The main advantages and disadvantages of single- and twin-shaft CCPPs are analyzed, taking into account various configurations and thermal efficiency and controllability. Single-shaft configurations with and without freewheeling clutch between the electric generator and the steam turbine are considered. Single-shaft 370 – 420 MW CCPPs operated in Russia are compared with twin-shaft units of the same capacity.
