Wind Operations Task Force Recommendation to ROS, 15 May 2008
Question #2: All QSEs including wind QSEs MUST be vigilant in updating their Resource Plan and keeping it accurate.

Consensus view:  Instead of expecting wind QSEs to frequently update their Resource Plan with the latest version of a constantly changing scenario, ERCOT staff will use a weather-based forecast from AWS TruWind and inform the QSE once a day of the expected output its each of its wind resources.  The wind QSEs will then be required to update their respective Resource Plans accordingly.  A PRR has been drafted and is included with this recommendation.  This PRR also accelerates the change from a 50% confidence level to an 80% level (20% probability), which TPTF narrowly approved for Nodal.  The primary protocol affected is 4.4.15 “QSE Resource Plan”.  The affected Operating Guides and Shift Supervisor Procedures have not been identified.

The WOTF recommends adoption of the PRR, but also recommends reviewing the change to the 80% confidence level when more comparative data is available.

Description of PRR

QSEs representing WGRs shall update their Resource Plans and Schedules to reflect the expected wind generation production after the close of the Replacement Reserve market. The energy schedules submitted for wind resources should correspond with the Resource Plan scheduled energy output in order for real-time balancing and the operator entered offset to perform properly.
ERCOT shall provide forecasts for each WGR to the QSEs representing WGRs and shall deliver the forecasts before Replacement Reserve Procurements to allow the QSEs to update the WGR Resource Plans.  QSEs shall use the ERCOT-provided forecasts for WGRs as the planned operating level for the 1600 Resource Plan and as requested by the ERCOT Operators.
