云南能投安宁350MW盐穴压缩空气储能示范项目开工

Core Viewpoint - The Yunnan Energy Investment Group has officially commenced the construction of the 350MW salt cavern compressed air energy storage demonstration project in Anning City, which aims to support the national "dual carbon" goals and enhance the stability of the power grid in high-altitude regions [1][2]. Group 1: Project Overview - The total investment for the project is 1.872 billion yuan, making it a key initiative for Yunnan Province to develop a new power system [1]. - The project will utilize retired salt caverns (An1-An4) as energy storage mediums, with a designed operating pressure of 7MPa-9MPa and a construction scale of 350MW/1750MWh [1]. - The energy storage system is designed to operate on a "low valley storage, high peak release" principle, allowing for flexible energy regulation [1]. Group 2: Technical Specifications - The project will have an annual utilization of at least 1,300 hours, with an expected annual power generation of 465 million kilowatt-hours [1]. - The system can store up to 1.75 million kilowatt-hours of electricity, with a storage duration of 8 hours and an average turnover of 260 cycles per year [1]. - The construction includes an air compression system, turbine power generation system, heat exchange system, and a 220kV booster station, integrating into the Yunnan power grid [2]. Group 3: Strategic Importance - The project is a critical component of Yunnan Energy Investment Group's "8+X" energy industry system, promoting the integration of green electricity and energy storage [2]. - It addresses the technical challenges of high-altitude environments by collaborating with universities and research institutions to develop a specialized energy storage system [2]. - The implementation of this project is expected to stabilize fluctuations in renewable energy generation and enhance the grid's capacity to accept large-scale green electricity [2]. Group 4: Local Government Support - The Anning City government has committed to optimizing the business environment and providing excellent service to support the project's construction [3].
