On May 15, 2023, the Hubei Yingcheng 300-megawatt-class compressed air energy storage power station demonstration project invested by Energy China Digital Technology Group and constructed by the Central South Institute completed the important milestone node of zero meters of the main plant foundation, marking the The overall construction of the main part of the main factory building below zero meters has been completed, and will soon move to the civil construction and equipment installation parts above zero meters, laying a solid foundation for the completion of the overall goal of the project construction.

The project is located in Yingcheng City, Hubei Province, an energy storage base in central China. Utilizing the rich salt cavern resources in Yingcheng area, a 300 MW/1500 MWh compressed air generator set and supporting energy storage power generation production area, auxiliary production area and For the auxiliary infrastructure, the construction period of the first phase of the project is 18 months, and it is expected to be completed and put into production in June 2024.

The project adopts compressed air energy storage power generation technology, which can effectively reduce the project cost and land occupation, and has the characteristics of safety and environmental protection. At the same time, it is beneficial to improve the power quality and power balance of the power system, especially suitable for matching with new energy projects or absorbing excess power of new energy.

After the project is completed, it is estimated that the annual power generation will reach 500 million kWh. In the field of compressed air energy storage, it will achieve world-leading stand-alone power, energy storage scale, and conversion efficiency. A buildable solution is provided.

Principles of Power Plant Operation

Since the official start of construction on February 1, 2023, the general contracting project department of Yingcheng Compressed Air Energy Storage Power Station of Central South Institute has always adhered to the scientific, standardized, strict and orderly management concept, equipped with a professional and experienced project management team, actively Coordinate all participating parties to fully and efficiently promote the work of the project.

Up to now, the foundation of the main plant building and the zero-meter short column construction have been completed, the bottom plate of the turbine and compressor base has been poured, the pile foundation construction of the hot and cold water tanks has been completed, and the plugging of old wells 306 and 308 has been completed, and the upper part of the main plant building will start soon. structure construction.

The project aims to build a first-class power station and create a high-quality project, effectively integrates various resources, and adheres to careful design, careful planning, and fine management to ensure the safety, quality and progress of the project and other work objectives.

Next, all employees of the general contracting project department will continue to carry forward the tenacious and hard-working style and the spirit of unity and cooperation and dedication, strengthen confidence, face up to difficulties, and promote the safe and smooth construction of the Yingcheng project with high standards and high quality. The Yingcheng project has been built into a first-class benchmark project.Editor/ZhangHui
