National Grid Announces New Supply Chain Partners

National Grid launches pioneering ‘enterprise model’ as response to UK supply chain and skills shortage, announcing the first seven supply chain partners to form the Great Grid Partnership.

The Partnership, which will initially focus on the network design and construction work required by the end of the decade for nine major infrastructure projects across England and Wales, forms part of a £9bn supply chain framework which will also support infrastructure projects beyond 2030.


The Partnership will support supply chain capacity and foster collaboration across best practice and skills, delivering benefits for consumers and the wider UK economy. This investment further underlines National Grid’s commitment to the people, jobs and skills required to help deliver the energy transition.

Investment in the UK’s electricity network industry will contribute an average of £18.4bn to GDP and support around 220,000 jobs each year between 2024 and 2035. [1]


In a major boost to the UK supply chain, National Grid has launched the Great Grid Partnership. The company, which sits at the heart of the UK energy transition, has named the seven partners who will support the delivery of an initial nine Accelerated Strategic Transmission Investment (ASTI) projects.

The ASTI projects form a key part of The Great Grid Upgrade, which is building the significant new electricity network infrastructure required to reduce the UK’s reliance on fossil fuels by connecting 50GW of offshore wind by 2030.

This new ‘enterprise model’ is a collaborative partnership, bringing together National Grid’s supply chain partners. Two design and consenting service partners [AECOM Arup (JV); WSP], and five construction partners [Laing O’Rourke; Morgan Sindall Infrastructure; Morrison Energy Services; Murphy; Omexom / Taylor Woodrow (OTW)] are joining National Grid in the newly formed Great Grid Partnership.

Designed to speed up the delivery of much needed national electricity infrastructure by taking a fresh approach to UK supply chain and skills issues. The partnership aims to coordinate the planning and execution of projects, allowing each supplier and National Grid to pool their resources, skills, insights, and experience to deliver faster and more economically – driving value for money and benefits for both consumers and local communities.

By creating these long-term strategic contractual relationships, our partners will work collectively as an enterprise to drive value and innovation and secure delivery. Once established, this pioneering model will also deliver significant opportunities and benefits beyond the initial ASTI framework.

The partnership comes as the demand for products, services and skills continues to rise on a global scale as countries ramp up investment in the energy transition. It represents a huge challenge but also a great opportunity if industry works together to take advantage of the opportunity.

Carl Trowell, President, Strategic Infrastructure, National Grid said:

 “This announcement is another significant and exciting milestone in the delivery of The Great Grid Upgrade – the largest overhaul of the electricity grid in decades. The scale and pace of this upgrade requires us to unite as an industry and to think and act differently."

“This Great Grid Partnership is a ground-breaking initiative from National Grid that places our supply chain partners at the heart of our infrastructure upgrade programme. All our chosen partners have an established history of successful collaboration in delivering major projects and enabling innovation to thrive."

“By sharing best practice and collaborating across nine of our critical major ASTI infrastructure projects, we will set the gold-standard for future infrastructure projects in terms of driving innovation, shoring up capacity across the skills base, operating responsibly and sustainably and ultimately in getting the best value for consumers.”
