SP Energy Networks has announced a significant £1.4 billion investment dedicated to advancing critical onshore transmission projects across central and southern Scotland.

This substantial commitment aims to accelerate the delivery of the UK Government's ambitious Clean Power 2030 mission.

This funding forms part of SP Energy Networks' broader £5.4 billion supplier investment programme over the next decade, designed to modernise and expand the electricity grid. The recently awarded supply chain contracts are set to forge long-term partnerships with UK businesses, central to rewiring the nation's electricity network. This multi-billion-pound initiative will unlock increased capacity for new homes, businesses, and clean energy projects, improve power distribution efficiency, and significantly reduce the UK's reliance on fossil fuels while boosting energy security.

To mark this pivotal announcement, Nicola Connelly, CEO of SP Energy Networks, was joined by Energy Minister, Michael Shanks MP, at an event held near the company's Glasgow headquarters. Representatives from the successful businesses signed SP Energy Networks' Delivery Charter, formalising their commitment to creating green jobs, fostering positive community impact, and ensuring a safe working environment.

Nicola Connelly, CEO of SP Energy Networks, highlighted the strategic importance of these partnerships: "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 benefiting central and southern Scotland and its infrastructure for decades to come. This is 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."

Energy Minister, Michael Shanks MP, praised the initiative: "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SP Energy Networks partnerships take us a step closer to reaching clean power by 2030, in modernising the country's outdated network to get more of clean power generated in Scotland to homes and businesses across the country.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 awarded contracts encompass a broad spectrum of critical infrastructure development, including new and upgraded high-voltage substations, overhead line construction, and comprehensive design, engineering, construction, and electrical works. Initially, these strategic partnerships will run for five years, with an option for a five-year extension, providing long-term certainty for suppliers. Notably, 17 of the 19 successful suppliers are based within the UK.

Among the key appointments, Morgan Sindall Infrastructure stands out as the sole contractor for both substation and overhead lines on the vital Denny to Wishaw project. A joint office for this project is scheduled to open at Eurocentral in the Autumn.

Peter Kirk, Managing Director, Energy, at Morgan Sindall Infrastructure, commented: "We're proud to support the UK energy network's biggest upgrade in a generation, and to be part of SP Energy Networks' Delivery Charter. Projects like the Denny to Wishaw Network Optimisation (DWNO) will improve resilience and energy security, boost capacity to meet future demand, and connect Scotland to greener, renewable energy. In upgrading the transmission network, we will be able to bring skills and employment to the central belt, and leave a lasting legacy in the local communities."

This announcement follows ScottishPower's recent commitment to more than double its UK investment to £24 billion by 2028, with two-thirds of this substantial sum earmarked for electricity networks. SP Energy Networks has also submitted its five-year business plan for 2026–2031 to Ofgem, further solidifying its integral role in achieving the UK Government's Clean Power 2030 ambition.
