1GW/4GWh！内蒙古阿荣旗构网型储能项目正式投运

Core Viewpoint - The article highlights the successful launch of the 1 million kW/4 million kWh grid-type energy storage project in Arongqi, Hohhot City, Inner Mongolia, which is expected to enhance renewable energy consumption and improve grid stability [1][4][6]. Group 1: Project Overview - The energy storage project officially commenced operations on December 6, with a total investment of 2.5 billion yuan [1]. - The project utilizes grid-type energy storage technology and lithium iron phosphate batteries, featuring a single storage unit capacity of 1.25 MW/5 MWh and a cycle life exceeding 6,000 times [1][6]. - A total of 800 battery units have been constructed to meet the energy storage demands [1]. Group 2: Technical Features - The project includes the implementation of black start technology, which provides the grid with self-healing capabilities, allowing it to restore operations after a complete failure [6]. - The system can instantaneously supply short-circuit current during grid faults, addressing challenges related to high proportions of renewable energy integration [6]. Group 3: Economic and Environmental Impact - The project is expected to increase the consumption rate of surrounding wind and solar energy by 6%, allowing for an additional 1.2 billion kWh of clean energy to be utilized annually [6]. - It aims to reduce the curtailment rates of renewable energy by approximately 6% and output green electricity of 1.032 billion kWh each year, leading to a reduction in coal consumption by about 300 million tons [6]. - The project will enhance the grid voltage qualification rate to over 99.9% and achieve a power supply reliability rate of 99.99%, supporting the low-carbon transition of the energy structure in the eastern Inner Mongolia region [6].
