About Weston Marsh to East Leicestershire
Weston Marsh to East Leicestershire is a proposal by National Grid Electricity Transmission (National Grid) to reinforce the high voltage transmission network between Lincolnshire and the East Midlands.
Our proposals for Weston Marsh to East Leicestershire are part of The Great Grid Upgrade.

National Grid sits at the heart of Britain’s energy system, connecting millions of people and businesses to the energy they use every day. We bring energy to life – in the heat, light and power we bring to our customer’s homes and businesses; in the way that we support our communities and help them to grow; and in the way we show up in the world. It's our vision to be at the heart of a clean, fair and affordable energy future.
We are working to build a cleaner, fairer, and more affordable energy system that serves everyone – powering the future of our homes, transport and industry. We believe by acting now, the UK can become the world’s first major clean economy, creating growth and jobs for communities across Britain.
National Grid is a group of companies, and one of those companies, National Grid Electricity Transmission, owns, builds and maintains the network in England and Wales. It's National Grid Electricity Transmission that's developing plans for Weston Marsh to East Leicestershire.
Within the National Grid Group there are other distinctly separate legal entities, each with their individual responsibilities and roles. More information about National Grid can be found on the about us section of National Grid’s website.
NGET owns, builds and maintains the high-voltage electricity transmission network in England and Wales. This network operates primarily at 400,000 volts (400kV) and 275,000 volts (275kV).
It's NGET that is developing plans for Weston Marsh to East Leicestershire and is the electricity transmission arm within National Grid.
The existing transmission system – the infrastructure including pylons, overhead lines and underground cables which transports electricity around the country – was largely built in the 1960s. It was not designed to transport electricity from where it is increasingly being generated today – offshore and from solar.
Electricity demand in Britain is forecast to at least double by 2050, increasing the amount of energy we need to transport to homes and businesses. Alongside this there has been huge growth in offshore wind, interconnectors and nuclear power which means that more electricity will be generated in the years ahead than the current network is able to transport securely and reliably.
New power lines are needed to meet the Government target of connecting 50 GW of offshore wind by 2030, enough to power every home in the country with clean, green and more affordable energy.
The Great Grid Upgrade is the largest overhaul of the grid in generations and will future proof the Grid for years to come, facilitating the transition to a clean and affordable energy future.
