Core Viewpoint - The global power system is facing new challenges, leading to an increased demand for grid expansion and upgrades, which is expected to directly benefit the power equipment industry [1] Group 1: Main Grid Developments - The demand for ultra-high voltage (UHV) construction is increasing due to the growth of inter-provincial electricity flow and the pressure of renewable energy consumption. As of December 2024, China has built and put into operation 41 UHV transmission lines, including 20 AC lines and 21 DC lines [2] - During the 14th Five-Year Plan period, China is expected to start construction on "three AC and nine DC" UHV lines, with over 20 lines anticipated to be operational in the 15th Five-Year Plan period, which will boost demand for related equipment [2] - Flexible DC technology is expected to become mainstream due to its advantages in large-scale renewable energy transmission, especially as the prices of core components like IGBT decrease. Investment in this area is projected to reach 380 billion yuan from 2021 to 2025 [2] Group 2: Distribution Network Developments - Both domestic and international plans for distribution network upgrades are expected to increase demand for transformers. China emphasizes high-quality development in distribution networks, while the EU plans to invest 584 billion euros for grid modernization [3] - China's transformer production accounts for 35% of the global market, and with overseas production facing constraints, there is an opportunity for Chinese companies to benefit from rising global demand [3] Group 3: Investment Recommendations - The emergence of new electricity consumption scenarios, represented by computing power, is driving greater electricity demand and necessitating grid upgrades. The main grid sector is expected to benefit from the acceleration of UHV construction and the growing number of flexible DC projects [4] - The distribution network sector is also poised for growth due to ongoing domestic upgrades and strong overseas demand for transformers. Companies such as Huaming Equipment, Haixing Electric Power, and others are recommended for investment [4]
