The Great Grid Upgrade
What's energy resilience got to do with movie marathons? Find out how – and why – we’re connecting more clean energy to power the things you love.
The Great Grid Upgrade is the largest overhaul of the electricity grid in generations. Our infrastructure projects across England and Wales are helping to connect more renewable energy to your homes and businesses.
The Great Grid Upgrade will play a big part in the UK government’s plan to boost homegrown power. It will help the UK switch to clean energy and make sure our electricity network is fit for the future; carrying more clean, secure energy from where it’s generated to where you need it.
Helping to power the things you love
Whether you want a nice cuppa or a hot soak, to dance the night away or get cosy at home, we all want to be able to do what we love.
And because energy threads through everything we love to do, we're on a mission to make it cleaner, fairer and more secure for everyone.
Upgrading the grid today makes for a better tomorrow

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.
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 for an uprating of the existing 275kV overhead lines to facilitate a transmission load of 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
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.
Sea Link
A proposal for a new planned high voltage undersea electricity link between Suffolk and Kent.
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 to be built between Peterhead in Aberdeenshire, Scotland and Drax in North Yorkshire, England.
Bramford to Twinstead
We need to build a network reinforcement between Bramford Substation in Suffolk and Twinstead Tee in Essex.
Yorkshire Green
The Yorkshire GREEN project proposes new infrastructure including substations, overhead lines, underground cables and cable sealing end compounds (where underground cables meet overhead lines).
Your questions answered
The way we are all powering the things we love is changing. In the years ahead, more of our energy will come from renewables as part of the transition to a cleaner, greener future. This means we need to build new infrastructure, as well as upgrading the existing grid, to bring this clean, green energy from where it’s generated to where it’s needed by homes and businesses. The Great Grid Upgrade is the largest overhaul of the grid in generations.
If any of these projects are taking place in your local area, we’ll be advertising consultation events so that you can have your say on how this should happen. We’d love you to come along, find out more and tell us what you think.
We want to work closely with communities to make sure that we’re balancing the needs of those hosting this infrastructure, with the need to deliver lower bills, more secure energy and more clean energy for everyone. We aim to do this in a number of ways – from developing skills and employment opportunities to supporting local community projects through our Community Grant Programme.
