Why are Interconnectors Needed?

The UK Government has identified interconnectors as being vital for achieving an integrated energy market in which consumers get the best value for their money. By widening access to international energy markets, interconnectors help increase competition and reduce energy prices for consumers.

It is estimated by the Government that demand for electricity in the UK could double by 2050 as the UK seeks to meet its net zero climate commitments. Much of this increase in demand will be driven by the electrification of vehicles, heating and industry. With the ability to transmit electricity in both directions, interconnectors help ensure security of supply and provide grid operators with flexibility in manging demand.

Interconnectors have also been widely recognised as playing key role in the decarbonisation of energy markets. Interconnectors enable the greater integration of low-carbon energy sources into the energy mixes of the connected countries, thereby reducing reliance on fossil fuel-based energy sources like coal, gas and oil. The benefits of interconnectors in terms of decarbonisation has been noted in research produced for the UK Government, which finds that an increase in interconnector capacity would substantially decrease carbon emissions and support the UK’s transition to net zero by 2050.

There are currently six existing interconnectors between the UK and other countries, with others proposed (including between the UK and countries such as Ireland, Germany, Norway, Denmark and France). In light of the key role of interconnectors will play in the UK’s energy future and tackling climate change, the Government has made a commitment to realise at least 18GW of interconnections by 2030 – a three-fold increase when compared to today.
