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.
