The role of interconnectors in a net zero future

Interconnectors act like super-highways for clean energy. In many ways they are the perfect technology to integrate renewable energy and ensure a secure, affordable and sustainable transition to a cleaner energy system. 

By linking Britain to neighbouring countries, interconnectors can import cheaper clean energy when it is needed, while exporting excess power - so that both Britain and its neighbours have access to a broader and more flexible supply of electricit

Giving energy systems access to renewable energy via interconnectors helps countries phase out dirtier forms of generation.

By 2030, we estimate our interconnectors will help Britain to prevent 100 million tonnes of carbon emissions. Equivalent to planting approximately 4.5 billion trees or taking up to 64 millions cars off the road.*

*The calculation assumes that a tree consumes 22kg of CO2 per year or an average diesel or petrol car pollutes 1560kg of CO2 in a year.

Why electricity interconnection between Europe and the UK matters

To achieve a cleaner energy future, the EU and the UK need

to work closely together on the energy transition. We have so much in common already. We share similar strategic climate targets, including a legally binding approach to net zero by 2050, and our markets have been built together for decades.

With EU renewable generation expected to double from 32% up to 65% by 2030 of the total electricity mix, our interconnectors can provide more flexibility and cost-efficiency.

We estimate that by 2030 the GB power sector could reach net carbon negative emissions and is thus expected to become a net electricity exporter to Europe by 2050.

Our interconnectors bring significant value to the EU and the UK:

  • Supporting sustainability – reaching full potential of renewables by transporting excess power and meeting consumers’ demand on either side of the Channel.

  • Delivering improved security of supply and flexibility with more renewable energy sources.

  • More flexible, competitive markets and lower prices.

Multi-purpose interconnectors: a new generation of interconnector

Interconnectors can help to connect large volumes of offshore wind by acting as hubs for clean energy  connections. National Grid Ventures is developing a new generation of multi-purpose interconnector. These innovative projects aim to connect offshore wind projects here in Great Britain and to mainland Europe.
