The way we generate electricity in the UK is changing rapidly, and we are transitioning to more secure, cheaper, and cleaner forms of energy like new offshore windfarms.

The UK Government has set out a commitment to achieve net zero emissions by 2050. This means achieving a balance between the greenhouse gases put into the atmosphere and those taken out. The energy industry plays a key part in this transition, from developing renewable energy generation, to upgrading the existing electricity transmission network to allow communities across the country to benefit from this clean energy. 

Sea Link will play an important part in allowing the UK to decarbonise its energy system in a meaningful way that will not only support net zero energy targets, but perhaps more urgently, deliver a more secure and resilient energy system.

To deliver Sea Link, we would need to install a new 2 gigawatt (GW) high voltage direct current (HVDC) cable link between Suffolk and Kent, approximately 145 kilometres (km) long and predominantly offshore. 

Sea Link is one of several projects that forms part of The Great Grid Upgrade, the largest overhaul of the grid in generations.
