Summary of Conference Call Records Industry Overview - The focus is on the **diesel generator (柴发)** sector and its relevance to the **data center** industry, which is expected to see a significant increase in power demand, with new loads projected to exceed **100 GW** by **2030** at a **CAGR of over 30%** [1][2]. Key Points and Arguments Diesel Generators and Market Dynamics - The market is optimistic about diesel generators due to five main reasons: 1. Natural gas internal combustion engines are gradually entering the primary power market. 2. Diesel generators are transitioning from backup to primary power sources in specific scenarios. 3. Geopolitical conflicts, such as the US-Iran conflict, have increased demand for backup and emergency power sources. 4. Domestic suppliers are seizing critical opportunities to expand overseas. 5. Channel reuse and technological extension capabilities are providing new growth avenues for domestic suppliers [2]. Power Supply Shortages - The supply of primary power sources is currently tight, with gas turbines' production scheduled until **2030-2031**, exacerbating the demand gap for primary power. This situation is driving the need for alternative power sources, including natural gas internal combustion engines and diesel generators [3][4]. Geopolitical Impacts - Geopolitical tensions have significantly increased the demand for diesel generators as backup and emergency power sources. The modular transport and rapid deployment advantages of diesel generators have highlighted their strategic value in conflict and post-disaster reconstruction scenarios [4]. Domestic Suppliers' Opportunities - Domestic OEM suppliers are beginning to receive inquiries from the Middle East, and as overseas suppliers face extended delivery times, domestic suppliers are entering a critical window for overseas market access. This expansion is expected to enhance profit margins due to tighter supply-demand dynamics in international markets [4][5]. Technological Pathways - Diesel generators have a high degree of technical irreplacability in backup power applications. Despite the presence of alternative technologies, diesel generators are expected to maintain their role as reliable backup power sources over the next **3-5 years** [7]. Liquid Cooling Technology and AI Hardware Trends in Liquid Cooling - The rise in power density within server cabinets is driving the development of liquid cooling technologies. The transition from **800G** to **1.6T** optical modules is expected to increase the penetration of liquid-cooled optical interfaces, with their value rising from several tens to hundreds of yuan, representing a nearly **10-fold increase** [1][8]. Challenges in Southeast Asia - Domestic AI hardware suppliers expanding capacity in Southeast Asia face challenges related to labor efficiency and equipment precision. To address these issues, suppliers are automating production processes, particularly in testing, dispensing, and surface mounting, leading to increased orders for automation equipment [9]. Conclusion - The diesel generator market is poised for growth driven by increasing power demands in data centers and geopolitical factors. Domestic suppliers are well-positioned to capitalize on these trends, while advancements in liquid cooling technology present new investment opportunities. The challenges faced by AI hardware suppliers in Southeast Asia highlight the need for automation and efficiency improvements in production processes.
