combinedCycle N string Combined cycle Not required. Value ignored if provided.
deleteTPOs N Boolean Set to true if three part offers for resource are to be deleted 1 or 0 (default=0)
EnergySchedule/startTime N dateTime Not Used Not Used
EnergySchedule/endTime N dateTime Not Used Not Used

EnergySchedule/

TmPoint/time

 Y dateTime Absolute time for start of interval Valid time between startTime and endTime for schedule

EnergySchedule/

TmPoint/ending

 N dateTime Absolute time for end of interval Valid time between startTime and endTime for schedule

EnergySchedule/

TmPoint/value1

 Y float Megawatts >= 0

The following is an XML example for an OutputSchedule:
