中国银河证券曾韬: 海外AI产业链电力瓶颈显现 国内电力系统升级正当时
Core Viewpoint - The rapid growth of the global AI industry is leading to an explosive increase in computing power demand, which is causing power supply challenges in key regions like North America and Europe. Meanwhile, China's new energy-based power system construction is advancing, making the power sector a crucial investment focus under the dual guidance of stable growth and energy transition [1]. Group 1: AI Power Demand Surge - The expansion of AI computing power in North America and Europe is causing regional electricity shortages, impacting the construction progress of large data center projects. This issue is seen as a long-term structural contradiction rather than a short-term bottleneck [2]. - The energy consumption of AI data centers is increasing exponentially, while the backup capacity of European and American power grids is nearing exhaustion, compounded by transformer shortages and lengthy traditional grid upgrade cycles [2]. - The contradiction is reshaping the global AI industry chain layout, leading to three main trends: a shift of industrial geography to regions with abundant power resources, a fundamental change in power supply models towards integrated green power generation and storage, and accelerated technological evolution for improved energy efficiency [2]. Group 2: China's Advantages in Power Supply - China possesses significant advantages in power supply stability, scale, green power allocation capabilities, and efficiency in grid infrastructure construction. It has the world's largest unified power grid and a sufficient total power supply [3]. - The national strategy of "East Data West Computing" effectively connects the computing demand in the east with renewable energy-rich areas in the west, enhancing China's position in the global energy landscape [3]. - China's leading engineering capabilities and lower construction costs in ultra-high voltage transmission and renewable energy development provide a competitive edge in the global energy infrastructure market [3]. Group 3: New Power System Development - The construction of a new power system in China is entering a critical phase, with the main systemic bottleneck being insufficient "carrying capacity" and "flexibility" of the power system [4]. - The inherent randomness and volatility of renewable energy generation create significant challenges for grid peak regulation, leading to structural issues such as simultaneous "abandoning wind and solar" and "power shortages" in some regions [4]. - Future focus areas include the development of "active distribution networks" capable of massive access and intelligent control of distributed resources, the promotion of flexible DC transmission technologies, and the establishment of "virtual power plants" that aggregate distributed power sources, storage, and adjustable loads [4]. Group 4: Transformative Role of Energy Storage - Energy storage has transitioned from an optional component to a necessary element of the new power system, crucial for solving renewable energy consumption, ensuring grid safety, and enhancing efficiency [5]. - The business model for domestic energy storage is evolving from a single supporting model to a diversified revenue system comprising energy market revenues, capacity compensation, auxiliary service revenues, and special subsidies [5]. - National-level action plans are setting clear installation targets for energy storage and are focused on improving market mechanisms such as capacity pricing [5]. Group 5: Investment Opportunities in High-Growth Sectors - Under the dual policy guidance of "stabilizing growth" and "energy transition," the investment focus in the power and new energy sector is becoming clearer [7]. - In the short to medium term, opportunities exist in the export of grid equipment, domestic ultra-high voltage and main grid construction, and the storage sector, which is experiencing significant growth globally, particularly in large-scale storage and industrial storage in Europe and the U.S. [7]. - Long-term prospects remain strong in wind power, AI data center energy infrastructure, energy digitalization and intelligence, and emerging fields like space photovoltaics [7]. Group 6: Investment Strategy Focus - Current investment strategies should prioritize leading companies in various sub-sectors, as they possess comprehensive advantages in technology development, brand recognition, cost control, and overseas expansion capabilities [8]. - Leading companies are expected to strengthen their competitive edge in the context of high-quality industry development and "anti-involution" trends, while growth companies achieving breakthroughs in disruptive technologies should also be monitored [8].
