Three years of the German Biogas Register

For more than three years now, SAG CeGIT has been working closely with the German Energy Agency (dena) to develop the German Biogas Register.


The German Biogas Register allows for simple, transparent, standardized nationwide documentation verifying the volume and quality of biogas in the natural gas grid. The application is aimed at producers, dealers and consumers of biogas that is processed and fed into the natural gas grid, i.e. biomethane or bio natural gas. The German Biogas Register documents evidence of biogas usage, particularly for power
and heat generation (Renewable Energy Sources Act (EEG)), heat generation (Renewable Energy Heating Act (EEWärmeG)) and within emission trading (Greenhouse Gas Emission Allowance Trading Act (TEHG)).

Extracts from the register document the existence of original verification for users and possible third parties (such as grid operators). For market players, they serve as standardized evidence for use in the validation of remuneration claims for power and heat production and CO2 savings for emissions trading. Since the end of 2013, it has also been possible to use the German Biogas Register to document biomethane produced from power-to-gas generation and fed into the German natural gas grid.

The concept for the German Biogas Register was developed in 2009 by dena with the support of the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) and in dialog with fourteen leading companies from the biogas and energy industry, including E.ON Bioerdgas, RWE, EnBW, Thüga, erdgas schwaben, Badenova and Balance VNG Bioenergie. SAG CeGIT has been implementing and developing the software system since 2011.

Continuous updates
Now, in 2014, more than 150 companies are already using the German Biogas Register. The system currently documents around three terawatt hours, equivalent to over 50 percent of the biomethane generated in Germany from over 80 percent of the plants producing biogas in the country. SAG is continually integrating the new legal regulations and backgrounds based on amendments to the Renewable Energy
Sources Act (EEG) and Renewable Energy Heating Act (EEWärmeG).

The German Biogas Register is expressly cited in the reasons for the draft legislation of the EEG 2012. Clearingstelle EEG makes specific reference to its mass balancing capacity while the Bundesverband der Energie- und Wasserwirtschaft e. V. (BDEW) and German grid operators recognize the register for verification purposes. It is
examined by a well-known auditing company on a regular basis.
