Abstract: The present invention relates to a method of controlling a power plant, which power plant comprises: a boiler being adapted for combusting an organic fuel and for generating steam and a process gas comprising carbon dioxide; a steam system being; and a carbon dioxide capture system being adapted to remove at least a portion of the carbon dioxide from the process gas by contacting a carbon dioxide absorbent solution with the process gas, the method comprising: forwarding a portion of the steam produced by the power plant boiler to a regenerator of the carbon dioxide capture system; regenerating the absorbent solution in said regenerator through heating of said carbon dioxide absorbent solution by means of the forwarded steam; and automatically controlling the operation of the carbon capture system by means of at least one automatic controller. The invention also relates to a power plant including a carbon dioxide capture system.
