ESO
FES 2020 documents
The interactive FES 2020 Report is just one of the publications that make up the suite of FES 2020 documents.
In addition, we also provide:
- FES in 5 – a summary of the main takeaways from the report
- Data workbook – contains detailed tables, graphs and charts from our modelling
- Scenario framework – all the assumptions we use as inputs into our models
- Modelling methods – sets out information on our modelling and assumptions
- Comparison document – the key changes from FES 2019 to FES 2020
Key publications
Download this year’s Future Energy Scenarios in full or in summary. The interactive features of this document are optimised when it is downloaded as a PDF and then read on a PC laptop.
A print-ready version of FES 2020 is available here.

Get involved with FES 2021
While FES is an ESO publication, our analysis considers the whole energy system. This makes sure we’re taking into account the implications for, and interactions across, electricity, gas, heat and transport. Our scenarios reflect the year-round feedback we receive from all of our stakeholders across the energy landscape and beyond. Please continue to share your views with us.
