SP Energy Networks has awarded supply chain contracts as part of a £1.4 billion ($1.7 billion) commitment to deliver critical onshore transmission projects across central and southern Scotland.

The contract is part of a wider £5.4 billion ($6.4 billion) supplier investment programme announced by the company that will run over the next decade.

The programme aims to upgrade the transmission grid and unlock capacity for new homes, businesses, and clean energy projects in the UK, move power around the country more efficiently, reduce reliance on fossil fuels and boost energy security.

SP Energy Networks wants to build long-term partnerships with UK businesses to fulfil its ambition to rewire the networks.

Commenting on the announcement was Nicola Connelly, CEO SP Energy Networks: “These strategic partnerships give suppliers the confidence to invest in themselves – growing their workforce, opening new offices across the country and creating even greater opportunities for the UK.”

Connelly called the contracts a “defining moment for our energy future.

“These contracts are not just about infrastructure—they’re about enabling a cleaner, greener Britain. We’re proud to be leading the charge in helping deliver the UK Government’s Clean Power 2030 ambition.”

The contracts cover a wide range of critical grid infrastructure, including:

  • New and upgraded high-voltage substations
  • Overhead line construction
  • Design, engineering, construction, and electrical works

The strategic partnerships will initially run for five years, with the option to extend to 10, providing long-term certainty for suppliers and enabling them to invest in skills, technology, and innovation, with 17 of the 19 suppliers based in the UK.

Said UK energy minister, Michael Shanks: “These SP Energy Networks partnerships take us a step closer to reaching clean power by 2030, in modernising the country’s outdated network to get more of clean power generated in Scotland to homes and businesses across the country.

“This is the clean power transition in action – investing in British supply chains that will bring skilled jobs and economic growth to communities in Scotland and beyond.”
