The energy transition
The UK electricity system has been changing over recent decades as generation has shifted away from coal and toward lower-carbon sources such as wind, solar, nuclear, and interconnectors.
This page tracks that change in real time by showing the current generation mix alongside indicators like carbon intensity and demand. The aim is to provide a clear, neutral snapshot of the system as it operates today.
Wind power is a major contributor to low-carbon generation in Great Britain, particularly from offshore wind in the North Sea and onshore sites across the country. Output varies with weather, so record levels tend to occur during sustained high-wind periods.
New wind power records are set regularly, and between 3:30pm and 4:00pm on 17th December 2025 British wind farms averaged a record 21.97GW of generation.
