- Owner Communication Plan*
- *
Load Dispatcher Notifications
Owner QSE’s (NRG South Texas LP, City Public Service Board of San Antonio (CPS), and City of Austin (COA)) shall be notified by an EMS Website update of imminent, in-progress or completed power reductions of greater than 25 Mwe (non-peak)/ >5 Mwe (peak), unit/plant shutdowns, or other changes in scheduled power generation.
First notifications should be made via the EMS Website, then follow-up by telephone, as required, to Owner QSEs if needed for clarification.

STA Responsibilities (when activated)
Provide advisory technical support to the Shift Manager.
Maintain cognizance of plant and equipment status.
Perform a review of planned activities and make appropriate recommendations to the Shift Manager, (including if special considerations or precautions are warranted).
Monitor Critical Safety Functions (CSF’s)
Monitor EOP progression to ensure transitions are correct.
Monitor Conditional Information Page
Immediately inform Unit/Shift Manager upon reaching an Orange or Red path condition.
Communicate CSF status during transition between EOP’s.
Make a qualitative assessment of plant parameters during and following plant events and transients to determine correct plant response and potential core damage.
