摘要：This paper addresses issues related to greenhouse gas emissions in the European Union and measures to reduce them,in particular the European Emissions Trading Scheme (EU ETS).A model of the Polish electricity generation subsystem,taking into account EU ETS mechanisms,has been developed using the MARKAL optimization package.Data collected on the basis of available projects,regulations and statistics were entered into the model.The results of the modelling were used for formulating the following conclusions.Even the very high price of emission allowances (103 EUR/t CO2-eq) will not result in complete decarbonisation of the power sector by 2030.However,the allowance price levels will have a significant impact on the structure of electricity generation and the electrical power available in the system.Only high allowance prices will be an incentive to invest in renewable and nuclear energy based generation units.Power generation technologies with CO2 capture systems can be a chance to sustain the carbon economy while reducing emissions,but the problem will be the large-scale carbon dioxide storage.
