Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control global warming. Competitiveness of power plants designed for CO2 capture and compression, retrofit ready power plants and efficient ways to retrofit conventional power plants to CO2 capture plants will allow earlier utilization of CO2 capture systems (12). The objective of the present invention is to provide a fossil fired power plant with minimum impact of the CO2 capture system (12) on the conventional part of the plant as well as a method to operate such a plant. Further, a power plant, which is ready for the retrofit of a CO2 capture plant and a method of retrofitting an existing plant into a power plant with CO2 capture as well as a method to operate this kind of plant are the object of the invention. One main aspect of the invention is to add a power plant part, which is capable of providing the steam and power required to operate CO2 capture system (12), and to provide a CO2 capture system (12), which has the capacity to remove CO2 from the flue gas flows of the conventional, and of the additional power plant part.
