As it moves into the electrical commissioning phase, China’s largest electrochemical energy storage project, 600MW/2400MWh, has reached a significant milestone with the installation of all storage cabins at its initial location. This is the first ultra-high voltage (UHV) transmission project in China that combines solar, wind, thermal, and storage. The utility-scale 1725kW Power Conversion System (PCS) from SINEXCEL (300693.SZ) is honored to power this national-level project.
There are 60 PCS skids and 240 battery containers at this location. When the project is complete, it will add around 840 GWh of renewable energy per year to the grid. Up to 2.4 GWh can be stored on a single charge, which is sufficient to power 36,000 EVs with a 500 km range or 480,000 families’ daily electricity demands.
Furthermore, SINEXCEL provided help for a 220MW/880MWh storage facility in Ningxia that was successfully grid-connected. Utilizing the region’s plentiful solar resources, the project combines solar and storage to improve grid stability, address renewable energy curtailment, and facilitate energy shifting. It is anticipated that the station would provide close to 200 GWh of power per year.
SINEXCEL uses its 1725kW PCS to support these two projects. The 1725kW PCS has a modular architecture that can scale from 215kW to 1.72MW per unit and is intended to improve grid stability. It supports a variety of battery types, combines the benefits of both string and centralized arrangements, and allows for flexible deployment across a range of storage situations, including as front-of-the-meter applications, microgrids, and massive C&I.
The PCS offers versatile configurations with 1, 2, 4, or 8 battery strings and boasts cutting-edge multi-string technology for improved battery safety, with a peak efficiency of up to 98.5%. Its NEMA 3R-rated cabinets guarantee outdoor durability, and its dual AC/DC output makes control and extension easier. The device satisfies significant compliance regulations in North America, Europe, Australia, Japan, and China, and its quick 10 ms reaction time facilitates real-time grid balancing.
Offering solutions for utility-scale, C&I, and microgrid applications, SINEXCEL has deployed more than 12GW of storage capacity in more than 40 countries and more than 5,000 deployments globally.
Participating successfully in these historic initiatives demonstrates SINEXCEL’s technical prowess and unwavering dedication to facilitating a more sustainable and resilient energy future.
