Project Overview

In Luoyang, China, on July 25th, 2025, an energy storage system was implemented for the application of peak shaving.  The system is configured with a 10MWh lithium battery and a 5MW Power Conversion System (PCS).  It comes in a standard 20FT container size, which is designed to be conveniently integrated into the local energy infrastructure.

SolarEast Battery Energy Storage System’s 10MWh Liquid Cooling Battery Energy Storage System (BESS) has been successfully installed in Luoyang, China as part of a high-voltage solar hybrid system. This project showcases an innovative energy storage solution for industrial and commercial applications, providing a reliable and sustainable energy option for the region.

This case study will explore the advantages of liquid cooling technology, the system configuration, and its application in the China market. It will highlight how energy storage systems can enhance energy efficiency, reduce costs, and promote sustainable development.

The primary purpose of this system is peak shaving, which plays a crucial role in optimizing the power grid's performance.  By storing energy during off-peak hours and releasing it during peak demand periods, it helps to balance the power load and reduce stress on the grid.  The energy source for this system is the 3-phase AC local grid network, ensuring a reliable and stable power supply for the operation of the energy storage system.  This initiative not only contributes to the efficient use of energy in Luoyang but also showcases the city's efforts in adopting advanced energy management technologies to meet the growing energy demands in a sustainable manner.

The Role of Liquid Cooling Technology in Energy Storage

Liquid cooling technology is one of the standout features of this energy storage system. Compared to traditional air cooling systems, liquid cooling offers better efficiency in managing the temperature of battery modules, ensuring optimal performance and stability over extended periods.

By using liquid cooling, the 5MWh BESS maintains its efficiency in both high and low-temperature environments. This helps prevent overheating and thermal stress on the battery cells, which can otherwise degrade performance and reduce system lifespan. The liquid cooling system ensures the storage system runs efficiently, minimizing energy loss and prolonging the system’s operational life, thus reducing maintenance and downtime.

Why Energy Storage is Critical for Industrial and Commercial Applications

China’s industrial sector is experiencing growing energy demands, and businesses need reliable and cost-effective energy solutions. SolarEast ENERGY’s liquid cooling BESS is a perfect fit for these needs. The system allows companies to store excess energy generated by solar power during the day and use it during peak hours or at night when solar generation is low. This reduces reliance on the grid, cuts electricity costs, and increases energy independence.
