The works in Horsey require the installation and removal of temporary masts, two new angle towers and the building of two cable sealing end compounds, where overhead electricity lines connect onto the new section of underground cables.
The two new pylons replace two original gentle giants - 91m high pylons built 90 years ago - and highlight the remarkable evolution of engineering techniques and sea transportation between the 1930s and 2020s.
The original gentle giants
Built in the 1930s, the two original pylons were constructed panel by panel and lifted up using a lifting device called a gin pole. Workers would have used a series of pulleys and guide wires to lift pylons into place.
The company today published its chosen location options for the interconnector’s landfall, cable route, and convertor station, following its second public consultation held last autumn.
1. Understanding Britain’s complex connections conundrum
Britain’s connections process is in need of reform – and we’ve been working hard with government, Ofgem and industry to deliver it. That means understanding and addressing the complex interacting issues at play, so the right changes can be made.

EGL2 will see the creation of a 525kV, 2GW HVDC subsea transmission cable from Peterhead in Scotland to Drax in England.
These guidelines will apply to both the build of new electricity transmission assets, as well as developer specific user assets, and must be considered as part of any project plans.
The hall has served as a community hub since its opening in 1965 but in 2019 the lease on the hall was set to run out galvanising the local community which raised £100,000 to prevent the building from closing down.
National Grid’s first Community Grant provided £20,000 and, along with other generous supporters, allowed the hall’s trustees to extend the lease and continue providing a valuable space for the local community to enjoy.
A young girl who has a special interest in pylons – also known as electric towers – recently had her dreams come true when she was invited to visit National Grid’s high voltage Penwortham substation in Preston.
4-year-old Lucy, from Blackpool, recently went viral on TikTok when her mum posted a video capturing her daughter’s special interest in electric towers on the social media platform.
The Hinkley Connection project stretches 57km from Bridgwater to Avonmouth and will connect six million homes and businesses to new sources of low carbon, homegrown energy, including from Hinkley Point C.
Construction began in 2018 and is set for completion in 2025. The four million hours worked to date by teams from National Grid and its 12 specialist contractors have been put to good use.
Key achievements include:
Each transformer, weighing in at 178-tonnes – the equivalent of 30 African elephants – will make its way from Tilbury Docks on Sunday 11 and Sunday 18 February.
Transformers play a vital role in helping to ensure the UK continues to enjoy safe and reliable energy supplies. They’re needed here to maintain secure electricity supplies to the surrounding area and meet increased demand, as part of the Biggleswade substation construction.
