Sineng Electric Enhances Grid Stability with Commissioning of 150MW/300MWh Energy Storage Project

Huaian, China, March 31, 2025 – Energy storage is transforming the electrical grid, serving as a vital enabler of renewable energy integration by mitigating the intermittency of solar and wind power. Committed to pioneering energy storage innovations, Sineng Electric has deployed its high-power central PCS in a 150MW/300MWh energy storage project in Huaian, China.

The project utilizes battery energy storage system (BESS) containers featuring six clusters connected to a single PCS. Unlike the conventional 12-cluster configuration, this design reduces the number of parallel clusters on the DC side by half, significantly lowering the risk of circulating current. With fewer parallel connections, energy losses are minimized, resulting in a 3% increase in system utilization, thereby optimizing the LCOE. Sineng's 5MW MV turnkey station, configurable with four units of 1250kW central PCS, seamlessly integrates with these BESS containers, ensuring optimal performance, enhanced safety, and improved economic efficiency.

As a standalone energy storage installation, the project plays a crucial role in renewable energy self-consumption optimization, frequency regulation, and peak shaving, supporting the region's transition toward a low-carbon, sustainable energy future. Now fully operational, the energy storage power plant is expected to achieve an average daily discharge of 480,000 kWh, offsetting 160 tons of coal consumption and reducing carbon dioxide emissions by approximately 425 tons.

With this deployment, Sineng Electric reaffirms its leadership in energy storage innovation, continuously delivering high-performance solutions that optimize global energy infrastructure and contribute to a cleaner, more resilient power grid.
