    In August 2018, the French Minister for an Ecological and Solidary Transition appointed Powernext, now integrated into EEX, to organise the auctioning of Guarantees of Origin produced by the plants benefiting from a support mechanism. The State is the sole seller during these auctions.

    Overall presentation of the auctions

    Auctions allow the purchase of Guarantees of Origin from production facilities benefiting from a support mechanism. These power plants are registered on the account of the French Climate Authority (DGEC). Only the DGEC can request the issuance of Guarantees of Origin and decide on their auctioning. For each auction, the DGEC decides to offer part or the totality of the volume of GOs available on its account for a given production period.

    How do auctions work

    Before the auction is held, EEX publishes the exhaustive list of the Guarantees of Origin issued by the State and available for purchase via the auction on the dedicated platform.

    Participants registered with EEX and ECC to participate in the auction then have a period of 7 days to submit their orders and adjust their trading limits. At the latest 2 days after the auction, the results are published and the payment and delivery of the Guarantees of Origin are made.

    Calendar of the auctions

    Please find below the calendar of the next French auctions for Guarantees of Origin. 

    Since May 2020 and upon the DGEC's request, the floor price has been communicated to participants ahead of each auction.
