FiFTY firefighters from both East and West Sussex Fire and Rescue Services have been tackling a fire at Shoreham power station which broke out shortly after 8.30m last night (Thursday).
The fire was in an auxiliary building at the site which is not being used to generate electricity.

A small number of workers were on site when the fire started. All have been safely accounted for and there are no reports of any injuries.
Firefighters wearing breathing apparatus operated an inbuilt fire suppression system in the building which knocked down most of the fire.
Ground monitors were also used to bring the fire fully under control, and it is now out.
Six fire engines and an Aerial Ladder Platform were mobilised to the scene, plus support vehicles.
Sussex Police provided an overview of the fire with footage taken from the South East Air Support Unit helicopter Hotel 900.
A cordon was set up around the site for public safety but there was no need for nearby homes to be evacuated.
The cause of the fire is under investigation.
