Core Viewpoint - The State Grid has announced a fixed asset investment plan for the "14th Five-Year Plan" period, with a total investment expected to reach 4 trillion yuan, representing a 40% increase compared to the previous period. This indicates a clear high-growth trend in China's power grid investments, leading to unprecedented market expectations for the "power grid cycle" [2]. Investment Dimensions - The power system can be divided into generation, transmission, transformation, distribution, and consumption. The investment in power grid projects can be categorized into three dimensions: trunk network/super high voltage, smart grid/digitalization, and distribution and consumption equipment [10]. - Trunk network/super high voltage investments focus on primary equipment for physical transmission channels, characterized by large single amounts and long construction cycles, typically requiring 2-2.5 years from approval to operation [10]. - Smart grid/digitalization investments pertain to secondary equipment, which includes control systems and automation, with shorter delivery cycles of 0.5-1 year and more stable revenue driven by both new line construction and upgrades of existing networks [11]. - Distribution and consumption side investments target distributed energy access and end-users, characterized by fragmented orders and fast turnover, with profits recognized in line with annual grid construction progress [11]. Company Analysis - Group A companies, such as Pinggao Electric and China XD Electric, exhibit strong cyclical performance linked to super high voltage construction, with profits closely tied to specific project completion timelines [13]. - Group B, represented by State Grid NARI, shows strong certainty and anti-cyclicality in its performance, driven by the increasing complexity of the power grid and technological premiums rather than direct dependence on grid investment fluctuations [15]. - Group C focuses on the end of the power grid, emphasizing access and consumption, with companies like Samsung Medical experiencing accelerated profit growth due to the shift from urbanization-driven to consumption-driven investments, particularly in response to the rapid growth of distributed solar energy [17]. New Power System Cycle - The current "14th Five-Year Plan" power grid cycle differs from previous ones, with its driving factors shifting from "scale expansion" to "reconstruction of the power grid under a new power system." The main challenge has evolved to system stability and capacity for renewable energy integration [20]. - It is anticipated that a significant portion of the 4 trillion yuan investment will be allocated to addressing the randomness and volatility of renewable energy sources. Key factors influencing the industry include cost fluctuations of raw materials, technological upgrades, investment policies, and supply-demand dynamics [20].
