DEESIDE POWER - OPERATIONS - Control Room and Technical Details
______________________________________________________________

Using modern computer systems the whole station can be started up and run automatically. The hot gas turbine units can start-producing electricity within 15 minutes and be at full output within an hour. The operators in the control room monitor the running of the plant and if necessary, make operational changes using the latest computer technology.

Staff in the control room are part of a 24-man power station team which keep the plant running 24 hours a day, 7 days a week. Care was taken in staff selection and great emphasis placed on their training. All the staff recognise the need for teamwork, flexibility and commitment to ensure Deeside's commercial success.
