About IFA2

IFA2 will connect the electricity systems of Great Britain and France using high voltage subsea cables from Normandy in France to Hampshire in Great Britain.

Enhancing Great Britain’s energy connection to France will bring a number of benefits, including:

  • Helping to reduce the cost of electricity for homes and businesses in Great Britain.
  • Increasing security of electricity supplies for both countries.
  • Providing opportunities for shared use of renewable energy – helping both countries to meet domestic and international renewable and climate change targets.

IFA2 aims to be operational by 2020.


Project partners

The project partners, National Grid and Réseau de Transport d'Electricité (RTE), already work together on a daily basis managing the existing IFA link between Folkestone and Calais.

National Grid              

National Grid is a major UK company which owns and manages gas and electricity infrastructure in the UK and in the northeastern US.

In the UK, National Grid runs the systems that deliver gas and electricity across the entire country and provides power directly to millions of customers. National Grid holds a vital position at the centre of the energy system, joining everything up.

National Grid already co-owns and operates electricity interconnectors with France (known as IFA - Interconnexion France Angleterre), and the Netherlands (known as BritNed). To meet changing energy needs, many more interconnectors are being developed all around the country to increase the connections between Great Britain's electricity transmission system and other countries' networks. National Grid has recently announced investments in new interconnectors to Belgium (known as NemoLink) and to Norway (known as North Sea Link).

National Grid IFA2 Ltd is the company that National Grid has formed to develop and bring forward the IFA2 project and is legally separate from other companies within National Grid. In November 2014, National Grid IFA2 Ltd was granted an electricity interconnector licence by the energy regulator Ofgem.


RTE is the electricity transmission system owner and operator in France. Founded on July 1st 2000, RTE was given the task of maintaining, operating and developing the transmission system on an independent basis.           

Projects of common interest

The European Commission has identified IFA2 as a Project of Common Interest (PCI). This means it should:

  • Deliver significant benefits for at least two European Member States
  • Further support market integration and competition
  • Enhance security of energy supply
  • Contribute to reducing CO2 emissions

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

A link to the TEN-E Regulations is provided below.
