Performance and Cost Comparison NETL has completed a comprehensive study comparing the performance and cost of various fossil fuel-based power generation technologies, with and without carbon dioxide (CO 2) capture.Power generation systems investigated include integrated gasification combined cycle (IGCC), pulverized coal (PC), and natural gas …
However, current coal-fired power generation is in competition with renewable energy and thus generation has shifted in many countries from baseload to load following mode necessitating flexibility in power plant operations. As such, frequent cycling of coal-fired power plants can cause thermal and pressure stresses.

Central Java Power Project. Capacity: 2 x 950 MW. Notes: Originally the project was estimated to cost US$3.2 billion. In October 2013, Boy Garibaldi Thohir, president director of Adaro Energy, said that the cost of the project had risen significantly. Boy declined to state an exact figure but said that the total was not more than $5 billion.
Coal-Fired Power Plant Construction Costs 4 projected increase in cost "is consistent with other recent power plant project cost increases across the country."3 Nor are coal-fired power plants that are under construction immune to further cost increases. For example, Kansas City Power & Light just announced a 15 percent price

This raises the possibility that power plant developers will continue to follow the pattern of the 1990s and rely heavily on natural gas plants to meet the need for new power generation.! With current technology, coal-fired power plants using carbon capture equipment are an expensive source of electricity in a carbon control case.

Paul Breeze, in Power Generation Technologies (Second Edition), 2014. Cost of coal-fired power generation. Coal-fired power stations are relatively expensive to build since their construction involves both large quantities of expensive materials, such as iron and steel, and large volumes of labor. While some parts of a coal-fired power plant such as its steam turbines …
