en.Wedoany.com Reported - The Inner Mongolia Tongwei Green Base New Energy Storage Project, invested and constructed by Baotou No.1 Power Plant of Huaneng North Company, has achieved full-capacity grid-connected power generation. This project is the nation's first "grass-solar complementarity" pilot project in desert steppe areas, as well as one of the first batch of industrial park direct green power connection projects nationwide and the first wind-solar-storage co-located project in the Inner Mongolia Autonomous Region.

The total planned capacity of the project is 350,000 kilowatts, comprising 300,000 kilowatts of wind power and 50,000 kilowatts of photovoltaic power generation, along with a supporting 90 MW/360 MWh electrochemical energy storage device. The green electricity ratio for the industrial silicon industry on the consumption side reaches 50.17%. The energy storage system adopts the decentralized control battery energy storage technology independently developed by Huaneng Clean Energy Research Institute (Huaneng Clean Energy Institute). Through cluster-level refined energy management, it resolves issues such as the "barrel effect" and inter-cluster circulating currents found in traditional centralized energy storage, thereby enhancing the system's available capacity, operational safety, and cycle life.

The project is located in a desert steppe area with relatively complex construction conditions. The construction team ensured the project's on-schedule grid connection through scientific construction organization and strict quality control. The successful commissioning of this project holds demonstrative significance for promoting the application of direct green power supply models, advancing the integrated development of wind-solar-storage, and achieving synergistic benefits between ecological protection and energy development. It will provide replicable practical experience for the large-scale development of new energy in China's desert steppe regions.
