Electricity Transmission Network Explainer
Great Britain’s Electricity Transmission Network
NESO's Electricity Networks Explainer package offers a comprehensive view of GB’s electricity transmission network, including how it is changing and why this change is needed.
The package’s two publications act as a guide, supporting people of all backgrounds and knowledge levels in understanding how decisions are made across the network. The publications also discuss the trade-offs between different technologies and the various organisations involved in the process.
Explainer of Electricity Transmission Networks
This is a short, plain English guide to electricity transmission networks in Great Britain, intended to be accessible to all. This guide will build your understanding and answer your questions on how the electricity transmission system is planned, operated and expanded.
Detailed Appraisal of Electricity Transmission Networks
This is a more technical, longer document that provides further detail on GB’s electricity transmission network. Intended for those with a technical background, pre-existing knowledge of the industry, or an appetite to learn more.
