Homes are without power as outages have been reported in Brampton and Wigton.
Power failure has been reported in multiple postcodes due to two electrical faults.
An estimated 68 homes have been affected by a fault with overhead powerlines in Brampton.
Electricity North West has said that power-cuts have been caused by "an unexpected incident on our high voltage cables which provide electricity to your property."
Crews will soon be arriving on-site in Lanercost and power is expected to return to homes tonight.
An issue in Wigton has seen 2,000 customers affected by brief outages from around six o'clock. Works are underway to fix the fault.
The power cut in Brampton has now been resolved.
