National Grid has added a regionalised forecast to its Carbon intensity API service, the company announced on Tuesday 15 May. The online system forecasts the carbon intensity of power generation across GB and was initially launched in September 2017. The update means that users are now able to see the data broken down across 14 regions. It gives each area a carbon intensity score based on g/CO2/KWh and shows the percentage of energy being generated by different technologies in real-time. Director of the System Operator at National Grid, Duncan Burt said: “This tailored information can tell people when’s best to turn on the washing machine, load the dishwasher or charge the car, helping everyone to use power when it’s cleanest and most likely more cost efficient.”
