Obligation to maintain minimum security stocks

The obligated entities must hold 20 days of confirmed sales at all times. 

In their first year of activity, new obligated entities substitute the eligible sales form for a sales forecast approved by the Ministry for the Ecological Transition. In the case of direct consumers that are availing themselves of the right to access for the first time, their obligation can be calculated based on their confirmed consumption of the previous year.

Obligation to pay the fee

All entities obliged to maintain stocks are compelled to financially support CORES activities, paying annual contributions (fees) based on their sales or consumption. The obligated entities must submit an annual sales report and the corresponding payment, by means of self-assessment, in accordance with the sales of the year prior to the year the declaration is being made.

Obligation to send in periodic information

The entities obliged to maintain minimum security stocks and the diversification of natural gas must send in the following information to CORES using the infoCores platform:

  • Before the 20th of each month, the monthly forms corresponding to the 15 December 2008 Resolution of the Directorate-General of Energy and Mining Policy.
  • Before 20 February, the form on eligible sales or consumption for the calculation of minimum security stocks.
  • Before 30 April, the annual sales report.
  • Before 30 April, a list of imports by country of origin corresponding to the previous calendar year.

In addition to the entities obliged to maintain stocks, the distributors, carriers and the System Technical Manager have to provide the following information to CORES, making it possible to verify the data submitted by the obligated entities:  

  • Monthly forms corresponding to the 15 December 2008 Resolution of the Directorate-General of Energy and Mining Policy

All forms are available on the calendar of obligations.

infoCores is the secure information exchange platform that CORES has designed to ensure security and facilitate management of the information submitted by all the entities obliged to do so. Access to infoCores requires the digital signature corresponding to the company representative having the appropriate authorisation, which will be verified, in order to present the documentation to CORES. One entity can register various representatives.
