- The frameworks cover operational technology cybersecurity, substation design, and digital services.
- The work supports network resilience, renewable integration, and digital transformation across the north of Scotland transmission system.
Jacobs has been selected by SSEN Transmission for multiple strategic frameworks supporting the modernisation and security of the north of Scotland’s electricity transmission network.
The frameworks have a combined potential value of more than $1bn and cover operational technology cybersecurity, substation design, and digital services. Jacobs, including PA Consulting, has secured positions on SSEN’s Digital and OT Cyber Security frameworks, with the work supporting grid resilience and renewable integration.
The awards sit within a transmission system undergoing rapid expansion. The north of Scotland is central to the UK’s renewable generation pipeline, particularly offshore wind, onshore wind, hydro, and future low-carbon infrastructure. Moving that power to demand centres requires investment in substations, overhead lines, underground and subsea cables, converter stations, control systems, and digital network management.
Under the Operational Technology framework, Jacobs will support the design, deployment, and assurance of secure OT environments across substations. The work includes cyber-by-design principles, network segmentation, and real-time threat monitoring alongside infrastructure and control systems. As transmission networks rely more heavily on connected protection, monitoring, and automation systems, those disciplines are becoming part of the engineering baseline.
The Digital Services framework will use AI-enabled digital and data solutions to support more efficient operation across SSEN’s network. The work will support SSEN Transmission’s RIIO-T3 transformation programme, with a focus on asset management, network growth, decarbonisation, and the creation of a scalable digital backbone for the transmission system.
Substations, lines, and transformers are increasingly being specified as part of a digital operating environment rather than as isolated physical assets. Asset data, condition monitoring, cyber controls, remote diagnostics, network modelling, and operational analytics now sit alongside conventional electrical design.
Grid equipment and asset intelligence are moving closer together across the sector. Siemens Energy’s acquisition of Camlin Group brought monitoring and analytics capability deeper into grid technology portfolios, while Jacobs’ SSEN frameworks show the same direction from the engineering, advisory, and cybersecurity side of network delivery.
The cybersecurity element is particularly relevant for substations. OT environments are built around availability, safety, and deterministic control. They contain protection relays, remote terminal units, SCADA interfaces, communications equipment, control platforms, and engineering access points. Cybersecurity controls must protect the asset without disrupting the operational timing and reliability that grid protection systems require.
Network segmentation, secure remote access, monitoring, and incident response all have to be integrated carefully. Transmission operators cannot simply apply corporate IT practices to OT environments without adapting them to electrical system requirements. A secure substation still has to trip correctly, communicate reliably, and support field engineering work under operational pressure.
The frameworks also reflect the scale of Scotland’s grid expansion challenge. Renewable generation growth in the north of Scotland creates large power flows through areas with relatively low local demand. Transmission reinforcement is needed to move electricity south and to support new generation connections, while the pace of development adds pressure to design capacity, consenting, construction, and operations.
Digital asset management can help operators prioritise maintenance, understand condition, model constraints, and optimise investment over the asset lifecycle. It does not remove the need for physical reinforcement, but it can improve how existing and new assets are operated. For a transmission network with a large build programme, that lifecycle view is becoming more valuable.
The awards also align with the UK government’s energy sector cyber security strategy, which sets out a four-year roadmap as the sector moves toward Clean Power 2030. Transmission infrastructure sits at the centre of that programme because high-voltage networks connect major generation, interconnectors, storage, and large demand centres.
