The variables in question are used by ERCOT in the generation of forecasted and backcasted Load Profiles. This change also deletes the BUSIDRRG and RESIDRRG profile model spreadsheets, which were approved but never implemented due to changes in how Profile IDs are assigned for sites that have Advanced Metering.||06/24/2009||Ernie Podraza on behalf of the Profiling Working Group (PWG)||No||Appendix E: Profile Model Spreadsheets||Approved|
|LPGRR035||Addition of Time Of Use Schedules (TOUS) to Profiles with Interval Data Recorder (IDR) Meter Data Type Codes for Advanced Meters||This LPGRR revises the Profile Decision Tree to include Profile IDs that allow Time Of Use Schedules (TOUS) for AMS meters. When 15-minute interval settlement begins for AMS meters, the meter data type codes for Electric Service Identifiers (ESI IDs) with AMS meters will be converted to Interval Data Recorders (IDRs). This request enables ESI IDs with AMS meters to have IDR meter data type codes and Oncor’s TOUS (TOU01, TOU02, and TOU13). It also allows AMS meters with Oncor TOUS to remain Non-Interval Data Recorder (Non-IDR) until such time as the proposed Profile IDs are implemented by ERCOT.||09/14/2009||Chris Rowley with TXU Energy||Yes||Appendix D: Profile Decision Tree||Approved|
|LPGRR036||Delete Document Control Section||This Load Profiling Guide Revision Request (LPGRR) deletes Section 1.1 from the Load Profiling Guide (LPG).||12/30/2009||PWG||No||1.1 (delete)||Approved|
|LPGRR037||Replace Wording Truncated from LPGRR035||
This Load Profiling Guide Revision Request (LPGRR) revises the Profile Decision Tree to include wording that was truncated by Microsoft Excel 2003© during the processing of LPGRR035, Addition of Time Of Use Schedules (TOUS) to Profiles with Interval Data Recorder (IDR) Meter Data Type Codes for Advanced Meters, before LPGRR035 was approved.
Some of the truncated wording was from a previously-approved version of the Profile Decision Tree, while proposed wording was truncated as well. The proposed wording that was truncated was related to allowing Electric Service Identifiers (ESI IDs) with Advanced Metering Service (AMS) meters to have IDR meter data type codes and Oncor’s TOUS (TOU01, TOU02, and TOU13). It also allows AMS meters with Oncor TOUS to remain non-IDR until such time as the proposed Load Profile IDs are implemented by ERCOT.
