Nearly 1,000 homes in Lancaster lost power overnight on Sunday, August 9, following an underground cable fault.
Most homes in streets including Denmark Street, Kennedy Close, Ashton Road and Oaklands Court were re-connected within nine hours of the outage.
Residents took to social media with reports of house and car alarms going off several times during the night in Abraham Heights, Aldcliffe, Scale Hall and the Morecambe Road areas.
Ten homes are still without power today, Monday August 10, and Electricity North West, the company responsible for the electricity supply in the north west of England, said it was working to get the connection back as soon as possible.
A spokesperson for Electricity North West said: “An underground cable fault caused the loss of power to 941 customers in Lancaster at 2.30am.

“The majority of customers were restored by 11.20am and engineers are still onsite working to get the remaining ten customers back on by generator as quickly as possible.
