| Description: |
In accordance with Protocol Section 4.4.15, QSE Resource Plans, ERCOT shall produce renewable production potential forecasts for Wind-powered Generation Resources (WGRs) to be used as the planned operating level in the Resource Plan during Replacement Reserve Service (RPRS) procurements. Upon approval of PRR763, Use of WGRPP as Planned Operating Level in Day-Ahead Resource Plan for WGRs, ERCOT implemented the WGR Production Potential (WGRPP) forecast without delay by having the WGRPP forecasting service email forecasts directly to each WGR Qualified Scheduling Entity (QSE). The email process proved to cause unacceptable delivery delays and errors for QSEs. This System Change Request (SCR) proposes to provide a secure and programmatic means to supply the WGR QSEs with their forecasts by: o Provide WGR QSEs their forecasts through the zonal Extensible Markup Language (XML) Market User Interface (MUI). o A WGR QSE can obtain its current forecasts by submitting a query through the zonal XML MUI. o This will be through a query as specified in the "ERCOT Participant Interface: XML" document. o Past forecasts will not be available after each hour. o ERCOT may restrict the frequency of these queries to protect system availability. |
| Reason: | The current email solution is unreliable and cumbersome. The email process proved to cause unacceptable delivery delays and errors for QSEs. |
