2-Day Carbon Intensity Forecast
Today
Values are the average, max, and min Carbon Intensity in gCO2/kWh for each day
National Data
The carbon intensity of electricity is a measure of how much CO2 emissions are produced per kilowatt hour of electricity consumed.
The ‘actual’ value (orange line) is the estimated carbon intensity from metered generation. The ‘forecast’ value (blue line) is our forecast. The carbon intensity of electricity is sensitive to small changes in carbon-intensive generation. Carbon intensity varies by hour, day, and season due to changes in electricity demand, low carbon generation (wind, solar, hydro, nuclear, biomass) and conventional generation.

WWF have implemented the API into a re-usable widget that can help people plan their energy use, switching devices on when energy is green and off when it’s not.
Regional Data
National Grid ESO forecasts the carbon intensity and generation mix of electricity consumed across 14 geographical regions in Great Britain. The spatial and temporal characteristics of carbon intensity can be observed in the map below.
The boundaries are defined according to Distribution Network Operator (DNO) boundaries. Click on a region in the map below to see the current carbon intensity and generation mix for that region. Switch to the Country tab to see the same data for England, Scotland and Wales. Click the play button to see the forecast over the next 24 hours.
