Load Profiling
Guide Revision Request (LPGRR) 026 submitted on July 31, 2007, proposed changing
the ERCOT production system to generate and publish Load Profiles with three
digits to the right of the decimal point for the following Load Profile
Types:
BUSNODEM
RESHIWR
RESLOWR
On December 11,
2007, the ERCOT Board approved LPGRR026.
The applicable
backcasted Load Profiles will contain the three digits to the right of the
decimal point beginning with the backcasts for Trade Date August 1, 2008, which
will be published on August 2, 2008.
The applicable
forecasted Load Profiles will contain the three digits to the right of the
decimal point beginning August 1, 2008.
The corresponding
Load Profile Model spreadsheets (v2.2) are part of the Load Profiling Guide and
are posted at http://www.ercot.com/mktrules/guides/loadprofiling/current.html, under Load Profiling Guide Appendix E (Effective upon system
implementation).
ACTION
REQUIRED: Market
Participants may need to take steps to ensure that their replication of the
ERCOT Load Profile Models (i.e., BUSNODEM, RESHIWR, and RESLOWR) round the final
15-minute interval values to three digits to the right of the decimal
point. Those who reference Load
Profiling Guide Appendix E: Profile Model Spreadsheets need to download the
latest version from http://www.ercot.com/mktrules/guides/loadprofiling/current.html.
