On 12 October 2018, the Ministre d'État, ministre de la transition écologique et solidaire signed the arrêté ministériel granting Éoliennes en Mer Iles d'Yeu et de Noirmoutier (EMYN, headquartered in Nantes) the autorisation d'exploiter (AOEx) under Code de l'énergie L.311-5 for the 496 MW offshore wind electricity production installation located in the maritime public domain off the Isles of Yeu and Noirmoutier. The arrêté ministériel was published in JORF (Légifrance reference JORFTEXT000037558686) and authorises operation of the 62 turbines x 8 MW project spread over 83 km² off Vendée. Per the tightened schema, the AOEx is an operating authorisation under Code de l'énergie (analogue of the UK Ofgem generation licence), not a project-wide development consent — those (autorisation environnementale + concession DPM) are issued separately by the Préfet de la Vendée and Préfet maritime de l'Atlantique. A later modificatif arrêté was signed on 7 July 2025.</description> </invoke>
