Electricity Ten Year Statement
We have published an update to our Electricity Ten Year Statement (ETYS). The ETYS is the ESO’s view of future transmission requirements and the capability of Great Britain’s National Electricity Transmission System over the next 10 years.

Welcome to National Grid ESO

We make sure that Great Britain has the essential energy it needs by ensuring supply meets demand every second of every day. Find out more about what we do for Great Britain.

Our RIIO-2 Business Plan

Since the start of RIIO-2 in April 2021, we have been evolving to meet the changing needs of the energy industry. And we are on track to make sure that the electricity system can support 100% zero carbon power as soon as 2025.

Electricity and me

Does boiling the kettle really sap electricity, and are energy saving light bulbs that much better than their conventional cousins?

Future Energy Scenarios

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