See where Great Britain’s electricity comes from right now. The live UK grid data above shows the national generation mix and carbon intensity forecast, helping you choose cleaner times to use electricity.
Data comes from the National Energy System Operator (NESO), which took over the system operator role from National Grid ESO in 2024. Energy Trace is independent. This national dataset covers Great Britain, not Northern Ireland.
The live GB electricity mix shows wind, gas, solar, nuclear and other sources as percentages, not power production in MW. The mix can also vary by region. See why location matters.
Electricity’s carbon footprint changes with weather and demand. Windy and sunny periods can bring more renewable power onto the grid. Learn why timing matters.
NESO’s current forecast estimates grams of CO₂ per kilowatt-hour of electricity. Lower numbers mean cleaner power. Search your postcode for a regional forecast. How we use the data.
By timing high-energy activities like charging EVs or running appliances during low-intensity periods, you can significantly reduce your carbon footprint without changing your lifestyle.
The grid works best when we work with it.
