China’s Largest Electrochemical Energy Storage Project

On June 11, 2025, China celebrated the completion of the installation of all storage containers at the largest electrochemical energy storage project in the nation. With an impressive capacity of 600 MW/2,400 MWh, this groundbreaking initiative is set to revolutionize the way renewable energy is harnessed and utilized.

Equipped with a powerful 1,725 kW Power Conversion System (PCS) developed by SINEXCEL, this facility is considered a pivotal milestone as it transitions into the operational phase. Moreover, the project stands out as China’s first ultra-high voltage (UHV) transmission project that integrates wind, solar, thermal energy, and storage, providing a comprehensive solution to the energy challenges of the future.

The facility comprises 240 battery containers and 60 PCS units. Once operational, it is projected to contribute approximately 840 GWh of renewable energy to the grid annually. To put this in perspective, this amount of energy storage is sufficient to meet the daily electricity needs of about 480,000 households or power 36,000 electric cars with a range of 500 km per charge.

Enhancing Energy Security with SINEXCEL

In addition to this massive scale project, SINEXCEL has also successfully supported another energy storage initiative with a capacity of 220 MW/880 MWh, linked to the Ningxia grid. This project takes advantage of the region’s abundant solar resources and seamlessly integrates solar energy with storage technologies. This strategic approach aims to mitigate the inherent limitations of renewable energy sources, boost grid stability, and facilitate the transition among various energy sources. The Ningxia facility is expected to supply nearly 200 GWh of electrical power each year.

SINEXCEL's contribution to these projects hinges on their state-of-the-art PCS, which is tailored to enhance grid stability. This modular system, designed for scalability, allows capacities ranging from 215 kW up to 1,725 kW per unit, integrating the benefits of both centralized and chain configurations. It supports various battery technologies, making it adaptable for various storage scenarios, from large commercial and industrial applications to microgrids and pre-metering applications.

Boasting a maximum efficiency of 98.5%, the PCS is equipped with advanced multi-core technology aimed at ensuring battery protection while also supporting flexible configurations of 1, 2, 4, or 8 battery strings. Its combined AC/DC output simplifies management and expansion, while NEMA 3R rated enclosures ensure resilience against challenging environmental conditions. The quick 10 ms response time facilitates real-time grid balancing, meeting critical standards across North America, Europe, Australia, Japan, and China.

This global endeavor by SINEXCEL, operational in over 40 countries with more than 5,000 installations worldwide, speaks volumes to their commitment to drive innovation in energy storage solutions. Having already installed over 12 GW of storage capacity and partnered with industry stalwarts like EVE Energy and Schneider Electric, SINEXCEL exemplifies a dedication to empowering energy independence and sustainability.

The successful execution of these groundbreaking projects underscores SINEXCEL's technical prowess and its unwavering commitment to facilitating a more resilient and sustainable energy future.
