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.
Industry contributes to FES 2021
As part of our annual FES process, each year, we ask the industry for feedback, helping us to produce our scenarios.
Read a summary of what stakeholders have told us for FES 2021 together with the Scenario Framework.
Analysing the cost of each scenario
We recently held a webinar to share the output from the FES 2020 costing work.
Download the report, data workbook and the slides we used during the webinar.
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.

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.
