A heat recovery steam generator (HRSG) is a heat exchanger system used in power plants, particularly combined-cycle power plants, to recover waste heat from gas turbine exhaust gases and convert it into steam. This steam is then used to drive a steam turbine or for process heating, significantly improving overall plant efficiency. The primary purpose of an HRSG is to maximize energy efficiency by capturing and reusing exhaust heat that would otherwise be wasted.
The heat recovery steam generator market consists of sales by entities (organizations, sole traders and partnerships) of heat recovery steam generator that are widely used by power producers and industrial operators seeking to improve energy efficiency, reduce fuel costs and lower greenhouse gas emissions by making productive use of heat that would otherwise be lost to the environment. The key users of HRSGs include utilities operating combined cycle power plants, industrial facilities in chemicals and refineries, pulp and paper mills and other large energy-intensive manufacturing operations; these end users integrate HRSGs as part of their broader energy infrastructure where both electricity and steam are needed simultaneously.
The global heat recovery steam generator market was valued at $1,325.8 million in 2020 which grew till 2025 at a compound annual growth rate (CAGR) of more than 6.00%.
Rising Use Of Low-Carbon And Alternative Fuels In Power Generation
During the historic period, the heat recovery steam generator market was significantly driven by the rising use of low-carbon and alternative fuels in power generation. As power producers transitioned away from high-emission fuels, there was an increased emphasis on maximizing the energy extracted from cleaner fuel sources to achieve optimal efficiency and cost-effectiveness. HRSGs became a critical component in this transition by enabling waste heat recovery from gas turbines and other fuel-flexible systems, thereby improving overall plant efficiency while maintaining lower emissions intensity. For instance, according to New OECD (Organisation for Economic Co-operation and Development), an intergovernmental organization with 38-member countries and International Energy Agency (IEA), a Paris-based autonomous intergovernmental organization, data, in 2024, most government support for fossil fuels continued to go to consumption, accounting for 84% of the total fiscal cost. Support generally declined across sectors, except for support for fossil fuel use in transport, which increased slightly from $112 billion in 2023 to $114 billion in 2024. Therefore, the heat recovery steam generator market was significantly driven by the rising use of low-carbon and alternative fuels in power generation.
Integration Of Digital Monitoring And Performance Optimization Technologies Into The Market Systems
Key players operating in the heat recovery steam generator market are focusing on integrating digital monitoring, advanced control and performance optimization technologies into HRSG-equipped combined cycle assets. These solutions typically use real-time data trending, analytics and artificial intelligence (AI) to optimize heat recovery performance, reduce unplanned outages and help operators maintain efficiency under flexible cycling and varying load conditions. For instance, in October 2025, Mitsubishi Power, a Japan-based power solutions brand of Mitsubishi Heavy Industries, Ltd. (MHI), a subsidiary that specializes in gas turbines, steam turbines, HRSGs, implemented its TOMONI remote monitoring solution at Thailand's Sriracha and Pluak Daeng gas turbine combined cycle (GTCC) plants under a 25-year long-term service agreement (LTSA), where each power train includes an HRSG, highlighting how OEM service partnerships are increasingly bundling digital monitoring and optimization capabilities to enhance HRSG-based combined cycle performance.
The global heat recovery steam generator market is concentrated, with large players operating in the market. The top 10 competitors in the market made up 45.1% of the total market in 2024.
