Great Britain electricity market: legal and regulatory guide to wholesale, networks and retail; participants, licensing and codes; REMA and net zero; interconnectors, capacity market, CfDs, price caps and smart metering
This Practice sets out an introduction to the electricity market in Great Britain (GB). It outlines the main organisations and types of organisation active in generation, transmission, international interconnection, distribution and supply, covering the GB electricity wholesale market, electricity retail market and electricity networks market, while also describing the roles of key industry stakeholders. In view of the GB electricity market’s complexity, this Practice Note presents an overview of the principal authorities and market participants in the GB wholesale and retail electricity markets. As many participants have complex ownership structures, this Practice Note, where needed, refers to the parent company. Where relevant, references include links to key sources and statistics. For a consolidated set of links to the latest key statistics published by DESNZ for the GB energy market, see Statistics at DESNZ.

National Grid in Great Britain: Legal and Regulatory Overview of Transmission, Distribution, SO/TO Split, Interconnectors, EMR Delivery Body, Divestments and the Transition to NESO
This Practice Note outlines both historic and current roles undertaken by National Grid and its owned entities within the Great Britain (GB) energy market. It covers National Grid Electricity Transmission plc, National Grid Electricity Distribution plc, National Gas Transmission plc (NGT), and National Grid’s former responsibilities as the Electricity Market Reform (EMR) Delivery Body. It also describes the previous separation between electricity transmission owner and electricity system operator functions, and how those TO and SO roles were divided within NGET. Finally, the Note assesses the effects of the newly created National Energy System Operator (NESO) on National Grid and its place within the GB energy system.
The Note intentionally uses ‘Great Britain’/‘GB’ and the ‘United Kingdom’/‘UK’ with precision. Great Britain/GB means Scotland, England and Wales (excluding Northern Ireland), while the United Kingdom/UK encompasses Scotland, England, Wales and Northern Ireland. This distinction matters because Northern Ireland’s gas and electricity markets are subject to a separate regulatory regime from the rest of the UK; see Practice Note: The Northern Ireland electricity market—an introduction for more information.
