The Azorean government justifies the adjustment in the maximum retail price with the “recent variations in the international market of reference prices for petroleum and energy products”.

From Sunday, February 1st, unleaded 95 octane gasoline will cost €1.598 per litre in the archipelago, representing a decrease of 2.2 cents.

Road diesel will remain at €1.474 per litre.

The price of colored diesel for agriculture and fishing, defined in another decree, will also remain the same as in January.

The price of coloured and marked diesel used in agriculture is set at €1.103 per litre, and coloured and marked diesel used in fishing is set at €0.913 per litre.

Butane gas sold to the public at the retailer's establishment, in bottles of 26 litres or more, and piped butane gas will cost €1.686 per kilogram, 0.1 cents less than in January (€1.687).

Butane gas sold to the public at the retailer's establishment, in 24-litre bottles made of lightweight materials (up to eight kilograms of container), is set at €1.886 per kilogram, 0.3 cents more than the previous month (€1.883).

Bulk butane gas will cost €1.278 per kilogram, a decrease of 0.6 cents compared to January (€1.284).

The maximum prices for petroleum and energy products in the Azores are "changed on the 1st of each month and in amounts equivalent to the variation in the monthly European Price (PE) value".

In December 2024, the Azorean government increased the Tax on Petroleum and Energy Products (ISP) by 9.8 cents per litre for gasoline and 5.8 cents per litre for diesel.

In the region, 59 cents of ISP are charged per litre for gasoline and 40 cents for diesel.
