Real-time carbon intensity of electricity generation for the Brighton region (South England)
Carbon intensity measures grams of CO2 emitted per kilowatt-hour of electricity generated. Brighton falls within the South England region of the National Grid, which includes power from local solar, offshore wind, and the Dungeness nuclear plant.
Intensity varies throughout the day — it's typically lowest overnight and in early afternoon (when demand is low and renewables are strong) and highest in the early evening when gas plants ramp up to meet peak demand.
You can reduce your carbon footprint by running energy-intensive appliances (washing machines, dishwashers, EV charging) during low-intensity periods, when the grid is cleanest.
Grams of carbon dioxide per kilowatt-hour — the standard unit for carbon intensity
How much CO2 is produced per unit of electricity — lower is cleaner
The breakdown of energy sources (gas, wind, solar, nuclear, etc.) powering the grid right now
Under 50 gCO2/kWh — grid is very clean, mostly renewables and nuclear
50–100 gCO2/kWh — good time to use electricity-intensive appliances
Over 200 gCO2/kWh — grid is relying heavily on gas generation
Carbon intensity measures the amount of CO2 emissions produced per kilowatt hour of electricity consumed. Lower values mean cleaner electricity. Data is provided by National Grid ESO and updated every 30 minutes.
