Where Great Britain’s electricity is coming from, updated every half hour.
The figures are Great Britain’s electricity generation mix for the latest half hour, including estimated small-scale generation. Renewable means wind, solar, hydro and biomass.
The map is an illustration of that mix. Each fuel is drawn in its colour from the list, and the bigger its share, the more of its sites you see. Sites are real stations and wind farms in approximate places, but they don’t show each site’s own output. Wind speeds are model estimates, not turbine readings. Gas routes are simplified.

Energy: derived from Ofgem’s regional cap tables; a benchmark for default tariffs, not an average of available deals or a cap on your total bill. Water: select your area separately. England and Wales show company averages; Scotland offers an average or standard Council Tax band charges; Northern Ireland explains its domestic billing arrangements. Water-only figures exclude sewerage. How we calculate these figures →
Estimate a yearly and monthly electricity and gas bill from your usage, prefilled with your region’s price-cap rates.
Calculate my bill →Test a unit-rate rise or fall against the energy you expect to use over the next 90 days.
Plan a price change →Put a price on the things you run, from a kettle to business equipment, using its power rating and your unit rate.
Check running costs →Free to use. No sign-up. Calculators run in your browser and use the numbers you enter.
Use the last three complete years of national consumption to plan the next three months.
The starting input is an editable example. Use annual consumption from your bills. This uses the national household pattern; heating systems and individual homes differ.
Three-month estimate
4,366 kWh
39.7% of the annual usage you entered
Using each historical year separately gives 4,225–4,516 kWh. This range describes those three patterns; it is not a forecast confidence interval.
We average each quarter’s share of annual UK consumption across 2023, 2024 and 2025, then apply that seasonal pattern to your annual usage. The source is quarterly, so we spread consumption evenly across days within each quarter. Monthly bars are allocations, not measured monthly data. Weather, occupancy, efficiency and operating hours can change your actual usage. No future weather or price prediction is included.
