Sustainable, low carbon energy
Our mission is to deliver sustainable, low carbon energy from Iceland to the UK through world-leading HVDC cable technology and energy infrastructure.
Providing up to 1.8GW of secure, affordable, low carbon energy to the UK
Providing a world-class manufacturing facility and c. 800 jobs
Providing Iceland with a significant increase to its GDP
ATLANTIC SUPERCONNECTION BEGAN DEVELOPING THE SUPERCONNECTION IN 2012 AND STARTED WORK ON PLANS FOR THE ADVANCED MANUFACTURING FACILITY IN 2016. SINCE THEN, ATLANTIC SUPERCONNECTION HAS PROVEN THAT THE SUPERCONNECTION IS TECHNICALLY FEASIBLE BEING ONE OF THE MOST ADVANCED SUBMARINE CABLE DEVELOPMENT PROJECTS IN THE WORLD AND IS READILY FINANCABLE
Ready to launch and complementary to the UK’s industrial, energy and climate change objectives, Atlantic SuperConnection will help the UK meet its growing demand for electricity and deliver security of supply.
• Delivering a c.1500km subsea High Voltage Direct Current (HVDC) cable from Iceland to the UK, providing up to 1.8GW of reliable, on-demand and baseload energy through clean hydroelectric and geothermal generation;
• Bringing sustainable, low carbon power to the UK, balancing intermittent power such as wind, all at a highly competitive strike price of around £55-£59/MWh; while
• Providing Iceland with increased grid security and significant economic benefits.
• ASC have procured a bilateral Connection Agreement with National Grid at Creyke Becke substation
THE ADVANCED MANUFACTURING FACILITY:
• Building a new purpose-built manufacturing and HVDC test facility providing advanced HVDC sub-sea manufacturing capability.
• Fostering world-leading technical and manufacturing capabilities; and
• Creating around 800 local jobs.
Atlantic SuperConnection provides a global manufacturing and IP opportunity, establishing itself in an evolving high-tech industry.
Production of HVDC cabling will enable Atlantic SuperConnection to develop and deliver future energy projects at home and abroad more competitively.
The development of the project is following a typical infrastructure capital investment program as set out below:
GLOBALLY RECOGNISED TECHNOLOGY BRINGING CLEAN ENERGY FROM ICELAND TO THE UK
The development of HVDC technology can be traced back as far as the 1880s. Modern HVDC transmission uses technology developed in Sweden and Germany in the 1930s with the first commercial installations in the Soviet Union and Sweden in the 1950s.
Today, HVDC is only used in point-to-point connections. The technology requires conversion to and from alternating current (“AC”) to HVDC at each end point via a voltage-source converter (VSC) station, as most onshore electricity grids are AC based. The conversion from AC to HVDC, and vice versa, is technically the most complicated part of the entire process.
Fortunately, our VSC stations will be located on land, making them easier to maintain. The type of VSC stations that we will use are well-established and have a smaller footprint and increased weather resistance.
For long distance bulk electrical power transmission, HVDC transmission is a superior technology to AC systems for a number of reasons:
• the efficiency of HVDC is only limited by the design of the cable (both conductor and insulator) and the operating temperature;
• HVDC transmission can achieve very low transmission losses, using generated electrical energy more efficiently and making it very economical;
• for submarine power cables, HVDC avoids the heavy currents required to charge and discharge the cable capacitance each cycle;
• HVDC allows asynchronous AC grids or AC grids with different frequencies to be connected, improving the stability and economy of each grid;
• the power flow through an HVDC cable is fully controllable in either direction and has inherent overload capability that can be actively used for peak supply. This facilitates effective stabilisation of a network against disturbances due to rapid changes in power; and
• HVDC (particularly XLPE) cables are unobtrusive and environmentally friendly.
THE ADVANCED MANUFACTURING FACILITY
The global market for HVDC cabling faces a major capacity challenge. Atlantic SuperConnection is developing a world class manufacturing HVDC cable facility to overcome this obstacle.
The Advanced Manufacturing Facility will be a joint venture with an existing and world leading HVDC subsea cable manufacturer.
This exciting development would provide:
• a new and strategically important high-tech manufacturing capability;
• a source of hundreds of jobs and strong economic growth and social benefit for the region; and
• import substitution and export opportunities
Atlantic SuperConnection is currently undertaking an assessment to find the best potential sites for the facility.
