Resource Registration - CC Changes and Impact

• Combined Cycle units have the opportunity to
  submit registration for all configurations
• Usage of configurations downstream is not
  confirmed
• What does this mean?
• All Combined Cycle facilities will need to
  complete an addendum for all desired
  configurations (including those included on the
  RARF)
• The addendum will be the source of all
  configuration information in the final RARF
• Transition information will be resubmitted as
  well
• ERCOT will host a WebEx to provide an example of
  configurations and transitions as well as to
  answer questions
• ERCOT will provide opportunities for individual
  assistance in completing the addendum
