Description of a modern design of 65 MW impulse steam turbine is presented in the paper. The construction of the turbine makes use of own highly-loaded profiles, which allow reducing the total number of stages and locating the entire flow system in one casing. The a/m turbine has been designed and manufactured at the ALSTOM Power Elbląg Design Office and applied in practice to the combined cycle unit at Zielona Góra Heat and Power Station (H&PS). The performed heat measurements confirmed the guaranteed high performance.
