ANDthis indicator is an average weekly value calculated by ERSE taking into account international rates of refined fuels and freight, logistics, reserves, biofuels, retail and taxes.

 

The regulator points out, however, that this price is a “referential calculated by ERSE on the basis of the main costs associated with the availability of fuel to the consumer”, adding that “it is not a regulated price, a maximum price or a recommended price, since the public sales prices are freely defined by each operator”.

Thus, for week 17 to 23 August, the efficient pre-tax price is EUR 1,006/litre for simple petrol 95 and EUR 1,255/litre for simple diesel, and “after the inclusion of the ISP, the addition rate on CO2 emissions and VAT”, it is EUR 1,984/litre in simple petrol 95 and EUR 2,102/litre in simple diesel.

“ In view of the previous week, the efficient price increased by 3.8% in petrol and 4.0% in diesel oil,” said ERSE, pointing out that this evolution results, “in particular, from the variation in international gas and diesel prices, which are the most directly related references to the cost of fuels sold at the gas stations.”.

During this period, the international quotation of single petrol 95 and diesel increased by 11.0% and 9.8%, respectively.

The regulator points out that to understand the evolution of fuel prices, “the most important reference is not the quotation of the barrel of crude oil, but the international quotations of gasoline and diesel already refined”, considering shipping freights, logistics costs, the incorporation of biofuels, marketing and taxes.

In addition, it indicated that discounted prices this week were below the efficient price at 2.6 cents/litre in plain petrol 95 and 5.3 cents/litre in simple diesel, corresponding to deviations of -1.3% and -2.6%, respectively.

With regard to portico prices, the average sales prices to the public announced at supply stations, as reported at the Single Energy Balcony, were 2.5 cents/litre above the efficient price in gasoline 95 simple and 0.9 cents/litre above in simple diesel, and these differences corresponded to deviations of 1.3% 0.4%, respectively.
