The product consists of a three-part price for electrical power, split into peak tariff (ŠT), high tariff (VT) and low tariff (NT).

The price for 1 MWh of electrical power is determined retroactively for each month according to the supplier's valid price list (separately for winter and summer), in connection with the level of consumption (in MWh) and monthly usage level of maximum hourly output.

km = W / (Pmax × T)

km - monthly usage of maximum hourly output;
W - total monthly electricity consumption [MWh];
Pmax - maximum monthly output per hour [MW];
T - number of hours in the month [h]

The monthly payment for electricity is set by the amount of electricity consumed under individual tariffs multiplied by the appropriate price for 1 MWh for the individual tariffs.

The electrical energy supplier takes on the responsibility for deviations from the customer.
