GE Vernova, MYTILINEOS bag £1bn contract for UK’s first high-capacity subsea link
In a major leap forward for the United Kingdom’s renewable energy efforts, GE Vernova’s Grid Solutions business and MYTILINEOS Energy & Metals have announced their selection for a £1 billion contract by National Grid Electricity Transmission and SP Transmission, part of SP Energy Networks (SPEN). This contract involves the creation of the UK’s first high-capacity east coast subsea link.
EGL1 Project: A Milestone in Renewable Energy Transmission
The GE Vernova–MYTILINEOS consortium will supply and construct two High-Voltage Direct Current (HVDC) converter stations for the Eastern Green Link 1 (EGL1) project. EGL1, a joint venture between National Grid Electricity Transmission and SP Transmission, is set to oversee the construction of a 525kV, 2GW bipole Voltage-Sourced Converter (VSC) and HVDC subsea transmission cable. Spanning from Torness in East Lothian, Scotland to Hawthorn Pit in County Durham, England, this project is pivotal in transmitting renewable green energy to power over two million homes in the UK.
GE Vernova and MYTILINEOS Awarded Landmark Contract for UK’s First High-Capacity Subsea Link
Advanced HVDC Technology Integration
The HVDC cable system, approximately 190km in length, represents the latest in HVDC technology. VSC technology provides an efficient and reliable means of transmitting large amounts of power over long distances subsea. GE Vernova, as the consortium leader, alongside MYTILINEOS, will undertake the engineering works and technology provision for the two VSC HVDC converter stations. These stations are essential in converting direct current to alternating current, thereby enabling the transmission of electricity into the onshore network.
Timeline and Project Details
The design phase is scheduled to begin in January 2024, with construction set to commence in 2025. This project marks a critical step in the UK’s decarbonization and energy security efforts. Philippe Piron, President and CEO of GE Vernova’s Grid Solutions, expressed honor in being awarded the HVDC contract for EGL1 and recognized the project’s significance in utilizing GE Vernova’s advanced HVDC technology.
MYTILINEOS’ Contribution and Expertise
Evangelos Mytilineos, Chairman & CEO of MYTILINEOS, shared his satisfaction with the collaboration and emphasized MYTILINEOS’ long-standing expertise in managing and building large and complex grid projects. MYTILINEOS will handle engineering, procurement, construction of civil works, balance of plant, and equipment installation. With a notable track record in HV and UHV transmission projects, MYTILINEOS stands as a reliable partner for transmission and distribution network owners globally.
Impact on Energy Transition and Grid Stability
This project underlines the crucial role of subsea links in the context of the energy transition. Such links facilitate the development and integration of renewable energy sources, improve grid stability, and contribute to a more sustainable and diversified energy mix. EGL1 is a key component in supporting the UK’s efforts for decarbonization and ensuring security of supply.
In summary, the EGL1 project, led by the GE Vernova–MYTILINEOS consortium, is set to revolutionize the UK’s energy landscape. By harnessing advanced HVDC technology, this project is a testament to the collaborative efforts in achieving a sustainable and secure energy future.
