Overhead cables across a large part of Greater Manchester and Cheshire are to be upgraded as part of a multi-million pound overhaul which will help secure electricity supplies across the North West region and beyond .
Engineers will start work on the projects to refurbish two lines of 36 and 51 pylons spanning 30kms in August.
Preparation is already underway with National Grid writing to home and business owners to let them know what to expect.
The first project will see 11km of overhead power line between electricity substations in Whitegate, near Chadderton and Rochdale in Greater Manchester and should be complete by the end of October.
New wires and fittings will be installed on the 36 pylons that make up the line that has been in constant service for nearly 50 years at a cost of £12 million. Electricity supplies will be unaffected by the work and no new pylons will be built.
Over the next three months, some trees and vegetation will be cut back and trackways laid to provide temporary access for workers, machines and materials. Ecology surveys have been carried out to make sure the project causes as little disturbance as possible to local wildlife and work will comply with environmental legislation.
“The wires and the fittings on the pylons are now reaching the end of their lifespan so we are going to install new ones to ensure that power continues to flow uninterrupted”
The second project, scheduled for completion before Christmas, will focus on a 19km long overhead power line between electricity substations in Frodsham and Capenhurst in Cheshire.
Martin Bretherton, National Grid Project Manager, said: “The wires and the fittings on the pylons are now reaching the end of their lifespan so we are going to install new ones. This will ensure that power continues to flow uninterrupted along this line, helping keep the lights on.”
