Industrial steam turbines are specialized turbine systems designed for industrial applications, including cogeneration, process steam production, and mechanical drive applications in industries such as chemicals, pulp and paper, and refining. The steam turbine market is expected to grow from USD 18.74 billion in 2025 to USD 22.48 billion by 2031 at 3.07% CAGR. Industrial steam turbines are essential for improving overall energy efficiency in industrial facilities through combined heat and power applications. The market is segmented by Capacity, Plant Fuel, and End-User Industry, with the industrial segment representing a significant share of the market.

The industrial steam turbines market is being reshaped by the repowering of ageing combined-cycle plants with advanced class steam turbines. Roughly 120 GW of F-class gas plants installed between 2000 and 2010 are reaching design life, driving a repowering cycle that replaces aging steam trains with H- or J-class equipment. A typical 500 MW uprate boosts net efficiency by 2-3 percentage points and extends asset life 20 years at 40%-50% of greenfield capex, yielding paybacks under seven years at USD 4 per MMBtu gas prices. European Union carbon-intensity rules encourage utilities to retrofit rather than build new, preserving existing grid permits and water rights. Vendors supplying modular turbine trains that fit within existing foundations have shortened outage windows from 16 weeks to 10, reducing lost-revenue risk for merchant plants. Hydrogen co-firing tolerance up to 30% by volume is now a bid prerequisite in several U.K. capacity-market tenders, further stimulating repower demand. However, the aggressive LCOE decline of utility-scale solar-plus-storage is creating competitive pressure, with four-hour lithium-ion storage paired with PV reaching a global weighted-average levelized cost of USD 56 per MWh in 2025. OEMs emphasize ancillary-service revenue and fast black-start capabilities to maintain market relevance. Power generation turbines will continue to evolve with advanced materials, digital monitoring, and hydrogen-ready designs, ensuring industrial steam turbines remain essential for efficient industrial operations.
