The power to deliver high speed rail

UKPNS The Power To Deliver High Speed Rail

As new rolling stock enters service more energy-hungry trains running at increased frequency is placing pressure on existing electrical infrastructure.

This demand, alongside additional customer conveniences like air conditioning, longer trains, and more frequent services, is placing pressure on existing electricity infrastructure.

Five key characteristics to look for in your long term strategic energy infrastructure partner are safety, innovation, sustainability, diversity and inclusion, and collaboration. These characteristics are crucial to ensure successful projects that will guarantee your high speed rail network’s electricity infrastructure is up to the standard required for the next decade and beyond.



High speed rail projects moving off the drawing board and into reality have the opportunity to be the safest in the UK’s history. This ambition can only be realised through an unrelenting focus on safety, innovative processes and training programmes for colleagues and clients, and a culture where safety always comes first.

We manage the associated risks of working with electricity and deliver safely for our clients in the most complex and challenging environments every day. Whilst working on Europe’s busiest runways, trackside on the UK’s fastest mainline railway, at nuclear sites, and military facilities, we have achieved an unprecedented safety record.



Adopting an innovative approach to projects is crucial to minimising risk, future proofing solutions, and delivering a resilient system. As well as adopting the latest technology, it’s critical that your partner should be able to adapt when unforeseen challenges arise on projects and provide innovative solutions to keep the project on track.

Our innovative work on the Great Western Electrification Project won Innovation of the Year at the National Rail Awards 2018 for our implementation of a ground breaking Rationalised Autotransformer System. The system delivers significant cost savings and better reliability for our client compared to other systems installed in the UK. We also topped the Sustainable Construction category at National Rail’s Western Region Sustainability Awards in 2017. Polyfibre-reinforced concrete was used in place of traditional steel reinforcement for construction of load bearing concrete structures. This innovation resulted in a reduction of 42 tonnes of reinforcing steel going to site and reduction of embodied carbon by 18,000kg CO2 equivalent.



Sustainable solutions have a positive effect on the environment, economy, and people. These ‘triple bottom line’ benefits can have greatest impact through major infrastructure projects but any effective energy partner must develop and preserve objectives which:

  • Protect and improve our natural environment while reducing carbon emissions
  • Invest in local economies and communities
  • Employ locally during construction and ongoing operations
  • Deliver the work safely for our communities and employees
  • Enable the future by designing systems that stand the test of time

We look for every opportunity to make a positive sustainable impact for our clients. We are currently delivering energy cost reductions for our clients through improving the efficiency of its assets, by co-locating solar PV with substations. Recently, the first electric vehicles and charge points have also been introduced into our fleet to improve air quality for future generations. These have been introduced at our Heathrow, Gatwick, and Stansted Airport depots, and electric vehicle charge points at our London City Airport depot.


Diversity and Inclusion

Embracing diversity and inclusion as a strategic imperative is critical for any organisation that strives for high performance. Supporting diversity and promoting inclusion within workplaces is about valuing the individual and what they bring to their role. Fostering an environment where everyone feels able to participate and achieve their potential enables organisations to effectively increase their employee engagement and realise an increase in productivity.

Our ongoing commitment to diversity and inclusiveness is demonstrated by our National Equality Standard accreditation. We are one of only a small number of UK companies to achieve this benchmarked standard for creating a diverse and inclusive workplace. In 2018, 2019 and 2020, we were also named in ‘The Sunday Times 25 Best Big Companies To Work For’ list.



Any long term strategic partner must be experienced at collaborating with multiple partners when delivering complex and large scale projects. The more partners involved in a project the greater the complications that can arise.

We are committed to establishing long-lasting, open and trusting relationships. We are accredited in the Collaborative Business Relationship Management System ISO 44001:2017 standard to help us deliver successful collaborative relationships with appropriate clients, delivery partners and suppliers. Through our collaborative approach, we contribute to the creation of value oriented enterprising teams that deliver high performing infrastructure.

For High Speed 1's power assets, the result has been a considerable cost-saving whilst still delivering network availability over 99.99% for more than 10 years continuously. As its strategic energy infrastructure partner, we have made a significant contribution to the success of High Speed 1’s reputation as the most reliable railway in Europe.



To be effective, your long term strategic energy infrastructure partner needs to demonstrate these five crucial characteristics – safety, innovation, sustainability, diversity and inclusion, and collaboration. Our business is built around these characteristics. Our investment is focussed on these characteristics. Our greatest successes are where we have brought these characteristics to life in our delivery with our clients. We have delivered for our clients for more than 50 years and our portfolio includes High Speed 1, Network Rail, London Underground, Docklands Light Railway, and EDF (Hinkley Point C). We also deliver for leading UK airports, Heathrow, Gatwick, Luton, Stansted and London City.
