NOTICE DATE:  November 24, 2008

NOTICE TYPE:  M-A112408-01 Settlements

SHORT DESCRIPTION:  LPGRR031, Profile Decision Tree Changes for Distributed Renewable Generation (DRG)

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  January 1, 2009

LONG DESCRIPTION:  On November 17, 2008, the ERCOT Board of Directors approved Load Profiling Guide Revision Request (LPGRR) 031, Profile Decision Tree Changes for Distributed Renewable Generation.  The most significant change associated with LPGRR031 is that ‘IDRRG’ will not be included in the Profile Decision Tree as a valid profile segment on January 1, 2009. 

LPGRR030 specified IDRRG as a valid profile segment, and subsequent to its approval, the procedure for DRG ESI IDs with an IDR is to obtain a Resource ID.  Consequently, IDRRG is no longer needed as a profile segment.

The profile types for which load profiles will not be published or used in settlement are:

RESIDRRG

BUSIDRRG

Additionally, a revised Profile Decision Tree (Appendix D) has been posted with the Load Profiling Guide, and has an effective date of January 1, 2009.

ACTION REQUIRED:  Market Participants whose systems contain the RESIDRRG or BUSIDRRG profile types must ensure their systems will not be adversely affected by non-assignment of these profile types.

ADDITIONAL INFORMATION:  Additional information can be obtained from the Load Profiling Guide website at: http://www.ercot.com/mktrules/guides/loadprofiling/index.html
