The global gas turbine market size was estimated at USD 11.0 billion in 2024 and is projected to reach USD 14.2 billion by 2033, growing at a CAGR of 2.7% from 2025 to 2033. A gas turbine, also known as a combustion turbine, is a type of engine that generates mechanical energy by heating a mixture of fuel and external air to extremely high temperatures. This process causes the turbine blades to spin, converting thermal energy into mechanical motion.

The mechanical energy produced by the spinning turbine is then used to drive a generator, which subsequently converts it into electrical energy. The increasing adoption of advanced technologies within the energy sector, alongside a growing preference for distributed power generation systems, is significantly driving the expansion of the gas turbine market. The industry's forward momentum is further supported by enhanced government initiatives and incentives promoting cleaner energy solutions aimed at reducing carbon dioxide (CO₂) emissions globally.

Gas turbines are predominantly utilized in power generation applications, where they play a vital role in ensuring efficient and reliable electricity supply. In many industrial settings, operating a simple cycle gas turbine power plant can be more cost-effective than purchasing electricity from external sources. However, in pursuit of greater efficiency, combined cycle power plants are often favored. These plants utilize the waste heat from gas turbines to power a steam turbine, thereby maximizing energy output.

An example of this is the Combined Heat and Power (CHP) plant, a type of combined cycle power system that produces both electricity and useful mechanical energy, often in the form of heating. CHP systems enhance overall efficiency and energy utilization, making them highly desirable for industrial and commercial use.

Another key driver of market growth is the global transition from coal-based to gas-based power generation, particularly in major economies such as the United States, Japan, India, and China. These countries are increasingly adopting natural gas as a cleaner alternative to coal in their power generation mix. In addition, supportive government policies and investments aimed at constructing and upgrading gas-based power plants are reinforcing this shift and further contributing to the expansion of the gas turbine market.

Key Market Trends & Insights:

• In 2024, the Asia Pacific gas turbine market accounted for the largest share of the global market, representing 37.15% of the total market share. This dominant position can be attributed to rapid industrialization, growing energy demand, and substantial investments in power generation infrastructure across countries such as China, India, Japan, and Southeast Asian nations. Government initiatives aimed at reducing carbon emissions and increasing reliance on cleaner energy sources like natural gas have further fueled the adoption of gas turbines in the region.

• From a technological standpoint, the Combined Cycle segment emerged as the leading technology in 2024, capturing the highest market share of 87.78%. Combined cycle technology is widely favored for its high efficiency and cost-effectiveness, as it utilizes both gas and steam turbines in a single cycle to maximize energy output from the same fuel source. This makes it an ideal choice for large-scale power plants and utilities seeking improved fuel efficiency and reduced emissions.

• In terms of capacity, the >200 MW segment held the highest market share in 2024. Gas turbines in this capacity range are typically used in large-scale power generation projects, especially for national grids and industrial power plants. Their ability to generate a significant amount of electricity efficiently makes them a preferred option for meeting the high energy demands of urban centers and industrial hubs.

• Based on end-use, the Power & Utility segment dominated the market in 2024, holding the highest share among all end-use categories. This is primarily due to the extensive use of gas turbines in electricity generation for public utility services, where they serve as both primary and peaking power sources. The segment benefits from continuous demand for reliable and efficient electricity, especially in regions with rapidly expanding urban populations and industrial activity.
