Analysis of Levelized Cost of Energy for 660 MW Thermal Power Units under CCUS Application

In order to study the changes in levelized cost of energy and the cost of electricity supply after the CCUS (Carbon Capture, Utilization and Storage) retrofit of coal-fired power station, the current development trend of the electricity-carbon market was summarized and analyzed, and a simulation model was built to show the cost and benefit of CCUS application for coal-fired power station. A sensitivity analysis was carried out using the cost of carbon capture and carbon trading price as variables. It is predicted that levelized cost of energy will fall to the range of 20% upward fluctuation of the regional coal trading benchmark price between 2034 and 2035. After 2039, the rate of change of levelized cost of energy before and after the transformation will be negative, which means that levelized cost of energy after transformation will be lower than the target of levelized cost of energy before transformation. In addition, the carbon capture cost and carbon trading price will have a different impact on levelized cost of energy and power supply cost, but they will both show good economic results in the future.
