<b>Solar Power Production - Hourly Averaged Actual and Forecasted Values by Geographical Region</b><br/><br/>This report is posted every hour and includes System-wide and geographic regional hourly averaged solar power production, STPPF, PVGRPP, and COP HSL for On-Line PVGRs for a rolling historical 48-hour period as well as the system-wide and regional STPPF, PVGRPP, and COP HSL for On-Line PVGRs for the rolling future 168-hour period. System-wide and regional generation, are included in this report under column labels with "GEN_" prefixes. ERCOT's forecasts attempt to predict HSL, which is uncurtailed power generation potential. Since generation is impacted by curtailments, the data in this report should not be used to evaluate forecast performance. Steps will be taken to include HSL in this report in the future.
