CO2 intensity figures are electricity info calculations using Elexon output figures. See the full methodology.
* There are limitations and simplifications in providing real time values; our Average 2019 CO2/kWh value is calculated on the same basis as Current and Last 24 hours for comparison, and that value may change as we modify our methodology for calculating real time values; the actual figure for 2019 will be slightly different.
The Last 24 hours average is a weighted average, so the carbon intensity at periods of high demand affect the average more than the carbon intensity during low demand.
Oil output is included in “other” in pie charts and graphs but is treated separately for carbon intensity calculations.
A warning on white goods
If you intend using carbon intensity data to decide when to run white goods like washing machines and tumble dryers, please take note of Fire Service advice not to run such equipment at night or while unattended.
