NOTICE DATE: January 29, 2010
NOTICE TYPE: M-A012910-01 PRR
SHORT DESCRIPTION: Implementation Details of PRR811
INTENDED AUDIENCE: QSEs Representing WGRs and Resource Entities
DAY AFFECTED: February 1, 2010
LONG
DESCRIPTION:
PRR811 requires that a new
value be sent to ERCOT by each Wind-powered Generation Resource (WGR). This
value is referred to as the Real Time Production Potential (RTPP). A Qualified
Scheduling Entity (QSE) must be selected by the WGR so that the RTPP can be
sent to ERCOT through the QSE.
To
implement PRR811 without requiring a new SCADA analog point, the RTPP shall be
telemetered to ERCOT using the MWH point for all WGRs. This will not have an
effect on ERCOT’s reserve calculations. This solution will not require a
delay for an Energy Management System (EMS) database load.
ACTION REQUIRED: All WGRs should be prepared to begin calculating
RTPP as per the Protocols and start providing it to their QSE on February 1,
2010. Additionally, QSEs who have been selected to provide the RTPP for a WGR
should be prepared to begin sending the RTPP value to ERCOT using the existing
SCADA analog point starting on February 1, 2010, or as soon as possible.
