Carbon Intensity API


National Grid, in partnership with Environmental Defense Fund Europe and WWF, has developed a Carbon Intensity forecast for the GB electricity system, with weather data provided by the Met Office.

This site explains and demonstrates the Application Programming Interface (API) available so that tech developers can create consumer friendly apps.


2-day Carbon Intensity forecast

Today

Timestamps in the graphs above are in UTC time and figures above are the Average, Max and Min for each day.

Today's data

The higher the values, the more CO2 is being emitted per kWh of generation.

The ‘actual’ value (blue line) indicates what actually occurred. National Grid balances supply and demand second by second in real time so the difference is driven primarily by changes in the weather that can impact the output of solar and wind generation. It also accounts for the small tweaks the control room make to the output of traditional power stations.

Carbon Intensity Forecast (-24hrs to +48hrs)



Select a start and end date below, the data is retrieved in UTC time and returned in CSV format. We currently only have available data in the API from 26/09/2017.

Examples

WWF has implemented the API into a re-usable widget that can help people plan their energy use, switching things on when energy is green and off when it’s not.





About the API

The new software combines National Grid’s deep knowledge of the GB energy system and weather data provided by the Met Office to forecast the carbon intensity of GB electricity over the next 48 hours, and the resulting carbon emissions.

The goal of this API service is to allow developers the chance to produce applications which can be used by electricity consumers, with the potential to influence behaviour in their electricity usage along with making consumers more aware of their Carbon footprint.
