MORE than 1,000 residents spent last night (Wednesday) without electricity following two power failures.

Homes in the Welwyn, Oaklands, Woolmer Green and Knebworth areas were plunged into darkness yesterday afternoon after a high voltage cable failed.

Energy suppliers EDF Energy managed to solve the problem within two hours, only for a second fault to occur at around 8.30pm.

It took a further 12 hours for engineers to reconnect residents.

An EDF Energy spokeswoman said: "Power was interrupted to 1,346 customers in the Knebworth area at 6.42pm yesterday, due to a fault developing on a high voltage underground cable.

"Engineers restored power to the majority of customers affected within two hours but, regrettably, a second fault occurred at 8.29pm, this time on a piece of equipment within a substation.

"This required our engineer to isolate the power to several hundred further customers so that a repair could be carried out safely.

"Our staff worked on site throughout the night to complete repairs, and restored power to customers in stages, until all supplies were on by 8.30am today.

"We do appreciate how difficult it is to be without power and would like to apologise for the inconvenience caused.
