Summary of Conference Call Notes Industry Overview - The backup power supply application for data centers has shifted from traditional IDC to intelligent computing AIDC since 2013, with diesel generators being essential and no alternatives available [1] Market Demand and Supply Shortage - Major data center markets are in the US, China, and Southeast Asia, with US orders extending to 2027 due to limited production capacity of large international engine brands [2] - Diesel generators account for a small portion of these companies' overall business, leading to a supply shortage in the domestic market, where local internet companies prefer imported engines due to performance gaps [2][3] Pricing Trends - Current market shortages have led to price increases, with 2MW models priced over 2 million, and customers willing to pay an additional 200,000 per unit [3] - Domestic diesel generator sets are approximately 400,000 cheaper than those using foreign engines [3] Engine Manufacturers and Supply Situation - Cummins has imported only 60 units to China over 25 years, primarily for self-use [4] - MTU has supplied around 800 units to China, with a joint venture producing 300-400 units [4] - Domestic manufacturers like Yuchai and Weichai have a maximum annual capacity of about 1,000 units each for large power engines [7] Market Dynamics - The demand for 2MW units is expected to reach around 3,000 units in 2024, with significant growth anticipated in the second half of the year as internet giants shift from leasing to self-built data centers [18] - Major players in the backup power industry include imported brands like Caterpillar, Cummins, MTU, Kohler, and Mitsubishi, alongside domestic companies like KOTAI, Taihao Technology, and Sumida [14] Future Outlook - The supply of imported engines is unlikely to increase, which may benefit domestic manufacturers if they can validate their engines [19] - The market share of domestic manufacturers like Weichai and Yuchai may increase due to the shortage of imported engines [18] - The price of imported engines is expected to rise by 3-5% annually, with generator sets potentially increasing by 10-15% due to rising costs [26][27] Technical Considerations - The performance of domestic engines is currently perceived as inferior, with issues like oil and water leaks being common [23] - The requirement for redundancy in configurations may affect the cost-effectiveness of using domestic engines [23] Key Players' Market Share - KOTAI, Taihao, and Sumida each hold approximately 15% market share, while foreign brands dominate the rest [18] - The total market demand for 2MW units is projected to be around 3,000 units, with a significant portion of this demand coming from major internet companies [18] Conclusion - The backup power supply market for data centers is experiencing significant growth driven by the shift to AIDC, with supply constraints leading to price increases and a potential shift in market share towards domestic manufacturers if they can meet performance standards [1][2][18]
