• Interconnectors - Iceland

  • Ice Link - in development

    National Grid Interconnector Holdings Limited, together with our project partners, are in the feasibility stage of developing an interconnector between Great Britain and Iceland*. The project is known as IceLink.  

    National Grid's project partners are Landsvirkjun, the state owned generator in Iceland, and Landsnet, the Icelandic Transmission System Operator (TSO).  

    A capacity of 1,000MW is being investigated, with desk studies ongoing to establish feasible converter sites, onshore and offshore High Voltage Direct Current (HVDC) cable routes, and landing points. It is expected that the landing points for the cable will be in Northern Scotland and South East Iceland. 

    The interconnector is expected to be around 1,000km in offshore cable length with an HVDC converter located in each country converting Direct Current (DC) to Alternating Current (AC) (and vice versa). It will connect the Icelandic and Great Britain electricity networks allowing electricity to be traded between the two countries. The cable will enable electricity to flow in both directions.

    The project is currently projected to be operational from 2027 and will make a positive contribution to European energy policy objectives helping Great Britain towards a minimum 10% interconnection target, facilitating renewables integration, reducing reliance on fossil fuels and resulting in socio-economic welfare benefits.  For example consumer electricity prices in GB should be reduced if it has access to increased imports of lower price energy from its neighbours and Iceland should derive greater value from its renewable resources.

    In October 2015, the UK and Icelandic governments agreed to create an energy task force to look at the benefits of the interconnector.  Following their work, the energy task force issued a statement on 12th July 2016 stating that their work was concluded and they would leave the decision to continue the work of the energy task force with their respective governments. Read the full energy task force statement

    The European Commission published its first list of Projects of Common Interest (PCI) in 2015 and IceLink was identified as one of 195 key energy infrastructure projects selected to have PCI status. A PCI is essential for completing the European internal energy market and for reaching the EU's energy policy objectives of affordable, secure and sustainable energy.

    To achieve PCI status, a project must have a significant impact on the energy markets and market integration of at least two EU countries. It must also boost competition on energy markets and boost the EU's energy security by diversifying sources, as well as contribute to the EU's climate and energy goals by integrating renewables.

    For more information on PCIs please visit the European Commission’s website.  Projects of common interest - European Commission

    PCIs are governed under Regulation (EU) No 347/2013 on guidelines for trans-European energy infrastructure, referred to as the TEN-E Regulations.

    *Iceland is one of the few countries in the world to generate all its energy from renewable sources such as water, geothermal energy and wind power.  Landsvirkjun is owned by the Icelandic state and generates and supplies two thirds of the electricity in Iceland.
