The average weekly price, calculated by the Energy Services Regulatory Authority (ERSE), increased by 0.1% for gasoline and 1.3% for diesel compared to last week, according to a report released today.
According to the regulator, for the week of August 28th to September 3rd, “the efficient price before tax is 0.953 euros/liter for straight 95 petrol and 0.976 euros/liter for straight diesel,” while after tax it is “1.895 euros/liter for straight 95 petrol and 1.770 euros/liter for straight diesel.”
As a result, according to the weekly report on Fuels Price Supervision, the efficient price “rose by +0.1% for gasoline and +1.3% for diesel compared to last week, taking into account the weekly change in the international price of plain 95 gasoline of +0.1% and plain diesel of +2.6%”.
ERSE also revealed that, in relation to the previous week, “it was found that the average retail prices announced on the gantries and reported on the Balcão Único da Energia were 0.2 cents/litre higher than the efficient price for that week for straight 95 petrol and 1.7 cents/litre higher for straight diesel”.
So, in percentage terms, “straight 95 petrol was advertised on the gantries at 0.1% above the efficient price and straight diesel was advertised at 1.0% above” this price.
The efficient price is an average weekly price determined by ERSE, which results from the sum of several factors: fuel prices on the international reference markets and the respective maritime freights, primary logistics, including the strategic and security reserves of the National Oil System, the extra costs of incorporating biofuels and the retail component plus the respective taxes.
Finally, with regard to discounted prices, published by the Directorate-General for Energy and Geology (DGEG), “plain 95 gasoline showed a deviation of -2.0% from the efficient price and plain diesel of -2.6%”.
In absolute terms, these estimates published by ERSE are “-3.8 cents/litre lower for straight 95 petrol and -4.5 cents/litre lower for straight diesel than the respective efficient prices”.
