More than 160 homes in Darwen have been left without power this morning (November 28).
Engineers from Electricity North West are on site and expect to have power restored by 9am, the company said.
The incident was first reported at around 5.50am today and has left 169 properties without power.
A spokesperson for Electricity North West said: "This power cut has been caused by an unexpected incident on the high voltage cable that provides electricity to your home or business.
"We didn't know before your electricity went off that this was going to happen but now we know, rest assured we will get your power back on safely and as quickly as possible.
"Please be aware that all our timescales are estimated based on previous experience and may change if new information becomes available while our engineers are fixing the issue.
"With high voltage power cuts, we're often able to get many of the homes involved back on before our estimated time of restoration."
