The National Grid is Great Britain’s electrical power transmission network, distributing the power generated in England, Scotland, and Wales, and importing and exporting power between Great Britain and Ireland, France, and the Netherlands.
Note: pie chart graphics exclude energy exports, as pie charts cannot show negative values
Coal: driving turbines using steam produced by burning coal
Oil: driving turbines using steam produced by burning oil
OCGT: open cycle gas turbine; burning gas to drive turbines directly
CCGT: combined cycle gas turbine; burning gas to drive turbines directly and through steam production
Nuclear: driving turbines using steam produced by radioactive decay
Wind: driving turbines using the wind
Hydroelectric: driving turbines using water naturally collected within a reservoir
Note: hydroelectric excludes pumped storage, where excess electricity is used to pump water into a reservoir in order to generate electricity at a later date. The energy used in pumped storage may be green or brown, so pumped storage is categorised under ‘Other energy’ on this page.
Note: other renewable sources such as solar are grouped together with other non-renewable sources such as waste-to-energy incinerators as other, so are categorised under ‘Other energy’ on this page.
HVDC Moyle: a 0.5GW cable between Scotland and Northern Ireland
HVDC Cross-Channel: a 2GW cable between England and France
BritNed: a 1GW cable between England and the Netherlands
East–West Interconnector: a 0.5GW cable between Wales and the Republic of Ireland
Note: negative values represent energy exports
