Galp actively manages its natural gas sources, and has been seeking alternatives and diversifying its sourcing options.

Sources of supply

The main sources of supply are based on long-term contracts, both with Algeria for natural gas, and with Nigeria for LNG, totaling 5.7 bcm per year.

In parallel, Galp sources natural gas from other markets, namely in Spain and France.

The remaining natural gas requirements are covered through spot market operations.

As a rule, long-term natural gas purchase contracts define a minimum annual amount to be acquired and a margin of flexibility for each year.

These contracts usually establish a take-or-pay obligation, which obliges purchase of the agreed quantities of natural gas, regardless of whether the need occurs.
