摘要： A power plant system can comprise a first gas turbine having a first efficiency to produce a first exhaust flow, a first electrical generator driven by the first gas turbine, a first heat recovery steam generator to receive the first exhaust flow and generate a first steam flow, a second gas turbine having a second efficiency less than the first efficiency to produce a second exhaust flow, a second electrical generator driven by the second gas turbine, and an exhaust gas conditioning device to reduce temperature of the second exhaust flow, a steam turbine driving a steam electrical generator to receive the first steam flow. The second gas turbine can be selectively operated to generate electricity with the second electrical generator under peak loading conditions when a sum of output from the steam electrical generator and the first electrical generator are less than an electrical demand from a grid.
