Amentum Selected for Projects to Upgrade and Protect the UK Energy Grid

Company to Deliver Digital and Cybersecurity Solutions to Boost Grid Resilience
CHANTILLY, Va., Sept. 1, 2026 – Amentum (NYSE: AMTM), a global leader in advanced engineering and technology solutions, has been selected for strategic positions on two significant UK energy frameworks awarded by Scottish and Southern Electricity Networks (SSEN) Transmission. Amentum will be the exclusive provider of high-end cybersecurity engineering services which aim to digitize and enhance the security of the United Kingdom’s energy grid.
SSEN Transmission is the owner and operator of the high voltage electricity transmission system for the north of Scotland, powering the clean energy transition and delivering a reliable, efficient network that creates lasting benefits for communities, the economy and the environment.
“SSEN Transmission is expanding the grid at a pace the UK’s energy security depends on, and that growth must be secure by design,” said Matthew Morgan, UK-based group director for Security, Systems and Integration at Amentum. “Our teams will protect critical assets, scale digital capability, and turn operational data into faster, better decisions. We are investing in our team in Scotland to deliver this work, backed by Amentum’s deep UK and international experience.”
Working from offices in Cardiff, Glasgow, London, and Warrington, Amentum will build upon existing security architecture work the company has performed for SSEN Transmission since 2022.
Under three-year agreements, Amentum will leverage its expertise in digital transformation, operational technology (OT), and renewable energy integration to support the UK’s energy transition goals.
“The Five Eyes cyber security agencies have recognized the impact of AI in accelerating the speed, scale and sophistication of cyber threats. Leveraging Amentum’s proven expertise in modernizing and securing critical digital infrastructure, we can support SSEN Transmission in addressing one of the most serious challenges of our time,” said Jennifer Walsmith, president of Intelligence & Cyber at Amentum. “We look forward to delivering the innovation and security needed to strengthen the UK’s energy future.”
