Summary of Key Points from the Conference Call on US Power Transformers and AIDC Electrical Systems Industry Overview - **US Power Transformer Market Dynamics**: The US power transformer market is experiencing a significant supply shortage, with order lead times extending to 3-4 years. This has led utilities and data center operators to consider non-traditional suppliers from regions such as Brazil, Eastern Europe, China, Korea, South America, and Turkey. The local US capacity is projected to meet only about 40% of domestic demand despite aggressive expansion plans [7][18][20]. - **Market Size and Growth**: The power transformer market size was approximately USD 2 billion in normal years before COVID-19, which halved to around USD 1 billion in 2020 due to procurement delays. By the end of 2022, the market rebounded to USD 2-2.5 billion, with projections for 2023/2024 reaching USD 3-4 billion, and an expected growth to USD 5.5-6 billion by 2025, primarily driven by data centers [8][10]. Key Trends in AIDC Electrical Systems - **Transition to 800V DC Architecture**: The rising power demands of AI are necessitating a shift to 800V DC architecture in new AI data centers. This transition is expected to incur a 10-20% capex premium but is deemed essential for managing higher rack densities [2][23][24]. - **Power Backup Evolution**: There is a shift from centralized uninterruptible power supply (UPS) systems to decentralized battery backup units (BBUs), with UPS systems converging with battery energy storage systems (BESS). The long-term solution is the development of solid-state transformers (SST) that convert medium voltage directly to 800V DC, although widespread adoption is contingent on proving reliability [2][23][27]. Investment Recommendations - **Stock Recommendations**: - **Buy Kstar**: Increased order visibility for ODM partnerships in UPS products for AIDC projects in North America, with a target price raised to RMB 55.4 [3]. - **Buy Hongfa**: Expected AIDC-related revenue of RMB 700-800 million in 2024, benefiting from rising 800V DC relay applications due to its 50% global market share [3]. - **Neutral on Sungrow**: Concerns regarding the attractiveness of solar + BESS solutions and the reliability of SST for widespread adoption [3][6]. Supply Chain and Manufacturing Insights - **Manufacturing Capacity Constraints**: The US electrical equipment market is growing faster than local manufacturing capacity, prompting global brands to seek contract manufacturing partnerships with non-US suppliers, including those from China [2][29]. - **Pricing Trends**: Prices for medium transformers range from USD 2-5 million, while large power transformers can exceed USD 10 million. Overall, prices have more than doubled since 2020 due to supply-demand imbalances and raw material inflation [17][18]. Challenges and Risks - **Execution Risks**: High execution risks are present due to skilled labor shortages in the US, with companies like Siemens Energy falling behind on expansion schedules. Material constraints, such as reliance on a single domestic core steel supplier, also pose significant challenges [19][20]. - **Backlog Cancellation Risks**: There are currently no cancellations of existing orders in favor of Chinese suppliers; instead, new projects requiring faster delivery are being awarded to them. Some manufacturers require down payments to reserve production slots, indicating a cautious approach to managing order backlogs [21][20]. Conclusion The US power transformer and AIDC electrical systems market is undergoing significant changes driven by rising demand from AI data centers and a shift towards more efficient electrical architectures. Investment opportunities exist in companies like Kstar and Hongfa, while challenges related to supply chain constraints and execution risks remain critical considerations for stakeholders in the industry.
