All wholesale oil and liquid petroleum gas product operators as well as natural gas shippers automatically and obligatorily become members of CORES as of the activity start date corresponding to the Statement of Compliance given to the Ministry for the Ecological Transition.
All of the companies that conduct these activities are automatically subject to compulsory CORES membership starting from the date they make the corresponding Statement of Compliance before the Ministry for the Ecological Transition, in which they indicate initiation of activity.
All members are obliged to hold minimum security stocks and to financially support CORES’ activity, making monthly payments based on their sales or consumption. These payments are made in accordance with the fees applicable to each product, which are calculated on CORES’ anticipated operating costs for the year and approved by means of a Ministerial Order issued by the Ministry for the Ecological Transition.
In addition to CORES members, other entities are also obliged to hold minimum stocks and pay fees based on their imported product volume or the amount acquired directly without using a wholesale operator or gas dealer as an intermediary. This is the case for retail oil product and LPG distributors, major consumers of oil products and LPG, and direct consumers in the natural gas market.
