Electrical power is needed in all aspects of life, and because of that the cost of electricity is a crucial parameter. This cost consist of two main part: the network access fee and the cost of energy. Customers can choose from different platforms if they decide to purchase: they can get energy through the liberalized electricity market, or – if they are authorized – they can buy it within the confines of universal services. The prices of the universal service are defined by the Regulatory Authority, unlike the liberalized market which is barely regulated. Wherever the user gets the energy from, it will be delivered through the electric power grid. Every economic participant is entitled to use this network but they have to pay the network access fee.
I will review the compounds of the network access fee. These are regulated and set by the Regulatory Authority. The concept of this regulation and also the fee elements of profiled consumers who access the grid on a low-voltage level are being explained.
Beside that, I show the determination of the cost of electricity within the confines of the universal services. I review the certain pricing methods and the conditions of usage. I examineThe A1 tariff’s trends from 2012 to 2014.
I introduce a self-made modelling method which can approximate the average cost of electricity. The model realizes a simplified procurement strategy. I choose an exact distribution system operator to examine the results and the functioning of the model. I also consider the effects of the feed-in tariff support for renewable energy sources.
