KOMPARATIVNA ANALIZA RAZLIČITIH METODA ZA OBRAČUN DEBALANSA

Abstract

In 2022, privileged producers from renewable energy sources in Serbia faced the economic challenge of quiting the so-called feed-in tariffs for selling on the free electricity market. This scenario came about because of the enormous increase in electricity prices in Europe. Quiting feed-in tariffs and participating in the free market brought with it certain novelties. The planning of the production if the power plants connected to the distribution network, and that in an hourly resolution in the morning for the whole following day, suddenly gained importance, primarily because of the imbalance costs that all power plants that sell their production on the free market have to pay. Since such small power plants did not previously have this obligation, this challenge becomes greater. The main problem is that the vast majority of these power plants do not have historical production data in an hourly resolution, nor do they have installed adequate metering equipment or remote reading of the data required for good planning. However, planning is not the topic of this paper, but its consequences, which is the so-called imbalance (deviation of realized production from planned). Two different calculation approaches, colloquially called the "realization" and the "planning" method, can be used for the financial calculation of the resulting imbalance. Both will be shown and described in detail in this paper, with their comparison and commentary on the comparative results on practical examples. At the very end, conclusions will be drawn for further improvement of the existing practice with the aim of facilitating the understanding of this issue both for existing and new owners of the power plants.
