The Generators

The original installation was of three diesel generators providing a total output of 350kW. These would be used in the event of a failure of the public electricity supply. A fourth generator providing a further 150kW was added later. The aim was to restore power within 15 seconds to important areas such as studios, the Control Room and Switching Centre.
