Grid Constraints and Policy Tailwinds Drive a New Era of AIDC Power

Overview

Based on an expert conference call regarding AIDC (Artificial Intelligence Data Center) onsite power generation solutions, this report maps out the power supply chain for the next phase of global data center infrastructure construction. The core conclusion is that US grid constraints and Chinese policy tailwinds are jointly driving data center power from a grid-dependent model to a new era of onsite power generation. In this context, the report favors Chinese suppliers capable of providing integrated solutions such as gas engines, gas turbines, and SOFCs (Solid Oxide Fuel Cells). It explicitly maintains 'Overweight' ratings for Weichai Power and Yingliu Electromechanical, identifying them as core beneficiaries of this global trend.

Core views

Demand Side: Grid bottlenecks are the primary driver behind the surge in onsite power demand. Experts point out that while power demand for US data centers continues to soar, grid interconnection delays and energy shortages are directly impacting project timelines and investment decisions. Consequently, data center operators are increasingly turning to onsite solutions like gas turbines, gas engines, and SOFCs to fill power gaps and ensure reliable, scalable power supply. According to expert estimates, although about 60% of US data centers still rely on the grid, over 20% already use gas turbines as their primary power source, with the share of gas engines and SOFCs rising rapidly. Technology Route: SOFC is emerging as a highly competitive solution, with Chinese policy support as a key catalyst. The report believes that the lifecycle cost of SOFC (currently $0.08-0.15/kWh) is expected to decline further with scaling and localization. Its flexibility, lower operating temperatures, and fast start-stop capabilities are increasingly valued by data center customers. Experts predict global SOFC demand will reach 20-30GW by 2030. Active support from the Chinese government, similar to the early stages of the lithium battery and solar industries, will drive further expansion of the TAM (Total Addressable Market) and bring profit margins to leading enterprises. Competitive Landscape: The industry trend is shifting from single products to integrated full-stack solutions, a key advantage for leading players. Although South Korean marine engine manufacturers have won some orders, their impact is limited due to high costs, long delivery cycles, and insufficient supply chain flexibility. The report believes that while global power shortages by 2030 will create sufficient demand space, Chinese suppliers are most likely to capture market share due to their advantages in scale, supply chain, and delivery speed. Company Analysis: Weichai Power and Yingliu Electromechanical represent two clear investment themes. Weichai Power's growth engine lies in the rapid ramp-up of its AIDC engine and SOFC capacity. The report forecasts its 2026 AIDC engine shipments to reach 3,500-4,000 units and highlights its ambitious SOFC capacity plan: 30MW in 2026, 200MW in 2027, 600MW in 2028, reaching 1GW by 2030. The low operating temperature and fast response of its SOFC technology are core competencies, and its integrated data center power solutions (combining gas engines, SOFC, and energy storage) are gaining customer recognition globally. Yingliu Electromechanical's growth is clearer, with overseas gas turbine demand being its most definite near-term growth driver. Order visibility is continuously improving among customers like Siemens Energy and Baker Hughes. Meanwhile, the MRO (Maintenance, Repair, and Overhaul) business offers higher margins compared to new component manufacturing. Increased domestic localized procurement and state-owned enterprise orders constitute a second growth curve. Additionally, its aero-engine business is expected to start contributing more meaningful revenue in FY27E-FY28E.

