Two tools become one: Transmission system operators 50 Hertz and Tennet are now jointly recording and analyzing the origin of electricity in the European bidding zones.

The transmission system operators 50 Hertz and Tennet have launched a digital tool that provides hour-by-hour information on the nature of the electricity in the individual European bidding zones. It is called "Green Grid Compass" - GGC for short.

At the launch of the tool on February 18, the grid operators highlighted the benefits in a joint press release. With public access to the values of how much renewable energy is currently in the grids or can be expected the next day, electricity consumption can be managed intelligently.

Companies and private individuals could thus adapt energy-intensive production processes or the charging of electric vehicles. This ultimately leads to lower CO2 emissions at times with a high proportion of green electricity. The system also supports companies with sustainability reports by providing a database.

The two companies are working together on the GGC with the Research Center for Energy Economics (FfE). This made it necessary to combine the previous systems "eCO2grid" (50 Hertz) and CO2-Monitor (Tennet). The GGC now provides hourly data on CO2 intensity and the proportion of renewable energies in the electricity bidding zones. The information is available as a reference, as a live value or as a forecast for the next day.

In their press release, 50 Hertz and Tennet also name the first partners who are testing the system: Bayernwerk, Mercedes-Benz, Clever-PV, Covestro, Edenberg, EWE Hydrogen, Stromdao, Lichtblick, Unternehmertum, VK Energie and OLI Systems. Other interested parties can participate, and private individuals can also integrate the GGC into their IT systems via a suitable interface.

The free interface and the Green Grid Compass data pool are available on the Internet.
