Energy chiefs have apologised after a power cut affected a large part of the Chesterfield area last night.
Hundreds of homes in the S40 and S41 areas were without power for about two hours because of a fault with an 11 kilovolt underground cable.
Engineers from Western Power Distribution (WPD) worked to re-route supplies.
Power was back on by about 10pm.
A WPD spokesman said: “We’d like to thank customers for their patience and apologise for the inconvenience caused.”
