Price comparison fuel/motorisation Standardised price comparison of conventional fuels and alternative fuels
Simple and easily comparable information on the prices of different fuels can play an important role in enabling vehicle users to better assess the relative costs of different fuels available on the market. For this reason, the European Commission has developed a method to display the unit price of different fuels at refuelling stations.
European Commission Implementing Regulation (EU) 2018/732 of 17 May 2018 establishes a common methodology for comparing the unit prices of conventional fuels and alternative fuels, which will apply in all Member States from 7 December 2020. In order to develop recommendations for the harmonised use of price comparison information, the European Union has set up an action to support the programme under the Connecting Europe Facility.
Fuels covered
Only fuels and alternative fuels available in Luxembourg are taken into account and displayed on the unit price comparison sheet.
The fuels currently covered are:
- Compressed natural gas (CNG)
- Diesel (B7)
- Electricity
- Hydrogen (H₂)
- Liquefied natural gas (LNG)
- Liquefied petroleum gas (LPG)
- Petrol - 95 octane (E10)
The list will be adapted according to the marketing of alternative fuels or combustibles in Luxembourg.
Calculation method
In order to compare fuels whose units of measurement are fundamentally different (litres, kilograms, kilowatt hours, etc.), an estimated price is calculated for each fuel, taking into account the cost of refuelling for a 100 km journey. The calculation method for each fuel is as follows:
Estimated price (Euro/100 km) = vehicle consumption (fuel unit/100 km) x fuel price (Euro/100 km)
Comparison of fuel prices by motorisation
Reference period: January 2025 - March 2025
| Logo | Fuel | Estimated price |
|---|---|---|
 |
Petrol 95 octane | 8,79 €/100 km |
 |
Diesel |
6,99 €/100 km |
 |
Liquefied petroleum gas (LPG) | 5,74 €/100 km |
 |
Hydrogen (H2) | 10,53 €/100 km |
 |
Electricity | 4,58 €/100 km |
Estimated prices in the context of European Commission Implementing Regulation (EU) 2018/732 of 17 May 2018
Vehicle consumption
Vehicle consumption' is calculated on the basis of the combined consumption measured according to the WLTP test cycle of new registrations in Luxembourg. As proposed in the above-mentioned programme support action, for each fuel the 3 car models with the most new registrations during the previous year are taken into account to calculate the average consumption per fuel. Finally, based on the number of new registrations for each of the 3 models, a weighted average is calculated. The registration data come from the National Society of Automotive Traffic (Société Nationale de Circulation Automobile - SNCA).
Fuel price
The "fuel price" taken into account is the average price observed over a period corresponding to the last calendar quarter for petrol and diesel fuels or the last calendar half-year for electricity and preceding the time of calculation.
For the various fuels, the data comes from:
Petrol/Diesel: European Commission - Prices with taxes, per CTRGPL: European Commission - Prices with taxes, per CTRCNG: average quarterly prices provided by the dealerElectricity: As generally 80% of electric car charging is done at non-public charging stations, especially at home, the estimated electricity price is composed of 80% of the utility price for residential customers. 20% is accounted for by the average price of AC charging terminals (AC, ≤ 22 kW).Since October 2021 and after the introduction of new prices for "SuperChargy" fast charging stations (DC, 150 - 350 kW), 15% of the estimated electricity price comes from AC "Chargy" charging stations and the remaining 5% from the remaining "SuperChargy" fast charging stations.
Residential customer prices: Eurostat - "Electricity prices for residential customers - half-yearly data (from 2007) (nrg_pc_204)", for annual consumption of between 5,000 and 15,000 kWh, ‘including all taxes and levies’. The average electricity price is based on the price of a standard household (annual household consumption of 5,000 kWh + 2,500 kWh for charging a 100% electric car). The reason for adjusting electricity costs on a half-yearly rather than quarterly basis is that European statistics are only available on a half-yearly basis, and electricity suppliers generally only adjust their prices once or twice a year. From 2025, the estimated price of electricity for a residential customer will be calculated internally by the Ministry of the Economy - Directorate-General for Energy - Directorate for Energy Markets, on the basis of an annual consumption of 7,000 kWh.
Prices at public charging stations: estimated average price of Chargy charging station service providers.
