A system for a power generation plant includes a boiler having a superheater, a first header fluidly coupled to an outlet of the superheater and being configured to receive steam from the superheater, a turbine elevated to a location generally adjacent to the outlet of the superheater, and a main steam piping system extending from the first header to the turbine and being configured to direct a flow of the steam from the first header to the turbine. The system further includes a flexible portion upstream from the first header operative to flex with respect to the first header and the boiler due to a thermal displacement of the boiler.
