Hydrocarbon minimum security stocks are preferably located in Spain and are stored so that they can be distributed for consumption in accordance with market needs.
With the appropriate authorisation, minimum security stocks of oil-based products, including strategic reserves, may be stored in other EU Member States, provided that there is an intergovernmental agreement with that Member State which guarantees its availability so that domestic supply is not harmed. Currently such agreements are in place with France, Italy and Portugal.
The level of minimum security stocks stored by parties under obligation outside Spain, in virtue of the above legislation, as of 31 December 2007, and in accordance with the pertaining licenses issued by the Directorate General for Energy Policy and Mining, is a percentage equivalent to 1.48% of the overall obligation.
