More than 1,000 homes and businesses lost power in Preston after a fire at a substation this morning (October 23).
The fire happened at a substation in Kent Street at 5am, after thieves gained entry and attempted to steal electrical equipment.
Two fire engines from Preston and Penwortham battled the blaze for two hours and King Street had to be cordoned off for safety.
A spokesman for LRFS said: "We have isolated the electrics to make the scene safe for engineers from Electricity North West.
"It looks like the power will remain off for a good part of the day for some of the businesses in the immediate area.
"A cordon has been put in place and the road will likely remain closed this morning."
Electricity North West said 1,000 customers initially lost power, but supplies were restored to the vast majority of homes and businesses by 7.44am.
It said 149 properties are currently without supply in the PR1 post code area. The supply is expected to be fully restored by 1pm.
Electricity North West said the power cut and fire was caused by a break in at the substation, where thieves caused significant damage to the electrics.
Engineers arrived on site at around 7am to assess the damage and begin repairs.
A spokesperson for Electricity North West said: “A break in at the Kent Street substation in Preston at 5.11am this morning caused a fire which led to a power cut affecting 1,149 customers.
"We believe somebody attempted to steal electrical equipment and significant damage has been caused.
"Our engineers attended site immediately and worked alongside the local fire service who attended and were able to put out the fire.
"At 7.44am, we were able to restore power to 1,000 customers and engineers are working hard to restore power to the remaining 149 customers.
"If anybody saw anything in regards to the break in, we ask them to contact Lancashire Police."
Police said the fire had been caused by thieves attempting to steal copper wiring.
A police spokesman said: "We were called at around 5.40am today (Wednesday, October 23) to reports of a burglary and fire at an electricity substation on Kent Street, Preston.
"It looks like someone has broken in and attempted to steal some copper wiring, which has caused a fire.
