period.
ACTION REQUIRED:

prior to Day-Ahead RPRS market for July 1, 2008 Operating Day. Starting at 1800 hours and thereafter,
QSEs are to update Resource Plans on an hourly basis for July 1, 2008 Operating
Day using WGRPP forecasts.

WGRPP forecast to apply as the planned operating level in the Day-Ahead Resource
Plan submitted as input into the Day-Ahead RPRS procurement study. QSEs are to use the WGRPP forecast closest
to the time the QSE submits the Resource Plan before 1600 hours.
HOUR-AHEAD: If ERCOT needs to procure additional
Replacement Reserve Service in the Adjustment Period pursuant to Section
6.6.3.2.1, then QSEs will update the forecasted WGRPP for the Operating Hour
that energy from the RPRS units is required with the latest emailed forecast.
QSEs are to use the most current

Resource Plans hourly. If
Hour-Ahead RPRS is implemented, it will use the Resource Plan at RPRS execution.
QSEs
representing WGRs need to confirm with ERCOT the email address they wish to use
to receive the hourly WGRPP
forecast. QSEs are asked to send
preferred email address to their ERCOT Account Manager or to [log in to unmask]

installation of email address into an automated email system.
