Subject:	Changes to Day-Ahead Scheduling Timeline

This is to announce a change in the ERCOT day-ahead scheduling timeline

The following is a description of the changes:

self-arranged Ancillary Services and AS bids selected by ERCOT.  This
activity is currently scheduled to occur at or before 1400 of the
day-ahead period.  The timeline for this activity will be changed to be
at before 1500.
*	Submission of Resource Plans with non-binding unit-specific
information and submission of Replacement Reserve Service (RPRS) bids.
This activity is currently scheduled to occur at or before 1430 of the
day-ahead period.  The timeline for this activity will be changed to be
at before 1600.
*	Close of Day Ahead Market. This activity is currently scheduled
to occur at or before 1630 of the day-ahead period.  The timeline for
