Abstract: Regulation 1227/2011 on the integrity and transparency of the wholesale energy market (known as REMIT) requires generators to publicly disclose certain information about their assets. On the page " message lists", you will find a selection of relevant information relating the capacity and utilisation of these assets. This is where you will get the most up-to-date data. In the case of overlapping unavailability, whether fortuitous or scheduled, the practice is to retain the minimum available power of the unavailability over each overlapping period. The data presented on our site is retrieved every 2 hours from the source: https://www.edf.fr/tous-les-messages-doaat/feed Here you will find the dataset that allows you to visualise, on a map, the state of availability of the present, past and future nuclear fleet.
