market (DAM) solution.

As a result of this NPRR, beginning on April 1, 2011, the existing DAM Total PTP Obligation Bid Awards by Settlement Point report will have two new columns of data added. The new structure of this report is:

*         DELIVERYDATE

*         HOURENDING

*         STL_PNT

*         TOTAL_PTP_OBL_AWARDED_SOURCE

*         TOTAL_PTP_OBL_AWARDED_SINK

*         TOTAL_CRR_NONDAMAWARDED_SOURCE (new column)

 *   TOTAL_CRR_NONDAMAWARDED_SINK (new column).
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. Ten days notice was not possible in this case due to the timing of the Board approval and the necessary implementation date.
The DAM Total PTP Obligation Bid Awards by Settlement Point report is located on the Market Information System (MIS) under Day-Ahead Market Results at https://mis.ercot.com/pps/tibco/mis. An ERCOT digital certificate is required to access the MIS.
The report is also located on ERCOT.com under Day-Ahead Market Results Reports at http://www.ercot.com/mktinfo/dam/.
NPRR303 and associated documents can be found on the ERCOT website, under Market Rules, at http://www.ercot.com/mktrules/issues/nprr/301-325/303/index.
