All properties affected by Lancaster substation flooding now restored, although some properties' supply may still be off due to other local issues such as flooding.
1,514 properties remain without power in Cumbria, and customers whose power supply is back on are being asked to use it sparingly until further notice.
At around 10.45am, engineers from Electricity North West reported that they had restored power to all areas of Lancaster affected by flooding to the area's main substation, but some local faults affecting a handful of properties may mean that a number of customers remain off supply.
Lancaster University, four commercial properties and "a handful of homes" are still without power though.
Mark Williamson, operations director at Electricity North West, said: "We've now restored the vast majority of homes and businesses in Lancaster although we are aware of some affected by local issues that remain without power.
"The substation is back online but not yet operating at full capacity. That means we need customers to conserve power as much as possible until we can fully complete repairs on the substation. We will provide further updates throughout the day."
Electricity North West engineers are continuing to work to get the substation back up to full capacity and aim to complete this essential work by late this evening.
Mark added: "We know this has already been a very trying time for people in Lancaster and we are still doing everything we can to bolster supplies. In the meantime we ask that if you do have power, please use it sparingly and just for essentials until further notice."
Teams from Electricity North West are also working in Cumbria to restore power to the remaining properties affected in the county after flooding cut power to a number of local substations.
A spokesman from Electricity NW added that "he can't stress this enough": Do not use any electical items at the moment that aren't essential. These include things like tumble driers, dishwashers, Christmas lights, etc. He added that if your property has no power - but neighbouring properties do, check your trip-switches first, before calling engineers. If your trip-switches are on, only then should you call 0800 195 4141.
