Hitachi Energy Chosen for UK's Longest HVDC Link

Hitachi Energy, a renowned global technology leader committed to shaping a sustainable energy future, has exciting news to share. They proudly announce their selection as the preferred technology provider for SSEN Transmission and National Grid.

This prestigious designation allows Hitachi Energy to supply two high-voltage direct current (HVDC) converter stations, which will interconnect the power grids of Scotland and England.

The ongoing energy transition demands collaborative efforts and cutting-edge technologies. By appointing Hitachi Energy as their preferred technology provider, SSEN Transmission and National Grid ensure access to top-notch technology and future production capacity in a rapidly expanding market.

This strategic move also empowers Hitachi Energy to invest in new production capabilities and undertake large-scale recruitment drives, further fostering collaboration, standardisation of solutions, and synergies between projects.

In this era of integrating renewables into the energy mix, grid resilience, stability, and flexibility are paramount. Hitachi Energy's remarkable innovations, particularly their voltage sourced converter (VSC) power electronics and control and protection (MACH™)1 technologies, meet these critical requirements, proving instrumental in various landmark grid integration projects.

One remarkable endeavour, the Eastern Green Link 2, stands out as the longest HVDC link in the UK. Comprising two 525-kilovolt (kV) bipole VSC converter stations connected by 440 kilometres of subsea cable and 70 kilometres of underground cable, this impressive project will efficiently supply 2,000 megawatts (MW) of electricity—enough to power approximately two million UK homes.

The link is set to bolster power transmission in the northern UK and facilitate the integration of new renewable electricity generation in Scotland, aligning with the UK's ambitious Net Zero Strategy. With the potential for up to 11,000 MW of offshore wind capacity in Scottish waters by 2030, HVDC transmission plays a crucial role in bringing this abundant renewable power to communities across the country.

Niklas Persson, Managing Director at Hitachi Energy's Grid Integration business, emphasises the significance of electricity as the backbone of the entire energy system to achieve the UK's Net Zero targets. Hitachi Energy's pioneering HVDC technology ensures that electricity reliably and efficiently reaches its intended destinations.

The collaborative efforts with BAM, a prominent construction company specialising in sustainable buildings and infrastructure, are a crucial aspect of the project. Together, they will deliver the civil and installation scope for the Eastern Green Link 2, leveraging their core competencies to provide an unparalleled solution.

Hitachi Energy boasts an impressive legacy, having pioneered commercial HVDC technology nearly 70 years ago and delivering more than half of the world's HVDC projects. Their dedication to innovation and sustainability continues to shape the energy landscape, paving the way for a greener, more resilient future.

As the project progresses, excitement builds for the positive impact it will have on the UK's journey towards a net-zero future and enhanced energy security. With Hitachi Energy and its esteemed partners at the helm, the future of sustainable energy integration looks brighter than ever.
