In this study, Turkey and the main countries with high capacity of Coal Fired Thermal Power Plants (CTPPs) installation capacity in the world were examined. Related parameters such as installed power values, energy production values and capacity factors in these countries are also discussed. These parameters in the countries that stand out in coal-based electrical energy production have been evaluated over the years and projection studies have been carried out. By making these projection studies, predictions about the future of CTPPs can be tried easily to be made. Analysis results are indicated and interpreted with figures and tables. In addition, capacity utilization rates, which is an important parameter in terms of efficient operation and age of coal-based thermal power plants, were also examined firstly. According to these results of the analysis, the country with the highest capacity ratio was determined as Japan with a value of around 90%. Today, with the emergence of the energy crisis, depending on the re-emergence of coal, energy production planning and projection studies gain strategic importance for every country. Country-based projection studies for CTPPs are insufficient and limited in the literature. With this projection study, predictions were made for the development of CTPPs on the basis of countries and around the world and contributed to the studies in the literature in this field.
