The global energy structure transition is entering a deep-water zone in 2026, leading to a systemic reconstruction of the fundamental logic of the gas turbine industry. As the "energy heart" supporting flexible grid regulation and high-reliability power output, gas turbines are irreplaceable core equipment in the modern industrial system. With the unprecedented demand for stable electricity from global AI Data Centers (AIDC) and China's independent development process advancing from "single-point breakthroughs" to "full-line breakthroughs," gas turbines are no longer merely power generation devices. They are transforming into the energy "ballast stone" of the digital era and a strategic pivot in the competition among major powers. Leveraging profound industry research expertise, Elephant Investment Advisors continues to focus on the direction of localization in the gas turbine industry, analyzing trends brought by the clean energy transition, with particular attention to the advancement of localization in core hot-section components and high-end manufacturing supply chains. This report, by dissecting the technical application practices of leading domestic enterprises such as Dongfang Electric Corporation and Shanghai Electric, explores key industry issues including high-temperature alloy materials, precision casting processes, and technical barriers, clarifying market profit models and value transmission pathways to provide a reference for establishing a valuation framework for the gas turbine industry for enterprises and investment institutions.
The logic of generational transition represents a high-efficiency leap from contemporary-class to advanced-class units. The generational evolution of gas turbines is essentially a continuous challenge to increase turbine inlet temperature and unit power output. The industry is currently in a transition period from contemporary-class (E/F) to advanced-class (G/H) and future-class (J) technologies. H-class units, with combined cycle efficiency exceeding 60%, significantly reduce fuel costs over the entire lifecycle and represent the core technological high ground for future large-scale combined cycle power plants and peak-shaving power.
Value chain distribution reveals the "barrier premium" of hot-section core components. By deconstructing the cost structure of gas turbines, the report identifies the extremely high commercial value of hot-section components (turbine blades, combustion chambers, turbine disks). These components must operate long-term under extreme conditions of high temperature, high pressure, and high centrifugal force, with their manufacturing processes and material science creating significant industry barriers. From the perspective of the total gas turbine cost value distribution, hot-section components not only represent a core part of the initial procurement cost but also contribute the majority of profits in the subsequent MRO (Maintenance, Repair, and Overhaul) phase. Turbine assemblies can account for up to 36% of the total unit cost, blades can account for 12%, and the remaining components account for 52%.
The reality of localization involves the "scissors gap" between the quantity of components and the total value replaced. The global gas turbine market is experiencing trillion-scale growth driven by both new units and services. The Chinese gas turbine market has a compound annual growth rate of 8.98%, yet gas-fired power generation accounts for only 3.2% of the total power generation structure, far below the global average, indicating substantial room for growth. Simultaneously, the localization process faces the challenge of "high quantity but low quality" replacement. Although the part count localization rate for F-class turbines has reached 90%, the overall value localization rate remains below 70%. The core challenge lies in the fact that high-value components like turbine blades, which account for up to 35% of the value, still rely on foreign technology. This "value scissors gap" highlights the urgency for the local supply chain to break into the high-end segment. Besides turbine blades (35%), other core components include cold-end casings (20.5%), control systems (18%), turbine disks (16.5%), and combustion chambers (10%).
Aftermarket opportunities lie in restructuring MRO services to break monopolies. Gas turbines exhibit a typical "long-tail effect," where lifecycle maintenance costs often exceed the initial purchase price. Furthermore, delivery lead times of up to 37 months and order backlogs stretching to 2030 provide original equipment manufacturers (OEMs) with a highly secure financial buffer. For a long time, global OEMs have monopolized the profitable technical service market through proprietary technical standards. However, with breakthroughs by domestic companies in hot-section component repair technologies and spare parts, China's trade deficit in gas turbines is continuously declining, falling from $462 million in 2022 to $279 million as of October 2024.
Future growth drivers include the engineering application of hydrogen co-firing and flexibility retrofits. The report provides a detailed analysis of the current competitive landscape of the gas turbine market. The global market exhibits an extremely concentrated oligopoly, where three giants—GE Vernova, Siemens Energy, and Mitsubishi Heavy Industries—hold the core share of the heavy-duty gas turbine market, leveraging deep technical expertise and global service networks. Within the domestic Chinese market, the competitive landscape is undergoing profound reshaping. The report indicates that the "Big Three" power equipment groups—Dongfang Electric, Shanghai Electric, and Harbin Electric—have established strong local competitiveness in the mainstream market for units like F-class through long-term technology introduction, absorption, and independent innovation. Concurrently, with the advancement of independent R&D projects, domestic companies are accelerating breakthroughs in core hot-section component manufacturing and aftermarket services, attempting to break the long-standing technological blockade by international giants.
