Description:
Forecasted Net Zonal Energy - information will be available for each 15-minute interval of the upcoming Operating Period, one hour prior to the start of each Operating Period (or on whatever timeline ERCOT runs its short-term load forecasting routine to update its forecasted load). The information should be based on ERCOT™s Forecasted Zonal Aggregate Load and ERCO€™s trend of aggregate zonal generation. Separately, the Working Group is also requesting that ERCOT make available a written description of the methodology, including distribution factors, used in converting from Load Areas to Zones.
Actual Zonal Generation - This information will be available in real-time on the same timeline as other information regarding frequency control that is already being provided by ERCOT (i.e., every few seconds). This information will be based on SCADA data.
Reason:
QSEs desire increased transparency of ERCOT operations and, accordingly, the timely availability of real-time operating data. The ERCOT QSE Project Managers™ Working Group has identified a basic set of operating data €œData Requiremenâ€?) that is still not available to the market. The Working Group has requested ERCOT make the data available as expeditiously as possible. This System Change Request formally responds, in part, to the Working Grp’s informal request of ERCOT in February 2002 (see February meeting minutes of QSE Project Manars’ Working Group)
