Transmission and distribution

Transmission and distribution

Balfour Beatty’s power transmission and distribution teams work with regional, national and international electricity network owners and operators to provide technical engineering solutions.

We deliver a range of services to support a reliable and safe supply of power to millions of homes and businesses around the world. Our experience and expertise covers the whole electricity grid, including overhead lines, cable tunnels and distribution networks.

From scoping and feasibility, to design, construction and on-going maintenance, our flexible resources and innovations support customers in the development of some of the world’s most ambitious power transmission and distribution projects.

Cabling

We are one of only a few specialist providers with the ability to operate across the transmission and distribution spectrum from Low Voltage (LV) to Extra High Voltage (EHV), with a special focus on 132kV to 400kV.

We provide services that include the ability to assess scheme feasibility and scope the detailed requirements of a contract in advance of design and construction.

Fibre optic solutions

Reliable communications that support quality of life and enable economic prosperity will become ever more critical. Scalable communications mediums will be vital as the need to reduce emissions caused by transport increases year on year.

Our ability to provide an end to end solution for fibre optic assets from installation to repair and maintenance can be a major benefit to organisations seeking to manage their network assets in a cost efficient and sustainable manner.

Offshore

Covering both the onshore and offshore high voltage (HV) and extra high voltage (EHV) assets we deliver across long-term operation and maintenance contracts, installation EPC and responsive repair frameworks. Our approach is built on in-house engineering and project management expertise, coupled with specialist supply chain capabilities to deliver a fully integrated solution from engineering to procurement, and construction through to management.

With a long heritage in power transmission and distribution delivery, we operate and maintain transmission assets on behalf of asset owners, working under annual maintenance contracts covering substations, converters and transmission cables and general repairs and faults.

We also provide integrated asset management services, including sub-sea surveys, condition assessments, planned maintenance and inspections, fault identification and monitoring.

For installation projects we provide the specialist skills needed to construct and lay cables on and offshore including near-shore works such as horizontal directional drilling and undertaking all aspects of cable jointing and terminations.

We have unrivalled access to HV and EHV jointers through our leading presence in the European HV and EHV transmission and distribution market.

Overhead lines

Our customers recognise the vital importance of a modernised power network; creating opportunities for harnessing renewable energy resources and delivering sustainable electricity supply to millions of consumers safely, reliably and economically.

Innovation is changing the way in which electricity is generated and where it is created. ‘Smart grids’ that anticipate future changes and provide network operators with increased flexibility will define investment strategies.

The construction, refurbishment and maintenance of overhead transmission lines is benefiting from our excellence in engineering innovation to radically improve safety and reduce time spent onsite.

Our role, as one of the world’s leaders in overhead line transmission design, construction and maintenance, is to help our customers make the right decisions and deliver their investment plans to the highest standard.

Substations

With specialist expertise in control and protection systems, our substations team is one of the leading high voltage substation suppliers in the UK. Supported by in-house design and programme management expertise, we manufacture, install, test and commission extra high voltage (EHV) and high voltage (HV) substations, including all associated civil work.

As a specialist substation systems integrator, we have the flexibility to offer switchgear and automation products from a range of manufacturers, supporting bespoke project requirements.

We deliver a range of projects under EPC and other contract forms, including control and protection panels, substation computer control systems, and aluminium & steel switchgear support structures, continually investing and developing the engineering expertise of our teams.

Switchgear manufacture

We specialise in the design and manufacture of electrical switchgear and power distribution substations. Click here for more information.

Control and protection

Control and protection solutions are a key element in providing safe, efficient and reliable power transmission networks. Tailoring our solutions to customer’s individual needs, we work across a number of applications, including transmission substations, distribution substations, power stations and wind farms. Our approach is supported by our engineering and design teams who specify, engineer, build and test through to final commissioning on-site.

Computer control systems

Our teams provide the in-house expertise needed to integrate equipment and systems seamlessly, assuring the delivery of efficient and reliable automated computer control and monitoring schemes.

Our approach is supported by our engineering and design teams who specify, engineer, build and test through to final commissioning on site.

Commissioning is an integrated process, including all power/control interfaces, ensuring a full operational system is delivered and installed to specification.

Outdoor package substations

We offer a fully integrated solution for distribution substations. Designed in-house, with assembly, fit-out and testing at our own premises, and installation and commissioning on site, our off-site manufacturing techniques deliver significant reductions in cost and installation time.

Switchgear support structures

We offer a range of aluminium and steel switchgear support structures suitable for outdoor air insulated switchgear applications in transmission substations, distribution substations, power stations and wind farms.
