Volatile energy prices in the past period, force countries and their market
participants to find alternative and cheaper sources of electricity
production, while respecting defined environmental principles. Serbia is one
of the rare European countries that uses its reserves of dissolved gas in
the heat and electricity production. Combined heat and power plants,
although in an almost negligible amount, contribute to the diversification
of Serbia's production mix. With the presence of organized markets and local
power exchanges, sale of electricity from combined heat and power plants is
guaranteed for all producers who do not meet the conditions for acquiring
the right to feed-in tariffs. The aim of this paper is to analyze the most
profitable sale on the power exchanges of the domestic market and the
region, specifically the markets of Serbia, Croatia, Hungary, Romania, and
Bulgaria. The calculation methodology itself implies the use of average
monthly price value for the observed markets, in the period of the past
three years and nine months. In addition to the aforementioned, the costs of
cross-border capacities were considered. In order to have a clearer
overview of the results and the possibility of applying the methodology, the
amount for calculation is 1 MWh. Costs and revenues related to negative and
positive balance energy deviations are excluded from the analysis. Results
showed that sale of electricity is most profitable on Serbian power
exchange.
Keywords: cogeneration plants, Southeast European power markets, power exchanges
