Our projects

Cross Border Connection

This project is designed to strengthen the electricity network between Scotland and England. It will connect new sources of energy in the Scottish Borders to the wider network.

Weston Marsh to East Leicestershire

We are proposing roughly 60 km of new 400 kV overhead line which would run east to west from the infrastructure at Weston Marsh substation(s)

Eastern Green Link 5

Eastern Green Link 5 (EGL 5) is a new primarily offshore high voltage electricity link, with associated onshore infrastructure, between Scotland and England.

Chesterfield to Willington

A proposal for a new overhead line to connect at a new 400 kV substation at Chesterfield in Derbyshire and the existing Willington substation in South Derbyshire.

Eastern Green Links 3 and 4

A proposal for two new primarily offshore high voltage electricity links and associated onshore infrastructure between Scotland and England.

Sea Link

A proposal for a new planned high voltage undersea electricity link between Suffolk and Kent.

Yorkshire Green

Construction has begun on the project which will upgrade existing infrastructure in North Yorkshire and build a new 10km electricity overhead line along with a short section of underground cables, sealing end compounds and two new substations.

Bramford to Twinstead

We need to build a network reinforcement between Bramford Substation in Suffolk and Twinstead Tee in Essex.

Norwich to Tilbury

A proposal to reinforce the high voltage power network in East Anglia between the existing substations at Norwich Main in Norfolk, Bramford in Suffolk, and Tilbury in Essex.

Brinsworth to High Marnham

A proposal to upgrade the existing 275kV overhead lines to 400kV and the development of three new substations to help carry more green power from the North of England to the Midlands.

Grimsby to Walpole

A proposal to build a new high voltage overhead line in Lincolnshire, including building new pylons and new substations.

North Humber to High Marnham

North Humber to High Marnham
A proposal to build a new high voltage electricity transmission line between Creyke Beck in the East Riding of Yorkshire and High Marnham in Nottinghamshire.

Grain to Tilbury

A proposal involving the replacement of the existing 1960s Thames Cable Tunnel beneath the Thames between Tilbury and Gravesend.

Eastern Green Link 1

EGL1 is a two gigawatt (GW) high voltage direct current (HVDC) electrical superhighway to be built between the Torness area in East Lothian, Scotland and Hawthorn Pit in County Durham, England.

Eastern Green Link 2

EGL2 is a 2GW high voltage direct current (HVDC) electrical ‘superhighway’ cable link beginning construction between Peterhead in Aberdeenshire, Scotland and Drax in North Yorkshire, England.

Carlisle to Newcastle

Carlisle to Newcastle is a proposal in its early stages of development to upgrade the electricity network between the North West and North East of England.

The last major upgrade of the grid was in the 1950s and 1960s when higher voltage transmission lines were installed to meet a rapidly growing demand for electricity.

Where the early supergrid was built around the power plants of the Midlands, tomorrow’s network will connect clean energy out at sea, meaning new infrastructure in new places.

We’re committed to engaging communities as we develop our proposals to understand what’s important to them and endeavour to deliver initiatives that support those priorities.

We work with local communities and stakeholders to understand what’s important to them and endeavour to deliver initiatives that support those priorities – from developing skills opportunities to supporting local community projects through our Community Grant Programme. 

We work with relevant authorities as we develop our engagement plans, to ensure they’re tailored to, and meet the needs of, the local communities. 

We conduct ongoing engagement and undertake consultation exercises. For this we use different methods of communication to ensure we’re hearing a wide range of views across these communities, which hugely supports with the development of our projects.

The Great Grid Upgrade is the largest overhaul of the electricity grid in generations, connecting more clean, secure energy to power the things we love.
