EEX operates the National Registry for Biogas Guarantees of Origin (GO) on behalf of the French Ministry of the Energy.

The GO mechanism is the only system recognised in France for the tracking of energy production from renewable sources. It ensures that end consumers can verify the origin of the biogas that they consume. GOs thus provide an opportunity for individuals and companies to actively support the energy transition.

Guarantee of Origin

One GO represents one megawatt-hour (MWh) of biogas produced in a specific month and contains all relevant information on the biogas production plant.

Once produced, the biogas is injected into the grid and mixed with natural gas. GOs ensure the traceability of this injected biogas, which is used to address the demands of customers looking for more environmentally-friendly gas. Each MWh of biogas injected generates a GO that is identified by the place of production and the source material used. As a result, users can be certain that the gas they consume corresponds to a quantity of biogas that has been produced.

Before being injected into the gas grid however, the biogas is purified to ensure the same quality as natural gas. The end product is then referred to as "biomethane".

In order to issue, transfer or use a GO, you need to be registered as an Account Holder. Production Devices issuing GOs need to be registered as well. 

Account holders

To issue, transfer or use GOs in France, it is necessary to become an Account Holder in the French Biogas GOs Registry. Learn more on the registration process and who the Account Holder is on this page: 

Production devices

In order to issue GOs, the Account Holder needs to register the Production Devices on the registry. Only Production Devices located in metropolitan France, producing biogas that is injected into the gas grid and which are equipped with a gas-metering device that can measure the biogas produced and injected into the gas grid may be registered in the French Biogas Registry for Guarantees of Origin. 

Production Devices benefiting from a feed in tariff or market premium contracts

The sale of biogas is ruled differently to the marketing of biogas, which are directly linked to the way production is subsidised.

All Production Devices benefiting from a “obligation d’achat” or “complément de  rémunération” contract need to be registered in the EEX biogas registry. For contracts signed before 9 November 2020, GOs can only be requested by the obligated buyer. For contracts signed after 9 November 2020, GOs will be issued on the DGEC account and auctioned. In this case, producers do not need to become an Account Holder. They must download and fill in the registration form available below and return the document with subject "requested information about the Production Devices". 

Documentation required

To register a biogas Production Device, please access your account page on the electronic platform of the National Biogas Registry for GOs; fill in the necessary information and send the required documents to the EEX Admissions Department (go-gaz@powernext.com)

Access to the Platform

The “administrator” of an account can modify most of the information on the electronic registry platform directly. However, all changes are submitted for validation to EEX. The “administrator” can also register additional contacts who need electronic access to the registry in accordance with their roles.
