The ETP framework is designed to facilitate the transition to cleaner energy sources.
The framework, part of the broader RIIO-T3 investment plan, allocates £8 billion for 130 substation projects through 2030. This aligns with National Grid’s strategy to invest up to £35 billion in upgrading and expanding the transmission network. The ETP incentivizes suppliers based on performance and their ability to expand operational capacity, fostering local skills development and strengthening the domestic supply chain.
In July 2025, National Grid named regional delivery partners, including Balfour Beatty (northeast), Morgan Sindall Infrastructure (northwest), Murphy (southwest, London, and southeast), M Group Energy (southwest region two), and OTW (central west). These partners gain priority access to substation projects in their regions, enabling long-term planning and capability growth. An initial £1.3 billion was allocated for exclusive projects, with contracts to be finalized later. Linxon and Burns & McDonnell were appointed as national partners to support additional substation initiatives.
UK Energy Minister Michael Shanks stated: “The clean energy transition is the economic opportunity of the 21st century, with the potential to revitalise our industrial heartlands with skilled jobs and economic growth. This £8bn partnership from National Grid is proof of that – providing 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’s electricity transmission president, Alice Delahunty, added: “Our Electricity Transmission Partnership marks a bold shift in how we deliver vital electricity infrastructure. By adopting a regional, long-term approach, we’re giving our supply chain the certainty to invest in people, skills and innovation. It’s a key step in turning our RIIO-T3 investment ambitions into action and building a resilient grid to support Britain’s clean energy future.”
The ETP is part of National Grid’s broader efforts to enhance its supply chain, alongside initiatives like the Great Grid Partnership and a new high-voltage direct current framework. These programs aim to boost capacity and resilience across infrastructure projects. The ETP model may expand to include other network infrastructure, ensuring a unified approach to strengthening the transmission network in England and Wales.
