AQUIND Interconnector

links the British and French electric power grids, helps improve security of supply and makes energy markets more efficient

2000 MW


16 TWh




AQUIND Interconnector is a new subsea and underground High Voltage Direct Current (HVDC) electric power transmission line between the South Coast of England and Normandy in France. By linking the British and French electric power grids it will help make energy markets more efficient, improve security of supply and allow for greater flexibility as power grids evolve to adapt to different sources of renewable energy and changes in demand trends such as, for example, the development of electric vehicles. AQUIND Interconnector was recognised as a candidate to obtain the PCI status (Project of Common Interest). With the capacity of 2,000 MW, AQUIND Interconnector will transmit approximately 16,000,000 MWh of electricity each year between the two connected countries, which is approximately 5% and 3% of the total consumption of Great Britain and France respectively, corresponding to the consumption of millions of households. The technology used by the interconnection will allow transmission of electricity in both directions. This will result in more efficient use of production capacities and better management of fluctuations in electricity consumption and production. The interconnector can also provide various services to the national system operators in both countries to ensure safe and reliable operation of national electricity transmission systems. Beyond that, the interconnector will deliver vital services to the national transmission system operators in both countries and provide a route for exporting surplus energy from Britain to France.

AQUIND Interconnector will use well-tested and reliable technology. Without overhead lines, its environmental and visual impact will be significantly lower than that of any power generation plant of comparable capacity.

AQUIND Interconnector is being developed without government subsidies. This will help ensure additional security and diversity of energy supply, promote energy market competition and enhance value for energy consumers.

*The actual utilisation rate of the interconnector depends on market conditions, limitations by national transmission system operators and other factors.
