Entidade Nacional para o Setor Energético E.P.E. (ENSE, E.P.E.), namely the Oil Reserve unit as Central Storage Entity (CSE), is responsible for ensuring thirty days of national security reserves.
Bound Operators must provide 90 days, in which 30 days are constituted by CSE. They are responsible for the constitution of the remaining 60 days, place of which ENSE must be notified.
For the purpose of bound operators' minimum mandatory reserves counting, according to the Decree Law Nr. 165/2013 of December 16, Article 9, point 3, consumption introductions made in the year (y-2) for the 1st Quarter of the year (y) shall be counted. For the remaining quarters of the year (y), consumption introductions made in the year (y-1) shall be counted.
ENSE offers itself to replace Bound Operators on the reserves establishment, as follows:

  • Group of small operators (those who do not have their own storage capacity), ENSE shall replace them up to the total of their obligation (90 days);
  • Group of big operators (those who have their own storage capacity), ENSE shall replace them up to a further 30 days (total maximum of 60 days).

This way, Operators shall timely communicate to ENSE the reserves they wish to establish each quarter in order to enable CSE to adjust its reserves position according to the needs. Similarly, Operators shall communicate consumption introductions on a monthly basis until the 15th of the following month, as recommended by the Decree Law Nr. 165/2013.
The following table describes the reserves distribution ensured by ENSE to operators.
