The Alashan grid-side energy storage power station project, undertaken by MCC CERI, is a major breakthrough in the field of energy storage engineering in Alashan League. It is planned to build 100,000 kW of energy storage capacity and 400,000 kWh of energy storage capacity. The project was completed in just 88 days, achieving full-capacity grid connection and dynamic debugging, and successfully passed testing for commercial use. After the project is put into operation, it will play a full role in peak shaving and valley filling, alleviate the contradiction between power supply and demand, and play an important role in optimizing the regional energy structure and accelerating the implementation of the "dual carbon" target.