Analysis framework

The report employs a research method combining 'expert interviews + industry logic deduction + individual stock fundamental analysis'. First, by organizing a high-quality expert conference call, it obtained first-hand industry insights on data center power demand, technology choices, and competitive dynamics, providing a factual basis and logical starting point for the report's views. Next, the report unfolds along the main line of 'demand drivers → technology paths → competitive landscape → investment targets'. It first identifies the core contradiction—grid bottlenecks—and uses quantitative data (e.g., 60% reliance on the grid, 20% using gas turbines) to substantiate the certainty of the trend. Then, the report focuses on analyzing SOFC as an emerging technology path, arguing for its competitive advantages and future potential from multiple dimensions such as cost curves, policy support, and technical characteristics. This analytical framework is akin to judging whether an industry is in the early stage of a policy-driven 'penetration S-curve'. In the competitive analysis, the report not only points out the trend towards integrated solutions but also demonstrates the comparative advantages of Chinese players by contrasting Chinese suppliers with South Korean marine engine manufacturers in terms of cost, delivery time, and supply chain. Finally, the report maps industry logic to specific targets. For Weichai Power, it focuses on concrete data regarding capacity expansion to verify its execution and growth potential. For Yingliu Electromechanical, it clearly showcases its diversified growth path by breaking down the different drivers of its overseas and domestic businesses, and uses valuation tables for horizontal comparison to highlight its high-growth characteristics.

Methodology notes

• Industry/Sector Analysis FrameworkSupply and Demand Framework

  By analyzing the contradiction between the demand side (surging AI data center power demand) and the supply side (grid interconnection delays and power shortages), the report argues for the urgency and market space of onsite power generation solutions.

  This is a basic industry analysis method, focusing on the supply-demand gap. In this report, demand (data center power needs) is growing rapidly, but supply (grid transmission capacity) cannot keep up. This gap creates a new market opportunity for onsite power generation.

• Industry/Sector Analysis FrameworkPenetration S-curve

  The development stage of SOFC technology is analogized to the early stages of the lithium battery and solar industries, implying it is in the initial acceleration phase of the 'penetration S-curve' under policy support, with huge future growth potential.

  The Penetration S-Curve describes the process of a new technology from market introduction to rapid growth and then maturity. By comparing SOFC to early-stage lithium batteries and photovoltaics, the report suggests it is on the eve of explosive growth driven by policy, representing a key window for investment布局 (positioning).

• Industry/Sector Analysis FrameworkVolume-Price Split

  In the analysis of Weichai Power, the report specifies its AIDC engine shipment volume (3,500-4,000 units) and SOFC capacity plans (30MW-1GW). This is a typical 'volume' split, which is core to predicting its future revenue growth.

  Volume-price split is a basic method for analyzing the sources of a company's revenue growth, breaking it down into 'how much was sold' (volume) and 'at what price' (price). The report quantifies Weichai Power's future growth path by tracking its explicit capacity and shipment plans.

• Industry/Sector Analysis FrameworkUpstream-Midstream-Downstream Transmission

  The report analyzes the transmission logic from downstream demand (data center operators) to midstream equipment (onsite power systems) and then to upstream key component suppliers, thereby identifying investment opportunities for Yingliu Electromechanical as a key component supplier.

  This analysis method emphasizes finding beneficial links along the industrial chain. When terminal demand explodes, profits transmit along the chain. The report not only sees Weichai, which makes complete machines, but also Yingliu, which provides key components for gas turbines, demonstrating a comprehensive grasp of the industrial chain.

• Competition and Strategy FrameworkMoat / competitive advantage

  By comparing Chinese suppliers with South Korean competitors in terms of cost, supply chain, and delivery speed, the report argues for the competitive advantages of Chinese players, i.e., their 'moat'.

  A moat refers to advantages a company can maintain long-term that are difficult for competitors to imitate. The report believes that Chinese suppliers' capabilities in scale, cost control, and fast delivery constitute a 'moat' compared to South Korean rivals, making them more likely to succeed in global competition.

• Valuation MethodPE/PEG valuation

  In the valuation comparison table, the report lists the P/E (Price-to-Earnings) and PEG (Price/Earnings-to-Growth) ratios of various companies for horizontal comparison of valuation levels and growth cost-effectiveness.

  P/E looks at how many times earnings the current stock price represents, while PEG divides P/E by the earnings growth rate to measure the price paid for growth. By comparing, the report finds that the PEGs of Weichai Power and Yingliu Electromechanical are far lower than those of overseas peers, suggesting their high growth is not fully priced in, offering better value.
