Renewables Sector

High voltage electrical engineering for wind, solar, hydro, waste to energy and other renewable projects

By 2050, the UK and Ireland’s renewables sector is expected to generate in excess of £40 billion a year. This notably growing market therefore looks set to reshape the nation’s energy agenda, and Smith Brothers has a significant role to play.

We’re the contractor of choice for two of the UK’s largest solar power developers – having already executed more than 100 of their projects, for instance – and we’ve worked on some of the biggest STOR schemes in the country.

We’ve secured the jobs because of our experience in this complex field, and our ability to supply safe, professional turnkey services.

There are virtually no wind power, solar energy, hydro, bio-generation, AD, waste to energy or STOR electrical infrastructure requirements that we cannot fulfil.

Our renewable energy services

Our highly-skilled high voltage electrical engineers can carry out the following services:

  • Execution of major electrical balance of plant contracts
  • Grid connections from 6.6kV to 132kV
  • Electrical design, supply and installation, switchgear, transformers, cable infrastructure, earth systems and SCADA cabling
  • All testing and commissioning
  • Installation of Feed In tariff (FIT) and auxiliary supply meters
  • Civil construction works.

A future of potential

As the windiest place in Europe, in 2008 the UK became the world’s biggest offshore wind power generator, before reaching the milestone capacity of 1GW in 2010. The UK’s solar power market has also reached a value of £1.6 billion a year, and the geothermal, biomass and waste to energy markets are continually advancing.

This is therefore one of the most exciting and evolving industries in the country. And when it comes to connecting these renewable energy infrastructures to enable the safe and reliable operation of the high voltage electricity network, many of the sector’s biggest names will turn to us.

Whether you are planning or currently working on a windfarm, solar power, biomass, AD, waste to energy or hydro power project, contact one of our renewable energy generation specialists to find out how we can help. Please call 0333 358 3653 or email
