R. Pašičko, D. Kajba, J. Domac: KONKURENTNOST ŠUMSKE BIOMASE U HRVATSKOJ U UVJETIMA... Šumarski list br. 7–8, CXXXIII (2009), 425-438 The article presents a mathematical economic model which explores the impact of CO2prices on investment decisions related to the construction of new electrical power plants or a change of fuels in the existing plants. The model determines emissions allowance prices at which biomass becomes more competitive than other technologies. Changes in CO2prices affect short run marginal costs (SRMC) and long run marginal costs (LRMC) of electrical energy production, where a decision on the replacement of fuel in the existing plant depends on trends in short run marginal costs, whereas an investment decision to construct new electrical plants depends on long run marginal costs. According to the results of the applied model, biomass fuel in the existing plants (comparison of SRMC) is more competitive than gas even with minimal biomass prices and no additional CO2allowance price or feed-in tariffs. With CO2prices larger than 26 €/t CO2, biomass becomes more competitive than gas and coal for its minimal price, while for its maximal price it is more competitive at CO2prices larger than 21 €/t CO2.
