These contracts will enable SP Energy Networks to grow long-term partnerships with UK businesses, facilitating upgrades necessary for rewiring Scotland’s electricity infrastructure.
The initiative will provide additional capacity for new homes, businesses and clean energy projects while enhancing power distribution efficiency across the country and reducing reliance on fossil fuels.
SP Energy Networks CEO Nicola Connelly said: “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.
“This is great news for the UK and Scottish supply chains, with every pound spent directly benefitting central and southern Scotland and its infrastructure for decades to come.

By GlobalData“These contracts are not just about infrastructure – they are about enabling a cleaner, greener Britain. We are proud to be leading the charge in helping deliver the UK Government’s Clean Power 2030 ambition.”
The scope of work under the contracts includes constructing new high-voltage substations and overhead lines as well as the design, engineering and electrical works.
The alliances will run for five years but could extend to ten, providing stability that encourages investment in skills and innovation among suppliers.
Morgan Sindall Infrastructure will be the exclusive contractor for both substations and overhead lines on the Denny to Wishaw project.
Energy Minister Michael Shanks said: “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SP Energy Networks partnerships take us a step closer to reaching clean power by 2030, in modernising the country’s outdated network to get more of clean power generated in Scotland to homes and businesses across the country.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.”
The announcement follows ScottishPower’s pledge to increase its investment in the UK to £24bn by 2028.
The company has submitted to UK energy regulator Ofgem a five-year business plan for 2026–31 that supports achieving Clean Power 2030 goals set by the government.
In April 2025, Ofgem was contemplating enforcing penalties against a joint venture between National Grid Electricity Transmission and SP Energy Networks due to delays in completing the Eastern Green Link 1 project.
