Jones Bros powers UK-Germany energy link

The scheme, one of the world’s largest, will link the countries’ electricity networks through 725km of overland and subsea cabling, boosting energy security and integrating renewable energy sources across both nations.

“Interconnectors are key component to the global renewable energy market, and it is wonderful to play a part and utilise our civil engineering expertise for this new addition to the sector’s landscape,” said Gareth Jones, contract manager at Jones Bros.

The Ruthin-headquartered firm secured a multi-million-pound contract with Siemens Energy to deliver enabling works on the Isle of Grain in Kent.

This included constructing a 50,000m² development platform for a 1,400-megawatt converter station, alongside earthworks, drainage, attenuation ponds and a 600-metre ducting corridor for utilities.

Jones Bros collaborated with North Wales consultancy Caulmert, whose stabilisation design enabled the recycling of 40,000m³ of on-site material.

This sustainable approach reduced traffic movements and cut the need for importing or exporting soil.

A team of 25, including four apprentices, completed the works earlier this year, paving the way for Siemens Energy to commence major construction of the UK converter station’s concrete base and upcoming superstructure.

Established in the 1950s, Jones Bros is a leading name in marine civils, highways, flood defence and renewable energy projects.

The company has one of the UK’s largest plant fleets and has an award-winning apprenticeship scheme.
