Insights

Our wide range of publications provide energy insight and analysis, as well as information about how we are shaping the future of energy in the UK.

Our Future Energy Scenarios (FES) and other dual fuel System Operator (SO) 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 is 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.
