Energy price calculation formula (€/kWh)
Terms and Conditions Effective as of October 7, 2026
PENERGIA = (POMIE + CG) × (1 + FP) + K
If, after applying the formula, the result is negative, the energy price of €0 will be applied to the time period in which this occurs.
Where:
PENERGIA: Electricity price (€/kWh), in effect for each 15-minute period of the day.
POMIE: Represents the cost of electricity (€/kWh) within the Iberian market in Portugal (OMIE PT), corresponding to the consumption period, considered in time intervals that coincide with the market time units (MTU) made available to participants in the daily market. Prices available for consultation at
www.omie.es/pt.
CG: Refers to Management Costs, which include the costs of the system’s operational management, as well as the costs related to the supplier’s TV Guide y deviations, calculated in 15-minute intervals.
K: 0.035€/kWh. Includes the sales margin and guarantees of origin.
FP (Loss Factor): Adjustment factor for losses in the Low Voltage or Medium Voltage network, for every 15 minutes of consumption, applied in accordance with the factors approved by ERSE (Energy Services Regulatory Authority).
The energy price, calculated using the formula above, will be multiplied by the quarter-hourly consumption (15 minutes) from the load diagrams provided by MOBI.E to obtain the energy cost, plus the value of the Network Access Tariffs.
If the information provided by MOBI.E does not allow for breakdown by quarter-hour, the energy consumed will be distributed evenly over the total duration of the session.
