Methodology and Calculation of Tariffs for the Utilisation of Power Transmission and Distribution Networks
With the introduction of market relations in electricity production and supply, the
need has emerged to determine tariffs for utilising power transmission and distribution
networks. For this reason, the methodology for calculating tariffs for the utilisation
of networks within the European Union has been studied. Based on this knowledge,
an appropriate methodology and calculation method are being developed in conformity
with the characteristics and needs of the Croatian electrical energy sector.
An analysis of the condition of the electricity network in the Republic of Croatia
has been conducted under the framework of the project. The basis for the analysis
was natural monopoly. In addition, the development of energy regulation in Croatia
has been analysed. The project provided an overview of applied solutions for
the calculation of tariffs for the utilisation of transmission networks in EU countries.
It was concluded that no singular methodological approach exists to the problem
of seasonal and daily fluctuations, the treatment of power etc. An approach
which includes the structure of the existing tariff system for the sale of electricity
has been suggested as an initial solution. Preliminary calculations have been performed
and work on the project continues. Its goal is to improve the methodological
approach in the context of finding a model for better allocation per voltage level,
i.e. consumer category.
