M Group has secured a £110 million contract from ScottishPower for major overhead line upgrades across central and southern Scotland.
The project is part of Britain’s biggest rewiring since electrification and places us at the centre of a vital electricity infrastructure programme.
We’ll be replacing more than 70 km of overhead line on ScottishPower’s strategic Strathaven to Smeaton route, which runs from South Lanarkshire to East Lothian. This overhead line is one of the main power corridors between Glasgow and Edinburgh.
The work will help increase Britain’s capacity to move power around the country, strengthen the local network for communities and increase energy security, while supporting investment in new supply chain jobs and facilities.
ScottishPower is investing £24bn in the UK to 2028 as it pushes ahead on the biggest rewiring the country has seen since electrification.
This investment is just one example of the ongoing work to upgrade our electricity grid, which is essential to power homes and businesses with clean, secure energy we control.
It is also an enormous economic opportunity - boosting supply chains here in the UK and providing jobs and investment in communities right across the country.”
UK Government, Minister for Energy, Michael Shanks
We’re delighted to play a central role in delivering this crucial upgrade to one of Scotland’s most important electricity corridors. Our highly skilled teams will fully refurbish the 400kV Strathaven to Smeaton overhead line, replacing components first installed in the 1960s and deploying advanced high-capacity technology to support future demand.
Delivering this work with SP Energy Networks not only secures skilled jobs for our people and supports local employment, but also highlights our commitment to safe, efficient delivery on a project that will underpin the energy network for years to come.”
David Maddocks, Managing Director - Overhead Lines, M Group
This contract award to M Group is representative of the kind of economic growth being generated by our £12 billion investment in upgrading the electricity transmission infrastructure in central and southern Scotland.
We’re committed to maximising the opportunities for suppliers up and down the country, modernising the transmission network, while unlocking growth and supporting more highly skilled, high-quality jobs.”
Guy Jefferson, Transmission Managing Director at SP Energy Networks
