New substation and transmission projects across the UK are set to move forward under a long-term infrastructure framework supporting the country’s energy transition and grid expansion.

Engineering firm Jacobs has been appointed to an eight-year strategic framework led by Murphy, covering a portfolio of projects within the Scottish and Southern Energy (SSE) network.

The programme will focus on delivering high-voltage infrastructure, including substations, grid connections, and transmission assets, which are critical to supporting the UK’s transition to a low-carbon energy system.

Substations are expected to play a central role in the framework, enabling the integration of renewable energy, managing increasing electricity demand, and ensuring system stability across the network.

According to Jacobs, the work will include high-voltage electrical design, engineering, and project assurance services, supporting the development and delivery of complex grid infrastructure projects.

The framework builds on ongoing substation development in the UK, including the Uxbridge Moor project in West London, where a new high-voltage substation is being constructed to connect new customers and address rising demand in the region.

That project includes both 400 kV and 132 kV substations, along with associated transmission infrastructure, highlighting the scale and technical complexity of modern grid developments.

Commenting on the framework, Jacobs’ Senior Vice President James Nash said:
“This framework is a testament to Jacobs' experience in delivering integrated design, engineering and project management solutions for our energy clients.”

He added:
“By continuing our relationship with Murphy supporting the development of substations, grid connections and renewable energy assets in Scotland, together we are directly contributing to the U.K.'s energy goals.”

From Murphy, Managing Director of Energy Liam Corr said:
“This framework is a major step forward in our mission to deliver sustainable energy infrastructure at scale.”

The UK is currently undergoing a major expansion of its electricity network, driven by rising demand from electrification, renewable energy integration, and data centre growth. Substations are a key enabler of this transition, acting as critical nodes that transform and distribute electricity across the grid.

Projects delivered under the framework are expected to contribute to the development of a more resilient, flexible, and future-ready power system, supporting the UK’s long-term net zero ambitions.
