What we do

and how we do it

In the UK, National Grid doesn’t generate or sell power. We own and operate the networks that connect homes and businesses to the energy they use. We join everything up.

Understanding Energy

How can the UK deliver low carbon energy affordably, securely and sustainably? How can it meet growing energy needs while cutting greenhouse gases by 80% by 2050? What new energy sources should replace power stations that are due to close? To meet complex challenges like these, the UK has launched a multi-billion pound investment programme that will transform the country’s energy infrastructure. Not only will it promote energy efficiency and harness a diverse mix of energy sources including cleaner fossil fuels, nuclear and renewables; it will also create new overhead power lines and substations to deliver energy where it’s needed.

Not surprisingly, there's hardly been a more exciting time to join the energy industry. National Grid are an international electricity and gas company based in the UK and north-eastern US, and this puts us at the heart of all the changes. Whatever your role, you'll help us hit stretching targets and achieve our far-reaching goal: secure, clean energy that supports our world far into the future.

making the connection

In the UK, National Grid doesn’t generate or sell power. We own and operate the networks that connect homes and businesses to the energy they use. We join everything up. Our high-voltage electricity and high-pressure gas transmission systems deliver power across Great Britain, as well as the northeast US. Once the energy enters our network, our job is to fine-tune the system to make sure supply and demand match second by second. Together, our people make sure the lights are on in schools, operating theatres and sporting arenas; and that homes are heated and water is boiled. So a career with us is about making a difference to people’s lives every day. Watch our video to see it all brought to life.

Circling the globe

We operate around 131,000 kilometres (81,000 miles) of gas distribution pipeline – enough to go round the equator more than three times.

Driving ambition

By 2050, there will be 30 million electric cars on UK roads. We need to be ready to supply power to them.

People powered

In the UK and US, we have over 26,000 people working to keep energy at everyone’s fingertips.

Life-saving work

There are over 1000 hospitals in the UK, and all of them depend on our networks for energy.

Delivering value

In an average annual domestic gas bill of £755, our gas transmission charge is £12.23 – around 2%. (Ofgem, October 2013).

Record reliability

Our electricity transmission system delivers 99.9999% of demanded electricity.

Being supportive

Over the next eight years we’ve pledged to help 34,650 vulnerable households connect to the gas network.

How we're structured

The huge scale of our operations and the complexity of our networks are matched by our ambitious plans for the future. With 12,000 employees in the UK, we’re right at the heart of the energy industry. So whichever part of our business you join, you’ll help us ensure we can supply secure, clean energy for generations to come.

We have three main areas of operation, each made up of a myriad of technical and commercial teams. And supporting us all are our corporate and business functions, from Finance to Communications and everything in between.

Electricity Transmission

We own and operate the electricity transmission network in England and Wales. We also operate (but don't own) the two high voltage electricity transmission networks in Scotland and have responsibility for the offshore electricity transmission regime. Our transmission systems are made up of approximately 7,200km of overhead lines, approximately 1,400km of underground cable and 335 substations. These all serve to connect sources of electricity generation to the distribution system. Our day-to-day operation of the network ensures that demand is fulfilled, meaning we transmit a safe, secure and dependable supply of energy across the country.

Gas Transmission

We are the sole owner and operator of gas transmission infrastructure in Great Britain. Our systems are made up of approximately 7,660km of high pressure pipes, 23 compressor stations, 7 coastal terminals and storage facilities that connect production to the distribution systems. It’s our task to see that supply meets demand, by buying, selling and using stored gas. At all times satisfactory system pressures need to be maintained and the highest quality standards upheld so that the system is operating within stringent safety limits day in, day out.

Gas Distribution

In the UK, gas leaves the transmission system and enters the distribution networks at high pressure. It is then transported through a number of reducing pressure tiers until it is finally delivered to consumers. There are eight regional distribution networks, four of which we own. Our UK distribution networks use over 130,000km of pipeline to deliver gas to around 10.9 million customers. We also manage the gas emergency number for all the gas distribution networks and other UK transporters.
