French Guarantees of Origin Registry

French Guarantees of Origin Registry

Powernext activities were integrated into EEX as of 1st January 2020. 

EEX now operates the National Registry for Guarantees of Origin (GO) under appointment from the French Ministry of ecology, sustainable development and energy. The GO mechanism is the only system recognized in France for the tracking of energy production from renewable sources. It ensures that end consumers can verify the origin of the electricity that they consume. GOs thus provide an opportunity for individuals and companies to actively participate in the energy transition.

Guarantee of Origin: lifecycle and statistics

One GO represents one MWh of electricity produced in a specific month and contains all relevant information on the power plant.

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: 

Go Registry


Issuance: The issuance of GO  can be requested up to 5 months after the end of the relevant production period and they are valid for one year following the end of the production period to which they apply. Once expired, they can no longer be used, nor transferred.

Use or Cancellation: The GOs are used and effectively cancelled by power suppliers or specialized companies for the marking of electricity intended for the consumer.

Transfer: It is possible to transfer active GOs  within the National Registry from one account holder to another. As EEX is a member of AIB (Association of Issuing Body), its account holders can import and export guarantees of origin electronically from and to other European countries.

Regulation: The European regulation applicable to the Guarantee of Origin system is Directive n°2009/28/CE dated 23 April 2009 relative to the promotion of the use of energy generated from renewable sources. The European Directive was transposed into French law in the code of energy, notably in articles L314, R314 and R333, modified by decree n° 2016-944 dated 11 July 2016.


Each quarter, EEX publishes statistics about the Guarantees of Origins which transited through EEX Registry. The detailed figures are available up left of this page in the document named Guarantees of origin - Data 2007-present (zip).
