Several roads in Eastbourne were closed and homes left without power after an electricity substation exploded yesterday evening (Friday).
There was an explosion at the sub station close to Bridgemere Road and Churchdale Road shortly after 6pm and police believe it has been totally destroyed.
Roads around the area were closed off while police, fire crews and officials from the electricity board were at the scene surveying the damage.
It was not known last night whether homes would have to be evacuated but many have been left without electricity.
