IFA2 is a 1,000 MW high voltage direct current (HVDC) electrical interconnector currently under construction between the British and French transmission systems. It will be the second link to France that National Grid has developed with RTE.

Why do we need interconnectors?

An interconnector allows countries to exchange power, helping to ensure safe, secure and affordable energy supplies. They are the heart of the transition to a smarter energy system and integral to delivering a more flexible energy system for consumers.

Why do we need IFA2?

IFA2 will provide the capability to export or import 1,000MW of power. This brings three important benefits for our national energy requirements:

Affordability:

By giving Great Britain access to the European electricity market, IFA2 should help create downward pressure on wholesale electricity prices. We estimate that each 1,000MW of new interconnector capacity has the potential to reduce wholesale prices in Great Britain by up to 2%.

Security of supply:

Consumers throughout Europe use electricity in various ways at different times of the day, and interconnection allows electricity to be moved to where it is needed. This is particularly important at times of ‘system stress’, such as a combination of cold weather and unexpected power station shutdowns.

Sustainability:

Interconnectors allow countries to look beyond their borders and use renewable energy more efficiently. When it is sunny and windy in Great Britain, for example, where lots of power is generated, electricity can be moved quickly to a country where it’s needed. When British conditions are less favourable, power can be imported from Europe.
