The Eastern Link is a project to build two HVDC subsea cables that will transmit renewable energy from Scotland to England, helping to balance the UK’s power grid and support its net-zero goals. This superhighway will enhance grid stability and reduce carbon emissions by transporting clean energy to where it's most needed.
The electricity superhighway between Scotland and England, officially known as the Eastern Link project, is a significant infrastructure initiative designed to enhance the UK's power grid. It involves the construction of two high-voltage direct current (HVDC) subsea cables that will transmit renewable energy from Scotland to England, helping to balance the grid and support the UK’s net-zero goals.
Project Details
Capacity: The two HVDC cables are expected to have a combined capacity of 2 gigawatts (GW), which is enough to power around 2 million homes.
Length: The cables will stretch approximately 506 kilometers (436 km of subsea cable and 70 kilometers of onshore cable) from Peterhead in northeast Scotland to Selby in North Yorkshire, England, and from Torness in Scotland to Hawthorn Pit in County Durham, England.
Purpose: The primary goal is to transport renewable energy, particularly from offshore wind farms in Scotland, to demand centers in England, where the energy is needed most. This will help reduce reliance on fossil fuels and support the UK’s transition to a low-carbon energy system.
Timeline
Project Start: The construction is planned to start later this year
Completion Date: The cable will run from Sandford Bay, Peterhead in Scotland, to the Drax Power Station in Yorkshire, England and completion should be in 2029.
Investment and Cost
Estimated Cost: The project is expected to cost around £3.4 billion, depending on the final design and construction complexities.
Funding: The project is a joint venture between National Grid Electricity Transmission and Scottish and Southern Electricity Networks (SSEN) Transmission.
Impact
Environmental Impact: By enabling the transmission of renewable energy over long distances, the superhighway will significantly reduce carbon emissions by replacing fossil fuel-generated electricity with clean energy.
Grid Stability: The HVDC technology used in the superhighway will enhance grid stability and efficiency, allowing for better management of electricity flows and reducing energy losses.
Overall, the Eastern Link is a crucial component of the UK's strategy to achieve net-zero emissions by 2050, providing a major boost to renewable energy integration and grid resilience.
