Close to 500 homes in Croston are without power after severe floods hit an electricity sub-station.
Engineers from Electricity North West are on-site trying to combat the situation. Electricity has been restored to 89 houses, with 488 still without power.
Army personnel were called in to the village yesterday after the River Yarrow burst its banks.
Residents were forced to evacuate their homes. A rest centre providing food and hot drinks for people affected by the flood and loss of power has been set up at Croston Sports Club.
They are just some of the 6,462 residents in Lancashire and Greater Manchester whose power has been cut off by floods caused by non-stop torrential rains on Boxing Day.
Electrcity North West engineers have warned that some properties may not have their power restored until Monday due to the severity of the floods.
Mark Williamson, operations director for Electricity North West, said: “Our engineers have worked through the night and will continue to work today in extremely difficult conditions to restore power to the remaining customers in Lancashire and Greater Manchester.
“There are still a number of substations that are flooded and we can’t get access, but as soon as the water recedes then we have teams ready to go in and check the damage and make repairs.”
Police are urging people to remain calm while the full extent of flood damage is assessed.
A Lancashire Police spokesman said: “Contact police immediately if you have concerns about any vulnerable or elderly residents in the area. Neighbours are being asked to check on neighbours.
“If you can’t get in touch with a friend or relative and are worried, please contact police on 101 and we will visit their homes.”
