Market Scenario
Steam turbine market size was valued at USD 25.5 billion in 2025 and is projected to hit the valuation of USD 33.7 billion by 2035 at a CAGR of 2.8% during the forecast period 2026–2035.
Key Findings
In late 2025, the steam turbine market is robustly positioned as the "kinetic backbone" of the global energy transition, having successfully decoupled its long-term viability from fossil fuel dependency. The sector has pivoted from a volume-driven model to a value-driven one, where the primary currency is grid stability and operational flexibility rather than simple baseload generation.
Manufacturers have entrenched themselves in the industrial "behind-the-meter" segment, capitalizing on the surge in decentralized Combined Heat and Power (CHP) to insulate manufacturers from grid volatility. Furthermore, by integrating with carbon capture systems and converting aging assets into synchronous condensers, the market has secured a defensive moat against total electrification. This ensures that steam turbines remain indispensable for frequency control and reliability in high-renewable zones.
Looking toward the near future, the steam turbine market is projected to undergo a "bifurcated growth" phase through 2030:
Astute Analytica expect supply chains to verticalize further as OEMs mitigate geopolitical risks. This includes a marked increase in "regionalized" manufacturing hubs catering to the ruggedized needs of the Global South, while premium, high-efficiency metallurgy remains concentrated in advanced economies.

Tier-2 Rivals Weaponize Reverse Innovation to Slash Industrial Steam Turbine Pricing and Erode Western Market Share
For decades, the assumption was that Western OEMs in the global steam turbine market held an unassailable lead in metallurgy and aerodynamics. However, 2025 data suggests a dangerous erosion of this moat, specifically within the 50–150MW industrial steam turbine segment. State-owned enterprises from China and India have successfully pivoted from "copycat" engineering to "frugal innovation," creating a standardized turbine architecture that is undercutting premium OEMs by alarming margins.
According to the Global Power & Energy Statistics 2025 report released this quarter, Chinese exports of industrial steam turbines to Southeast Asia and Africa surged by 28% year-over-year. This captured $1.2 billion in market value that traditionally went to European Tier-1 players.
This disruption in the steam turbine market is directly linked to the physical manufacturing of the turbine. A teardown analysis by Power Engineering International reveals that these competitors utilize standardized, locally cast turbine casings that reduce capital expenditure (CAPEX) by 32% compared to Western bespoke designs. While the thermodynamic efficiency of these units trails premium models by approximately 1.5%, the 18-month payback period offered by these low-cost steam turbines is proving irresistible to price-sensitive industrial clients.
Thermal Battery Integration Creates a High-Margin Vertical for Steam Turbine Market Certified for Daily Deep Cycling
While traditional fossil fuel orders stabilize, a critical lifeline has emerged for the steam turbine sector through Long-Duration Energy Storage (LDES). The market is transitioning from "Fire-to-Steam" to "Storage-to-Steam," where molten salt and crushed rock thermal batteries rely exclusively on specialized steam turbines to discharge stored heat as electricity.
Data from the LDES Council’s Q3 2025 Update indicates that 12.4 GWh of thermal storage projects in the steam turbine market reached financial close this year. This created fresh demand for approximately 2.1 GW of "power block" steam turbines.
However, Sandia National Laboratories recently highlighted that steam turbines integrated with TES (Thermal Energy Storage) systems must endure daily "cold-start-to-full-load" ramp rates of 15% per minute—nearly double the stress profile of a conventional peaker unit. Consequently, manufacturers who have adapted their turbine control logic and valve metallurgy to handle these rapid enthalpy drops are winning. Recent tenders show a 15% price premium being awarded for steam turbines certified for "Daily Deep Cycling," confirming that the thermal battery sector is now a high-value vertical specifically for steam engineering.
Challenge: Democratized 3D Printing of Turbine Components Fuels a Gray Market Surge That Bleeds Billions from OEM Aftermarket Revenues
The most insidious threat to OEM profitability in the steam turbine market is the democratization of industrial additive manufacturing. The aftermarket—traditionally the cash cow for turbine manufacturers—is being cannibalized by Independent Service Providers (ISPs) utilizing high-resolution 3D scanning to reproduce proprietary turbine internals.
A 2025 alert from the American Society of Mechanical Engineers (ASME) notes that "Reverse Engineering" qualification standards have lowered the barrier to entry for non-OEM turbine parts. Consequently, the "Gray Market" for blades, seals, and diaphragms has grown to 18% of the total global aftermarket volume, up from just 6% in 2020.
ISPs in the steam turbine market are now offering delivery lead times of 14 days for complex steam turbine blade roots via laser sintering, compared to the 10-12 weeks typical of OEM supply chains. This agility is costing Tier-1 manufacturers an estimated $450 million annually in lost service revenue. Furthermore, with "Right to Repair" legislation expanding in the EU this year, legal protections for turbine IP are drying up, forcing OEMs to compete purely on logistics and pricing.
Trend: Grid Instability Monetizes Mechanical Inertia Driving a Massive Steam Turbine Retrofit Boom for Synchronous Condenser Conversions
As grids become saturated with inverter-based renewables, the massive rotating rotor of the steam turbine market has become a monetizable asset independent of steam generation. Smart Grid operators in high-renewable zones like Texas (ERCOT) and Australia (AEMO) are paying premiums for stability, leading to a decoupling of the steam turbine from the boiler.
The FERC 2025 Grid Reliability Report underscores a massive pivot: payments for "Synchronous Inertia" services have risen by 45% in the last twelve months. This has driven a retrofit boom specifically for steam turbines. We are seeing a surge in "Clutch-Enabled" turbine conversions, where the generator is physically decoupled from the steam turbine rotor to spin freely as a synchronous condenser when steam is unavailable.
In 2025 alone, 3.8 GW of coal-fired capacity underwent this modification, creating "Zombie Turbines" that generate revenue purely from inertia provision in the steam turbine market. The economics are compelling; average spot prices for inertia in South Australia hit $14/MWh-equivalent in Q3 2025. Competitors offering steam turbines with integrated SSS clutches are capturing 60% of Life Extension (LEX) contracts, proving that the turbine’s physical weight is becoming as valuable as its megawatt output.
A Flood of Refurbished Steam Turbines Creates a Secondary Market That Caps Pricing Power for New Industrial Orders
Finally, we must address the "Asset Relocation" phenomenon affecting new steam turbine sales. The aggressive decommissioning of coal assets in the West has flooded the market with high-quality, mid-life turbine units. Instead of being scrapped, these steam turbines are being refurbished and exported to developing markets.
According to Global Energy Monitor, over 3.5 GW of steam turbine capacity was relocated from the EU/USA to steam turbine markets in Central Asia and South America in 2025. This "Secondary Market" is pricing 20-year-old Siemens and GE steam turbines at roughly USD 120,000/MW including refurbishment), drastically under cutting the USD 450,000/MW price tag of a new build unit. This trend is effectively capping the price ceiling for new industrial steam turbines. For every "Certified Pre-Owned" turbine installed, a new order is lost.
