What we do
What we do
We ensure that Great Britain has the essential energy it needs by making sure supply meets demand every second of every day.

Back What we do View
Our people

We work with a whole range of experts, including engineers, academics and industry professionals so that we can safely deliver affordable and clean energy to customers. As we build a greener electricity system of the future our people know they are shaping the future for generations to come.

Our strategy

Find out more about our strategy, our RIIO business plan and annual reports and look towards our emerging future role at the heart of a new Future System Operator (FSO).

Becoming the Future System Operator (FSO)

Unparalleled change is needed to deliver clean, secure, and affordable energy for the country. The FSO is being set up as an independent organisation with a view across the whole system to lead this change.

How we operate

National Grid ESO moves high voltage electricity from where it’s generated, such as a wind farm, through the energy system. But who else is part of the British electricity system?

Electricity National Control Centre

From hospitals to households, telecoms to transportation, our society relies on electricity. Our control centre makes sure there is always a reliable and safe supply as we move megawatts around the country.

Electricity Markets

Whether you’re interested in the innovation underway in the ESO Markets team or are looking to brush up on market fundamentals, you’ve come to the right place.

Balancing the Grid game

To give you some insight into the world of balancing the grid, we’ve developed a game where you can attempt to keep the grid stable while facing some of the challenges our control room operatives experience daily.
Electricity explained
Electricity explained
We’re experts in all things electricity – how much we use, where it comes from and how it moves around Great Britain. And we want to share all that knowledge with you.

Electricity and me

At National Grid ESO, we have an ambition to run the grid zero carbon by 2025. And anything you can do to adopt greener habits will help. Become a megawatt master – in this section of Electricity Explained.

How is electricity generated?

The way electricity is generated is changing as we head towards a greener future.

How does electricity move around?

Do you know your DNOs from your ESOs? And how does electricity actually get to your home, around the country and overseas?

How do we balance the grid?

Inertia, frequency, voltage, thermal, constraints… these are just a few of the factors that go into the highly complex process of balancing the grid.

Power cut in your area?

Experiencing a power cut? Find out what to do and who to contact.

How is electricity priced?

There are three main models that determine the price of electricity. What do we use in GB and around the world?

Our progress towards net zero

Read the story of how the ESO has decarbonised its electricity system to date, offering a blueprint to other countries around the world to help them reduce emissions.

Future Energy Scenarios (FES)

Future Energy Scenarios (FES) represent a range of different, credible ways to decarbonise our energy system as we strive towards the 2050 target.

Innovation

Innovation is critical to helping us meet the challenges of transitioning to a zero carbon future. As we sit at the very heart of the energy system, we play a central role in overcoming these challenges.

Projects

At National Grid ESO our projects all contribute towards our effort to make the grid ready to operate with 100% zero carbon electricity by 2025.

The Pathway to 2030 Holistic Network Design

The Pathway to 2030 Holistic Network Design (HND) is a major step for Great Britain in delivering cheap, clean energy from offshore wind.

Virtual Energy System

National Grid ESO have launched an ambitious, industry-wide mission to digitise our energy system. We call it the Virtual Energy System.
Industry information
Industry information
Whether you’re a balancing provider looking to supply services to us, trying to find the latest Grid Code, or looking for the latest TNUOS charging guidance, you can find all the information you need in our Industry Information hub.

Back Industry information View
Balancing costs

Balancing costs are those costs associated with (A) the Balancing Mechanism, (B) balancing services, and (C) energy trading.

Balancing services

We procure services to balance demand and supply and to ensure the security and quality of electricity supply across Britain's transmission system.

Charging

These pages contain details about the charges that users of the electricity transmission system have to pay, how they are calculated and what changes are currently being considered by the industry.

Codes

Our team of code administrators oversees all aspects of the code modification processes and related meetings. So whether you’re new to the process, or experienced in the way it all works, we’ll help you get to the information you need.

Connections

In this section, we’ve got everything you need to understand the connections process. Including what you need to do to connect to, or make use of the National Electricity Transmission System (NETS).

Industry data and reports

These pages contain data and support for users of the National Electricity Transmission System (NETS). Here you will find the latest operational data, forecasts, and reports.

Network access planning

Our Network Access Planning engineers are responsible for assessing, co-ordinating and sanctioning the planned release of assets from the National Electricity Transmission System.
