This report provides the Load and Resource inputs used by ERCOT to determine the need to issue an Advanced Action Notice (AAN) or Outage Schedule Adjustment.

This report is posted after every SCED run and includes the sum of the HDL and the sum of the LDL for all Generation Resources On-Line and Dispatched by SCED.

Hourly aggregated wind and solar power output for ERCOT for the year,

This report is posted every hour and includes system-wide and regional STPPF and PVGRPP values produced by each forecast model for On-Line PVGRs for the rolling future 168-hour period and also indicates which forecast model is used for each region to populate COPs.

This report is posted every hour and includes system-wide and regional STWPF and WGRPP values produced by each forecast model for On-Line WGRs for the rolling future 168-hour period and also indicates which forecast model is used for each region to populate COPs.

This report is posted every 5 minutes and includes system-wide and solar region aggregations of the Intra-Hour Photovoltaic Power Forecast (IHPPF) for the next two hours, with five minute resolution.

Intra-Hour Wind Power Forecast (IHWPF) by wind region that provides a rolling two hour, five minute forecast of ERCOT-wide wind production potential.

This report is posted every 5 minutes and includes system-wide and geographic regional 5-minute averaged solar power production for a rolling historical 60-minute period.

This report is posted every 5 minutes and includes System-wide actual 5-minute averaged solar power production for On-Line PVGRs for a rolling historical 60-minute period. Our forecasts attempt to predict HSL,

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.

This report is posted every hour and includes System-wide actual hourly averaged solar power production, STPPF, PVGRPP, and COP HSLs for On-Line PVGRs for a rolling historical 48-hour period as well as the System-wide STPPF, PVGRPP and COP HSLs for On-Line PVGRs for the rolling future 168-hour period. Our forecasts attempt to predict HSL, which is uncurtailed power generation potential. Actual system-wide generation, which is included in this report as “ACTUAL_SYSTEM_WIDE” or “SYSTEM_WIDE” is impacted by curtailments. Because of this, the data in this report should not be used to evaluate forecast performance. Steps will be taken to include Actual System-wide HSL in this report in the future.

Hourly Maximum Resource Capacity Available for Planned Outages within 7 days of the Operating Day

Daily Maximum Resource Capacity Available for Planned Outages for 7 days to 60 months of the Operating Day

One Business Day following the approval or cancellation of a Transmission Facility’s Outage or Resource Outage which requires a DC Tie Outage or DC Tie derate, ERCOT shall post the following information on the MIS Public Area

This report includes all approved and accepted Planned, Forced and Maintenance Resource outages. The report excludes Resource outages for retirement of old equipment, seasonal mothballed (during the outaged season) and mothballed.

Methodology for Calculating Maximum Daily Resource Planned Outage Capacity

This report contains a snapshot of all unplanned Resource outages (i.e., Forced Outages and Maintenance Outages) and derates that were active in the Outage Scheduler at any time on the third day before the posting date of this report. The data for these outages is submitted by operators of generation assets and is used by ERCOT staff in the operation of the Texas power grid. This report does not contain Resource outages for generators that are no longer operational on the Texas power grid or have not begun operating on the Texas power grid. This report contains all outages for Resources that are required to enter outages in the ERCOT Outage Scheduler including Generation Resources in Private Use Networks, and Energy Storage Resources. Some smaller operational derates are not required to be reported.

An hourly Reliability Unit Commitment (RUC) report containing the sum of the HSLs of Generation Resources that are online in the most recent SCED execution and indicated as offline in its COP, for each hour of the RUC study period. Online SCED statuses are ONRUC, ONREG, ON, ONDSR, ONOS, ONOSREG, ONDSRREG, FRRSUP, ONTEST, ONEMR, ONRR, ONOPTOUT, STARTUP, and OFFQS. Offline COP statuses are OFF, OUT, and EMR.
