Methodology

The FPC prices (€/100km) of conventional and alternative fuels is estimated by the following formula:


In the framework of this PSA, the vehicle categories, which is taken into account for the FPC price calculations, will be the following:The first factor refers to the combined consumption tested by WLTP protocol for the best-selling vehicle per fuel type and per segment. The vehicle, which was first in sales the last year for each segment and fuel type, is selected.

  • Mono fuel/fuel gas vehicle: a vehicle that is designed to run primarily on one type of fuel
  • Pure electric vehicle (PEV): a vehicle equipped with a powertrain containing exclusively electric machines as propulsion energy converters and exclusively rechargeable electric energy storage systems as propulsion energy storage systems
  • Fuel cell vehicle (FCV): a vehicle equipped with a powertrain containing exclusively fuel cell(s) and electric machine(s) as propulsion energy converter(s)

The second factor refers to the average prices of each fuel type in the last three months measured in euros/national currency per fuel unit. Since there are regional differences in the market specifications of fuels, it is recommended that MS select their reference fuels for the FPC price calculation. The selected reference fuels are shown in the related table of each MS. The average price for electricity is performed by taking into consideration the available charger types in MS level. In specific, each MS will select the charger types among the following options:

  • Home charger
  • Work charger
  • Semi-public charger
  • Public charger
  • Fast charger

Then, they determine the average price for every type of charger according to available data in €/kWh and the charging mix of these types for the last three months. Afterwards, the calculation of the average price for electricity will be estimated by adding the average price of each charger type, multiplied by the percentage of the charger mix. The electricity average price is estimated by the following formula:

In case that the aforementioned approach is not feasible, a MS can present two prices related to electricity, i.e. private charging average price and public charging average price.
