This project is located in Panzhou, Liupanshui City, Guizhou Province. The Hopewind energy storage system, with hopeEMS as its integrated control platform and two 2.5MW centralized PCS units, serves as an "emergency power source" for the coal mine. It establishes a "safety barrier" for the coal mine's power supply while also reducing electricity costs through peak-valley arbitrage. This project has become a benchmark case for energy storage applications in coal mines.
