SSEN Transmission, the Scottish grid operator, has launched a new procurement process aimed at identifying contractors to support key elements of substation development as part of its RIIO-T3 and networks renewals investment programme. This initiative is designed to enhance the transmission system’s capacity to accommodate increased clean energy generation.
The procurement framework, now open for pre-qualification, introduces a new maximum value threshold for moderate substation works, which has increased from £20 million to £40 million. This change will allow both new and existing contractors to submit applications for critical substation work, as well as associated subsidiary overhead line and underground cable projects.
The estimated combined value of the framework agreements available is up to £1.4 billion. Contractors interested in participating are invited to complete the Pre-Qualification Questionnaire via the Achilles UVDB platform.
Kevin Smith, Head of Supply Chain at SSEN Transmission, emphasized the importance of securing the right contractors for the critical infrastructure required to meet energy security and clean power goals. “As we prepare to deliver the critical national infrastructure across the north of Scotland that is required for the delivery of energy security and clean power targets, it is crucial that we secure the supply chain that is needed – and the launch of our latest procurement process today marks a significant step forward in doing that,” Smith said.
Smith also noted that SSEN Transmission has already secured several key supply chain partners, including local companies, and is now seeking additional delivery partners for substation work, with contract values of up to £40 million. “As we advance into the delivery phase of our ‘Pathway to 2030’ investment programme, and anticipate an exciting investment portfolio beyond, introducing new capacity and developing a diverse supply chain are key priorities for us,” he added.
The procurement process is part of a broader £22 billion investment plan by SSEN Transmission between 2026 and 2031 to support Scotland’s and the UK’s energy security and net-zero objectives. This investment will include the development of new substations and upgrades to existing ones, potentially supporting up to 8,400 jobs in the north of Scotland.
The application window for the procurement process is open for the next five weeks.
