A design for competition (DfC) method using the attractiveness criteria has been proposed for the power equipment market. It is noted that the method is more general compared with the DtC (Design to Cost) method traditionally used by OEMs. The application of DfC with the attractiveness criteria for design of steam turbines with separate and combined high and medium pressure cylinders is presented. It is shown that it is expedient to use structural schemes of turbines with combined cylinders with the parameters increasing to reach and exceed the supercritical region values for a unit capacity of 600 MW (including the existing technical limitations).
