Dozens of city centre stores have been plunged into darkness this morning after a huge power cut in Sheffield.
The power cut has hit large parts of the shopping area with Fargate among the worst hit.
Marks and Spencer, HMV, McDonald's and WHSmith in Fargate are among the stores which have been forced to close or allow customers to continue shopping using emergency lighting.
Several shops have posted notices in windows telling customers of the disruption.
Paperchase, New Look and River Island are among some of the other stores affected.
However, the cut appears to be totally at random with many other shops and businesses along Fargate trading as usual - with many outlets adjacent to the disrupted business open as normal.
Marks and Spencer appeared to be allowing customers in using emergency lights while both HMV and River Island displayed closure notices from behind closed doors.
At WHSmith, which is undergoing a refurbishment behind a temporary facade, white trellis gates had been used to close the shop to customers.
The cut means staff have been able to take an impromptu break with many seizing the opportunity to soak up the sun, grab a snack and enjoy a cigarette.
Almost 500 buildings have been affected by the power cut with Northern Powergrid warning that premises in the S1, S6 and S8 areas of Sheffield have been affected.
A Northern Powergrid spokesperson said: "We have restored power to some of the customers affected and continue to work to restore supply to the remaining customers."
The company said that the problem has been caused by a problem with an underground cable.
