ESO
Welcome to the ESO 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.
We’re just 30 years away from the net zero deadline, which isn’t long when you consider investment cycles for gas networks, electricity transmission lines and domestic heating systems.
FES has an important role to play in stimulating debate and helping to shape the energy system of the future.
This year’s scenarios have had to adapt and expand to accommodate societal as well as system changes.
Our FES 2021 Call for Evidence is now closed
To find a summary of what stakeholders have told us for FES 2021.
Please read the summary here.
How we develop scenarios
The Future Energy Scenarios are the result of in-depth analysis by our own team of experts, combined with stakeholder insight and input from industry specialists. This collaborative approach gives us the breadth and depth of knowledge we need to develop realistic scenarios for the future of energy in the UK. Our scenarios and modelling are used by National Grid ESO and wider energy industry.

Zero carbon explained
We're aiming for electricity to be zero-carbon by 2025, watch the videos and find out what zero carbon means and why it's so important for the energy industry.
Our strategy
National Grid ESO is preparing great Britain's electricity system to be able to run purely on zero-carbon electricity by 2025 whilst at the same time keeping the lights on for homes and business 24/7.

Introducing Bridging the Gap 2020: Peaks and Troughs
Last year the ESO built on the success of our Future Energy Scenarios by launching FES Bridging the Gap to net zero. The report gives a collaborative view from across and outside the energy industry, focused on going beyond FES to recommend actions.
