Level of obligation

The obligated entities must maintain minimum security stocks of a strategic nature equivalent to 20 days of their confirmed sales or consumption of the previous calendar year in underground storage facilities at all times. However, from March 15th to April 15th they have a month in which to adjust their stocks to the new level of obligation resulting from their firm sales of the previous calendar year.

Confirmed sales

“Eligible annual sales” refers to the sales made to end consumers by the obligated entity in the previous calendar year, or the previous year’s consumption in the case of direct consumers in the market. 

The sales transacted between shippers, exports, and shipments of products to destinations in other European Union countries are not included in the calculation.  

Confirmed sales made under an interruptible rate and supplies provided under a contract in which sales interruptibility has been included, under the conditions established in accordance with regulations, are not included either. 

The calculation for the obligation is done annually once the supply year has ended, and is applicable to the period starting April 1 and ending March 31 of the following year. 

During the first year of activity, the eligible sales are substituted for a sales forecast approved by the Ministry for the Ecological Transition.

Calculation for groups of companies

Those obligated entities that belong to the same business group can meet the obligation to maintain minimum security stocks collectively, if so authorised by the Ministry for the Ecological Transition.

Stocks that are owned or rented

Stocks held can either be the property of the obligated entity or they can be rented, but must be fully available in either case.

Location of the strategic stocks

The minimum security stocks of a strategic nature can only be held in underground storage facilities.
