First Structural Concrete Successfully Placed at Torness Converter Station

Cidon Construction has reached a significant milestone on the Eastern Green Link 1 (EGL1) project, successfully completing the first HVDC pile cap structural concrete pours at the new Torness Converter Station in East Lothian.

This marks the transition from enabling works and excavation into the main reinforced concrete foundation phase of one of the UK's most significant energy infrastructure projects.

Having mobilised to site in April 2026, the project team has made excellent progress in just two months. More than 1,500m³ of structural concrete has already been placed, blinding has been completed across all seven transformer bund bays, reinforcement has been installed to the first transformer bund slabs, and foundation works across the HVDC building footprint continue to progress at pace.

The Torness Converter Station forms part of the Eastern Green Link 1 (EGL1), a new 525kV high-voltage direct current (HVDC) subsea electricity transmission link connecting Torness in Scotland with Hawthorn Pit in North East England. Once operational, the link will be capable of transmitting enough renewable electricity to power around two million homes, strengthening the UK's electricity network and supporting the transition to net zero.

Safety, quality and collaboration have remained at the forefront throughout the project. This milestone reflects the commitment and professionalism of Cidon's site team, supply chain partners and the wider project team.

With transformer bund slabs, ground beams, below-ground services and subsidiary structures continuing over the coming months, the project is building real momentum.

Cidon is proud to be delivering the reinforced concrete works on behalf of METLEN, supporting a nationally significant infrastructure project that will strengthen the UK's energy resilience and help deliver cleaner, more sustainable electricity for generations to come.
