NOTICE DATE: May 29, 2009
NOTICE TYPE: M-A052909-01 PRR
SHORT DESCRIPTION: Reminder - Implementation
Details of PRR803, Revised
Implementation Approach for PRR601
INTENDED AUDIENCE: QSEs and Resource Entities
DAY AFFECTED: July 1, 2009
LONG DESCRIPTION: PRR803 is changing the ramping period
for Balancing Energy Service deployment for Base Power Schedule Calculation and
Balancing Energy Power Schedule from ten (10) minutes to fourteen (14)
minutes. This change is designed to provide more efficient dispatch and to
allow the deployment of more Balancing Energy Services.
QSEs
may test their systems prior to implementation of PRR803 to ensure
compatibility with the new fourteen (14) minute ramping period; however,
testing is not required. The attached document (PRR803 - 14 Minute Ramp Rate
Testing Approach Overview) outlines the testing options and the scheduling
process. The testing period is July 1, 2009 through September 30, 2009.
Regardless of whether system testing is performed, all QSEs will be required to
submit documentation demonstrating that their systems are compliant with PRR803
prior to the proposed implementation date of October 29, 2009.
Due
to only a few responses being received from QSEs to date, ERCOT requests that
QSEs provide the information listed below by June 5 to supply ERCOT staff with
the information needed to support QSE preparation. ERCOT will provide an
update on this preparation at the June QMWG and WMS meetings.
ACTION REQUIRED: To schedule a systems test, QSEs should contact
their ERCOT Wholesale Account Manager. The QSEs will be responsible for
making any necessary arrangements with their Resource Entities.
