"UK Power Networks engineers worked as quickly and as safely as possible to restore power to 393 customers.
"Power was restored in stages, with the final 205 properties having their power back at around 22.20pm in the evening.
"We appreciate how difficult it is to be without and apologise for the inconvenience caused."
