The National Grid covers most of mainland Great Britain and several of the surrounding islands, and there are interconnectors to Northern Ireland and to other European countries. Power is supplied to consumers at 230 volts AC with a frequency of 50 Hz. In 2023 about a third of electricity used in Britain was generated from fossil gas and two-thirds was low-carbon power. Wind generates the most low-carbon power, followed by nuclear some of which is imported from France.[5] The government is aiming for greenhouse gas emissions from electricity in Britain to be net zero by 2035.[6]

The use of electricity declined in the 2010s and early 2020s, attributed largely to a decline in industrial activity and a switch to more energy efficient lighting and appliances.[7] However demand is projected to increase considerably due to electrification, such as heat pumps[8] and electric vehicles.[9]

UK energy policy includes capping some residential energy price rates,[10] and wholesale prices for some new low-carbon power can be stabilized by the government.[11]

Nationalisation plans are currently underway following the proposed introduction of Great British Energy subsequent to the 2024 King's Speech, which also oversaw increased dedication towards net-zero targets by 2050. This is further emphasised via GB Energy through heavy investment in renewable energy sources, such as tidal power and offshore windfarms. The future body also intends to operate and manage clean power projects at a state level, in contrast with private entities having done so for several years.

Under the most recent estimates, the plan will amount to £8bn. for the government, a figure criticised by the opposition and media alike, although Energy Secretary Ed Miliband has claimed it will have an environmental impact in forwarding sustainability, as well as predicting that it will reduce average electricity thresholds by £1,400 universally. The entity will remain in preliminary stages before implementation of the Great British Energy Bill, whereupon it shall be established after royal assent given in accordance with the law of the United Kingdom.
