ScottishPower Energy Networks (SPEN) is seeking approval for plans to invest £5.2 billion between 2015 and 2023 in its electricity distribution network.
The multi-billion pound investment will renew and maintain the cables and substations that power more than 3.5 million customers in Central Scotland, Merseyside and North and Mid Wales.
The energy supplier currently manages 105,000km of power cables and 30,000 substations, many of which were originally installed between the 1950′s and 1970′s.
The power supplier claims the programme will help create 2,500 jobs and play a major role in supporting the UK’s transition to a low carbon economy whilst reducing costs for customers. It plans to spend around £90 million recruiting and training the thousands of people needed to make the upgrades.
The investment comes on top of £2.6bn being pumped into the high-voltage transmission network between now and 2021.
The energy firm claims it currently has 30% fewer interruptions than the UK average and said it would double compensation payments for customers who lose power for extended periods from 2015.
