A power cut on Thursday, April 26, affected over one thousand buildings in Lincoln for up to half an hour.
The cut happened at around 1pm, and affected 1,500 properties in the city centre and the east of Lincoln.
Places reported to be most affected were Lincoln High Street, Monks Road, Outer Circle, Clasketgate, Glebe Park and Sincil Bank.
Residents in areas such as Birchwood and North Hykeham also experienced flickering in their homes.
Some residents noted that their power went on and off more than once before coming back on permanently.
The fault was located to a 11,000 volts cable in Waterside South.
A Western Power Distribution spokesman said: “At 1pm we were made aware of a fault at our 11,000 volts cable at Waterside South. It resulted in 1,500 properties remaining without power.
“Most of those (1,200) were automatically restored in one minute, but there were a few properties that were without power for around 30 min.”
“At this stage engineers are on the scene investigating,” he added.
