Benefits of energy storage + mining
It should be noted that the "energy storage + mining" model not only helps solve the energy consumption problem of mining companies, but also brings many other benefits.
Reduce operating costs: By utilizing energy storage technology, mining companies can optimize energy use and reduce operating costs. The energy storage system can provide additional power support during peak periods of electricity demand, thereby reducing the company's electricity costs. At the same time, the energy storage system can also reduce dependence on traditional power supply systems and reduce maintenance costs.
Improve production safety: The existence of the energy storage system can ensure the stability of power supply, thereby improving the production safety of mining companies. In the event of a power outage, the energy storage system can start quickly to provide power support for key equipment and ensure the continuity and safety of the production process.
Promote the development of green mining: By using energy storage technology, mining companies can optimize the energy structure, reduce the impact on the environment, and promote the development of green mining. This helps mining companies cope with the challenges of increasingly stringent environmental protection requirements and achieve sustainable development.
Promote technological innovation and industrial upgrading: The application of energy storage technology will promote mining companies to take greater steps in technological innovation and industrial upgrading. By introducing advanced energy storage technology and equipment, mining companies can improve production efficiency, improve product quality, and enhance market competitiveness.
According to preliminary statistics from WIN ENERGY, since 2021, in addition to shared energy storage in large power stations, about 20 mining areas have adopted energy storage lithium batteries as backup power systems, with a total capacity of approximately 85MWh. These mining sites use an average of 1 to 2 containerized energy storage systems, with the capacity of each system ranging between 2 and 3MWh. This data shows that the application of energy storage lithium batteries in the field of power backup in mining areas has made significant progress.
Excellent cases of energy storage + mining
At the beginning of 2023, the "Fankou Lead-Zinc Mine 3MW/6MWh Energy Storage Project", a key technical transformation project of Zhongjin Lingnan Fankou Lead-Zinc Mine, successfully completed system commissioning and was successfully connected to the power grid. This marks the first in northern Guangdong. The user-side smart string energy storage project was successfully put into operation.
This project is also a typical user-side energy storage application scenario in mining areas. Fankou Lead-Zinc Mine provides the site to build one 1MW/2MWh and one 2MW/4MWh energy storage system, with a total installed capacity of 3MW/6MWh, container-type energy storage configuration, and 6kV grid-connected voltage level.
The products used in this project have 5-level simulation verification, 4-level early warning mechanism, 4-level fuse protection and 4-level linkage fire protection measures to ensure the safety of the energy storage system in an all-round way. At the same time, cloud platform big data analysis, remote maintenance intelligent diagnosis, AI investment income analysis and optimized operation strategies are used to achieve system intelligence and efficiency. After the project is successfully implemented, it can significantly save mining electricity bills and achieve an arbitrage model of low storage and high generation.
On September 25, 2024, Zhejiang Communications Investment Zhedong Mining Co., Ltd. started construction of its Toushan Mine Energy Storage Project in Sanmen County, Taizhou City, Zhejiang Province. It is reported that this is the first 10KV high-voltage user-side energy storage project in Sanmen County and is planned to be put into use in December.
The total installed capacity of the project is 4MW/8.2MWh energy storage system, container-type energy storage configuration, using the "two charging and two discharging" operation mode, and 10KV grid-connected voltage level. This project is a typical user-side energy storage application scenario in mining areas. After the project is completed, it is expected to save nearly 3 million yuan in electricity bills every year.
The energy storage system of this project is equipped with a comprehensive battery protection strategy and fault isolation measures, as well as an intelligent temperature and humidity adjustment system. It is also equipped with advanced safety and monitoring systems, including temperature, smoke, combustible gas detection devices, and automatic fire extinguishing systems, to achieve comprehensive fire warning, protection and linkage of the energy storage system, ensuring the safety, reliability and safety of the energy storage equipment system. Run smart and efficiently.
