DATE:  November 16, 2009

NOTICE TYPE:  M-A0814-02 General   

SHORT DESCRIPTION:  Integration of wind plant availability in the AWS wind forecast for Wind-powered Generation Resources which are Jointly-Owned Units

INTENDED AUDIENCE:  Resource Entities and QSEs with Wind-powered Generation Resources

DAY AFFECTED:  November 20, 2009

LONG DESCRIPTION:  In order to improve the wind forecast in the zonal system, AWS and ERCOT have established the ERCOT Wind Plant Availability Website. Starting at 12:00 PM on November 20, 2009, AWS will be incorporating the wind plant’s availability information into the forecast for participating Wind-powered Generation Resources (WGRs) which are Jointly-Owned Units (JOUs).  JOUs are all WGRs which have a “_J0x” suffix as part of the Resource name. If a JOU’s availability data is not provided by their Qualified Scheduling Entity (QSE), AWS will assume full availability as it has been doing thus far.

ACTION REQUIRED:  QSEs representing Jointly-Owned WGRs should ensure that they have received the correct login information for the ERCOT Wind Plant Availability Website and should be familiar with the provided User Guide.

ADDITIONAL INFORMATION:  When moving to the Nodal system, the QSE/RE will be required to report wind plant availability (planned outages, maintenance and forced outages) in the ERCOT outage scheduler according to section 3.1.2, 3.1.4.5, and 3.1.4.8 of the Nodal Protocols. AWS and ERCOT have established the Wind Plant Availability Website in order to improve the current Zonal wind forecast. At this time, participation is on a voluntary basis unless or until the Zonal Protocols are amended to require participation. Although entry of WGR availability is voluntary, AWS and ERCOT strongly encourage QSE participation in order to achieve optimal wind forecasting. 

All QSEs with Jointly-Owned WGRs will be contacted prior to Wednesday, November 18, 2009, by ERCOT Client Services and provided with individual ERCOT Wind Plant Availability Web Site login information, if necessary, as well as with an updated User Guide with a section on entering availability flags for JOUs.

CONTACT:  If you have any questions, please contact your ERCOT Account Manager. You may also call the general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client Services via e-mail at [log in to unmask].
