NOTICE TYPE:
M-D042309-02 Notice of System Change (PRR/SCR)
SHORT DESCRIPTION:
Implementation of SCR 754, Replace Email Delivery of WGRPP Forecasts –
MOTE Testing
INTENDED AUDIENCE:
Resource Entities with Wind-powered Generation Resources and QSEs
DAY AFFECTED: June 24,
2009
LONG DESCRIPTION: ERCOT
has implemented an XML query for Qualified Scheduling Entities (QSEs)
representing Wind-powered Generation Resources (WGR) to download hourly WGR
forecasts required per PRR 763 and SCR 754. The XML query as specified in
the ERCOT Participant Interface: XML query Section 6.5 (Query for AWS Wind
Forecast) was sent through a market notice on April 23, 2009.
The
implementation is intended to remedy the limitations of email delivery of AWS
wind generation forecasts to QSEs by employing zonal infrastructure and
processes for production quality 7x24 delivery.
Each
QSE representing WGRs is encouraged to test and prove their XML query in the
ERCOT Zonal Market Operations Test Environment (MOTE) at this time in
preparation for migration to the production system for normal data
queries. Migration to the production system is scheduled for June 24,
2009.
The
URL for MOTE is https://mostest.ercot.com/ercot-xml/servlet/Listener.
You will need a digital certificate from ERCOT Client Services to access
MOTE. A test data set is available in MOTE.
ACTION REQUIRED: Implement
the ERCOT Participant Interface: XML query described in Section 6.5 (Query for
AWS Wind Forecast) for MOTE testing at this time.
ADDITIONAL INFORMATION:
The current method of email delivery of AWS forecasts will remain until all
QSE’s with WGRs are able to retrieve the forecasts using the XML query.
