Global trends are moving towards sustainable power production, with focus on renewable energies for climate management. However, coal remains a significant source of fossil fuel for power generation supplying a third of all energy used worldwide and making up 40% of electricity generation. Coal power plant are designed in such a way that certain components can be replaced, extending the life of the power plant and improving performance. Although some of the coal fired power plants have reached mid—to-end of life phases of their lifecycle, utilities that operate them are unlikely to decommission them because of the increase in power demand brought on by industrialization. Repowering is an intervention that can be instituted to get them to continue running economically for more years. It is preferred over construction of new plants because of reduced turnaround time and lower cost of construction. This paper presents a literature review on overall benefits that can be derived from repowering coal power plants that were commissioned in the 20th century. It offers repowering as an alternative, providing cleaner coal power production solutions to utilities that cannot immediately do away with coal power but need improved plant performance in a short space of time.
