Find a wide range of publications that provide energy insight and analysis right here, as well as information about how we're shaping the future of energy in the UK.

Our Future Energy Scenarios (FES) and other publications aim to encourage and inform debate, leading to changes that ensure a secure, sustainable, and affordable energy future.

Against a backdrop of political and technological change, it's impossible to forecast a single energy future over the long term. By providing a range of credible futures in these publications, it allows us to support the development of an energy system that is robust against a range of outcomes. 

GB 36 Bus Electricity Transmission Network Model

A 36-bus equivalent network representing the National Electricity Transmission System of Great Britain was modelled in DIgSILENT PowerFactory. The entire system was split into 36 zones for which the relevant generation and demand were evaluated. Generators within each zone were categorised into fuel types and the demand was split into active and reactive demand. Line impedances were also calculated to represent the electrical distance between the zones.

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. It has an important role to play in stimulating debate and helping to shape the energy system of the future. Find out how we develop the scenarios, how you can get involved in developing them, and of course, download the publication itself.

Markets Roadmap

We are committed to working together with stakeholders as we reform our markets to be fit for a net zero future. We share information on this transition at regular Markets Forums and through our annual Markets Roadmap.
Summer Outlook

Summer Outlook reports are designed to inform the energy industry and support its preparations, we also outline Great Britain’s projected electricity needs for the summer ahead.
Winter Outlook

The Winter Outlook Report presents our view of security of supply for the electricity systems for the winter ahead.
Whole electricity system

Find out how we are working with stakeholders to develop a smart, flexible electricity system that with deliver services more efficiently and help us meet carbon targets.
System Operability Framework (SOF)

The System Operability Framework (SOF) takes a holistic view of the changing energy landscape to assess the future operation of Britain's electricity networks.
Regional Development Programmes (RDPs)

RDPs look across the whole electricity system to unlock more network capacity, reduce constraints and open new revenue streams for market participants.
