NOTICE DATE: May 4, 2010 NOTICE TYPE: M-A042710-02 PRR SHORT DESCRIPTION: Follow-up to WGR Turbine SCADA Implementation of PRR830 INTENDED AUDIENCE: QSEs Representing WGRs and Resource Entities DAY AFFECTED: June 1, 2010 LONG DESCRIPTION: This Notice will provide additional information regarding implementation of Wind-powered Generation Resource (WGR) telemetry for turbine availability. Protocol Section 6.5.7.1(10) requires WGRs to provide the following Real-Time SCADA points to ERCOT via the WGR's Qualified Scheduling Entity (QSE) ICCP data link: * The number of wind turbines that are available for real power and/or Reactive Power injection into the ERCOT Transmission Grid * The number of wind turbines that are not able to communicate and whose status is unknown; and * The number of wind turbines out of service and not available for operation. WGRs are to comply with the requirements of paragraph (10) by no later than June 1, 2010. Similar to the implementation of MET data telemetry, ERCOT prefers that these new data points be added to the Nodal ICCP telemetry set. This will forego having this data sent across both zonal and Nodal data links. For affected QSEs who will not be able to provide this data over Nodal ICCP by June 1, ERCOT requests the QSE provide an implementation plan. This plan may be sent to your ERCOT Account Manager. Example ICCP format is as follows: Wind Turbine Info WT No. of Turbines Online NTON INDX DiscreteQ ACMEWT_WNDSUB_UNIT1_NTON No. of Turbines Offline NTOF INDX DiscreteQ ACMEWT_WNDSUB_UNIT1_NTOF No. of Turbines Unknown NTUN INDX DiscreteQ ACMEWT_WNDSUB_UNIT1_NTUN ERCOT will add these new telemetry requirements to the Nodal ICCP Handbook and other related documentation as applicable. ACTION REQUIRED: All WGRs must begin sending the required Real-Time SCADA points via ICCP, at a frequency of 10 seconds, no later than June 1, 2010. SCADA points are to be sent via the WGR's QSE ICCP data link to ERCOT. If the WGR's QSE is not currently able to provide this data through ICCP, the QSE should contact its ERCOT Account Manager to develop a solution.

Although PRR830 has been appealed by certain Entities representing Wind-powered Generation Resources (WGRs) to the Public Utility Commission of Texas (pending PUC Docket No. 37817), only the December 31, 2010, deadline for compliance with the Reactive Power capability requirement for existing WGRs has been suspended while the PUC docket is pending. See Order No. 6 in Docket No. 37817. The remaining portions of PRR830 were effective on December 1, 2009. As such, this Notice is to remind WGRs of Protocol Section 6.5.7.1(10) which requires WGRs to provide a Real-Time SCADA point that communicates to ERCOT the number of wind turbines that are available for real power and/or Reactive Power injection into the ERCOT Transmission Grid. WGRs must also provide two (2) other Real-Time SCADA points that communicate to ERCOT the following: (a) The number of wind turbines that are not able to communicate and whose status is unknown; and (b) The number of wind turbines out of service and not available for operation. WGRs must comply with the requirements of paragraph (10) by no later than June 1, 2010. ACTION REQUIRED: All WGRs must begin sending the required Real-Time SCADA points via ICCP no later than June 1, 2010. SCADA points are to be sent via the WGR's Qualified Scheduling Entity (QSE) ICCP data link to ERCOT. CONTACT: If you have any questions, please contact your ERCOT Account Manager.
