Combined cycle power plants are common because of their high efficiency and scalability. They typically combine a gas turbine cycle (the Brayton Cycle) with a steam turbine cycle (the Rankine Cycle) [1]. The goal of this project is to determine the operating efficiency and profitability of a realistic combined cycle power plant. The power plant is as follows: 1.
