Reported capacity is the rated size of the listed installations, not electricity being produced now. Source dates and coverage differ, so newer facilities may be absent and historical records may remain.
How electricity works in the United Kingdom
Liberalised marketCompetitive generation and retail
Gas and wind are the main sources, with nuclear, solar and imports. Generators and suppliers trade bilaterally and on exchanges; Ofgem's price cap limits standard household tariffs. Northern Ireland is part of the all-island Single Electricity Market.
NESO, a public corporation, runs the grid in Great Britain; National Grid, SP Energy Networks and SSEN own the transmission lines, and 14 regional distribution areas deliver power. SONI and NIE Networks serve Northern Ireland.
Great Britain runs its own synchronous grid, linked to Ireland, France, Belgium, the Netherlands, Norway and Denmark by undersea direct-current cables.
Ireland and Northern Ireland share one synchronous grid and a Single Electricity Market, connected to Great Britain by undersea cables.
What does “Liberalised market” mean?
Generators sell into a wholesale market, an independent operator runs the transmission grid, and households can choose their electricity supplier. Networks stay regulated monopolies because building parallel power lines makes no sense.
Great Britain and Northern Ireland have separate system operators and wholesale market arrangements. Network owners and local distribution companies are additional organisations.

United Kingdom is in Northern Europe. Its coastal or island geography provides a different setting for electricity infrastructure from inland systems. This profile connects country reference information with the historical station inventory and reported electricity generation.
