Influence of chosen parameters on economic effectiveness of a supercritical combined heat and power plant

The article presents an economic analysis of a supercritical combined heat and power plant integrated with a carbon dioxide chemical absorption unit. The authors describe first the thermodynamic performance boundaries that result from the integration with a carbon capture unit as a function of its heat and electric power consumption rate. These limits refer to the heat and electric power annual production which is essential in the economic analysis. Secondly, the influence of a set of different parameters on the break-even price of electricity is studied. The main focus for examination is the effect on the break-even price of electricity of: carbon dioxide emission allowance price, fuel price, investment costs, overhaul and other maintenance costs.
