The UK’s National Grid has launched the Electricity Transmission Partnership (ETP) framework, a £8bn ($10.5bn) initiative designed to bolster collaboration with suppliers for substation infrastructure development across England and Wales. This long-term cooperative model prioritizes regional partnerships, rewarding suppliers for performance and capacity expansion, with the aim of strengthening the UK supply chain and fostering local skill development.
The ETP is part of the broader RIIO-T3 investment plan, which earmarks up to £35bn for transmission network enhancements by 2030. This includes 130 substation construction and upgrade projects, with an initial £1.3bn allocated to exclusive projects in July 2025. Regional delivery partners, including Balfour Beatty, Morgan Sindall Infrastructure, Murphy, M Group Energy, and OTW, have been selected to lead these projects in their designated areas. National partners Linxon and Burns & McDonnell will support projects outside these regions.
UK Energy Minister Michael Shanks highlighted the economic potential of the clean energy transition, stating that the ETP “provides a boost for Britain’s supply chains, investing in the future of our highly skilled workforce and helping to deliver clean, homegrown power that we control.” National Grid electricity transmission president Alice Delahunty emphasized the strategic shift, noting that the ETP “gives our supply chain the certainty to invest in people, skills and innovation,” marking a key step in realizing RIIO-T3 ambitions and building a resilient grid for Britain’s clean energy future.
The ETP framework could reshape the energy sector by encouraging long-term investment and regional specialization. By providing suppliers with predictable, long-term contracts, the model may accelerate project timelines and reduce costs, ultimately benefiting consumers. The focus on local skill development and supply chain resilience could also mitigate risks associated with global supply chain disruptions. Moreover, the ETP’s success may pave the way for similar frameworks in other types of network infrastructure, fostering a more cohesive and robust transmission network.
However, challenges remain. The regional approach may lead to disparities in capacity and expertise across different areas, potentially requiring additional coordination and oversight. Additionally, the success of the ETP hinges on the performance and adaptability of the selected suppliers, as well as the effectiveness of the incentive structure. As the energy sector continues to evolve, the ETP framework may serve as a valuable case study in balancing regional development, supply chain resilience, and clean energy goals.
