Core Insights - The overall judgment indicates that both domestic and overseas AI-driven demand will continue to grow, leading to stock price performance in the AIDC industry. The overseas market, particularly in the U.S., is experiencing tight supply and demand for power equipment, which presents opportunities for domestic supply chains to expand internationally. Additionally, domestic capital expenditure on power grids is steadily increasing [3]. AIDC Power Supply: Continuous Beta and Clear Industry Trends - The capital expenditure of major overseas cloud service providers (CSPs) is expected to continue increasing, driving high demand for AIDC. The total capital expenditure of the four major overseas CSPs (Amazon, Google, Microsoft, Meta) is projected to grow at rates of 34% in 2021, 20% in 2022, -7% in 2023, and 55% in 2024, with a significant increase of 71% in the first three quarters of 2025 [11]. - Domestic CSPs have also seen a resurgence in capital expenditure, with a staggering 184% year-on-year growth in 2024 and 87% in the first three quarters of 2025 [13]. - The power consumption of AI servers is expected to rise significantly, with cabinet power levels projected to exceed 200kW in the near future, indicating a need for technological upgrades in both internal and external power supplies [20][25]. - The transition from three-level to two-level voltage reduction in internal power supplies is anticipated, which will streamline power supply processes [28]. - External power supplies are shifting from UPS to HVDC and SST solutions, reflecting a clear trend towards direct current and medium voltage systems [32]. Power Equipment Export: Continuous High Demand - The U.S. has seen a rapid increase in new power installations since 2020, with growth rates of 1.20%, 2.42%, 0.98%, 2.14%, and 3.47% from 2020 to 2024, indicating a robust demand for power equipment [59]. - China's transformer exports reached 46.5 billion yuan in the first nine months of 2025, marking a 40.20% year-on-year increase, with other power equipment exports also showing significant growth [77]. Domestic Power Grid: Continued Investment and Recovery - The approval of ultra-high voltage direct current projects is progressing steadily, with a rich pipeline of projects expected to drive growth during the 14th Five-Year Plan [81]. - The total bidding amount for power grid projects has reached 78.7 billion yuan, reflecting a nearly 20% year-on-year increase, significantly surpassing the 7.61% growth rate of 2024 [84]. - The domestic smart meter replacement cycle is expected to smooth out, with a projected increase in bidding quantities in 2026-2027 as new standards are introduced [90].
