DAYS AFFECTED:  October 1, 2015 and January 1, 2016

LONG DESCRIPTION:  On July 1, 2015, ERCOT received a Notification of Suspension of Operations (NSO) for the following Generation Resources:


The NSO indicated that these two units would be mothballed on a seasonal basis, with a Seasonal Operation Period beginning on May 15 and ending on September 30 each year.  The proposed effective date for the suspension of MLSES_UNIT 1 is January 1, 2016.  The proposed effective date for the suspension of MLSES_UNIT 2 is October 1, 2015.
