Gas turbine plants are energy generation facilities that use high-temperature, high-pressure combustion gases to drive turbine blades and produce electricity. The design is based on the Brayton cycle, where air is compressed, mixed with fuel, ignited, and expanded to rotate the turbine. These plants emerged as a major power solution in the mid-20th century when rapid electrification, industrial expansion, and the need for flexible and fast-starting power systems became essential. Today, they remain widely used in energy grids, industrial facilities, and aviation-linked power systems due to their high power-to-weight ratio and operational reliability.
Gas turbine plants can operate as simple-cycle units or as part of combined-cycle systems where waste heat is used to produce additional electricity. Their ability to adjust load quickly makes them suitable for balancing renewable energy sources such as solar and wind. The development of advanced materials, cooling techniques, and low-emission combustion chambers has significantly improved their performance.
