The UK has set a clear ambition for our country to be a global leader in clean energy. The Government has set a commitment to reach net zero greenhouse gas emissions by 2050 and an ambition to connect 50 GW of offshore wind by 2030 – enough energy to power every home in the country. 

To achieve this, offshore wind is being developed at scale and around 60% of the current offshore wind projects will come ashore along the East Coast. 

Couple this with new nuclear generation proposed at Sizewell C and greater interconnection with countries across the North Sea, we expect to see a significant increase in the level of renewable and low carbon electricity generation connecting in East Anglia. 

While our existing high voltage electricity network in East Anglia has been sufficient until today, it doesn’t have the capability needed to reliably and securely transport all the energy that will be connected by 2030 while working to the required standards. 

In the first half of this decade, we are investing significantly in upgrading the existing network, but that still won’t deliver the capability that is needed. We need to reinforce the region’s network and to increase the network capability to carry the clean green energy that is proposed. 

The East Anglia Green Energy Enablement (GREEN) project is a proposal to build a new high voltage network reinforcement between Norwich, Bramford and Tilbury.  

It will play a vital role in delivering electricity efficiently, reliably, and safely and will support the UK’s move to reduce carbon emissions.
