Group 1 - The company, Three Gorges Energy (600905), clarified on an interactive platform that its Shandong Qingyun Phase II 201MW/402MWh energy storage project did not utilize battery packs and battery management systems from CATL (300750) [1] - The Jiangsu Dongtai Gong Port 30MW/60MWh sodium-ion energy storage station is not part of the company's investment and construction projects [1]

Core Viewpoint - The expansion of the sodium-ion battery energy storage station in Wuming District, Nanning, Guangxi, has officially commenced operations, increasing its capacity from 10 MWh to 50 MWh, thereby enhancing its role in renewable energy consumption and grid regulation [1][3]. Group 1: Project Expansion - The second phase of the energy storage station has been completed, increasing the total capacity to 50 MWh, which can store 50,000 kWh of green electricity [1][3]. - The upgraded system utilizes newly developed 240 Ah sodium-ion batteries, which represent a 14% increase in capacity compared to the first phase [3]. Group 2: Operational Impact - Since its launch in May 2024, the first phase has stored and released over 1.3 million kWh of green electricity, playing a significant role in grid regulation and renewable energy consumption [3]. - The expanded station can charge and discharge up to 600 times annually, contributing an additional 30 million kWh of renewable energy consumption, equivalent to reducing coal consumption by 9,000 tons and cutting CO2 emissions by 13,500 tons [3]. Group 3: Technological Significance - Sodium-ion batteries are emerging as a crucial supplement in the energy storage technology matrix due to their unique advantages, supporting the broader adoption of renewable energy [3].
