Transmission and Distribution

We work closely with local, national and international electricity network owners to provide technical engineering solutions that cover every aspect of the electricity grid. From overhead lines to cabling, substations and distribution networks, our team is dedicated to ensuring reliable and safe power for millions of homes and businesses.

We offer a wide range of services, from initial scoping and feasibility studies all the way through design, construction and ongoing maintenance. Our goal is to meet the unique needs of each project and provide flexible solutions that keep the power flowing smoothly, safely and reliably to millions of homes and business. Our adaptable resources and innovative approaches have played a pivotal role in some of the world's most ambitious transmission and distribution projects, including ElecLink, a remarkable 65km electricity cable between France and Great Britain through the Channel Tunnel. This groundbreaking interconnector significantly enhances the energy capacity and security of both nations.

We provide a comprehensive range of services covering all transmission and distribution needs. Our expertise extends from Low Voltage (LV) to Extra High Voltage (EHV) cabling, with a particular emphasis on 132kV to 400kV projects. Watch our short video to learn how we have used innovative solutions to lay a 33kv cable.

Our dedicated teams are experts in the construction, refurbishment and maintenance of overhead transmission lines. We understand the vital role that a modern power network plays in our lives. That's why we are committed to connecting renewable energy resources and delivering sustainable electricity infrastructure that ensures the safe, reliable and cost-effective supply of power.

We take pride in guiding and supporting our customers throughout their decision-making process. Our goal is to support them in making informed choices and executing their investment plans to the highest standards. By doing so, we contribute to the development of a resilient and efficient energy landscape that benefits both our clients and the environment.

We are proud to be one of the leading suppliers of high voltage substations in the UK, specialising in control and protection systems. Our dedicated teams, including our in-house designers and programme managers, work closely together to handle every aspect of substation manufacturing, installation, testing and commissioning. Our expertise includes both extra high voltage (EHV) and high voltage (HV) substations, along with all the necessary civil work.

Our capability includes the design and manufacture of electrical switchgear and power distribution substations. We also provide automation products from a range of reputable manufacturers, ensuring we can meet the unique requirements of bespoke projects.

Our expertise extends beyond product manufacturing. We undertake various projects using different contract forms, including Engineering, Procurement and Construction (EPC). Within these projects, we deliver a wide range of essential components, such as control and protection panels, substation computer control systems and robust support structures made from both aluminium and steel.

We understand the importance of delivering high-quality solutions that meet stringent standards. That's why we strive to provide comprehensive services and reliable products to our customers, ensuring their projects are executed with precision and efficiency.

Control and protection are essential for reliable power transmission networks. Our expert teams work across substations, power stations, and wind farms, specifying, engineering, building, testing and commissioning these vital systems. We prioritise safety, efficiency and seamless integration to deliver high-quality solutions for our customers.

Our team of skilled experts excels at seamlessly integrating equipment and systems, creating efficient and reliable automated computer control and monitoring schemes.
 
When it comes to commissioning, we follow a comprehensive approach that encompasses all power and control interfaces. This ensures that the delivered system is fully operational and installed precisely to specifications, providing customers with a dependable and high-performing system that seamlessly integrates into operations.

We offer a fully integrated solution for distribution substations. 

Our in-house design and manufacturing capabilities allow us to assemble, fit-out, and test substations at our own premises. This off-site manufacturing approach significantly reduces costs and installation time, ensuring efficient and cost-effective solutions.

We specialise in the design and manufacture of electrical switchgear and power distribution substations. 

We offer a comprehensive solution for fibre optic assets, taking care of everything from installation to repair and maintenance. Our goal is to assist our customers in effectively managing their network assets in a cost efficient and sustainable manner. 

We have extensive experience of working with both onshore and offshore high voltage (HV) and extra high voltage (EHV) assets. Our range of services includes long-term operation and maintenance contracts, installation engineering, procurement and responsive repair frameworks.

Our dedicated in-house teams are committed to delivering fully integrated solutions for our customers. From procurement to engineering, construction and contract management, we take care of every aspect of the project.

We take pride in operating and maintaining transmission assets on behalf of asset owners. Our annual maintenance contracts cover substations, converters, transmission cables and general repairs, ensuring the reliable and smooth operation of the assets.
 
Our integrated asset management services include: 

  • Sub-sea surveys 
  • Condition assessments 
  • Planned maintenance 
  • Inspections 
  • Fault identification 
  • Monitoring 

We also provide the specialist skills needed to construct and lay cables on and off-shore. Our specialisms include near-shore works such as horizontal directional drilling and all aspects of cable jointing and terminations.
