Sungrow Power Supply Co., Ltd. signed a contract with the Investment Fund WEG-4 to supply 60MW/132MWh of its liquid cooled energy storage system (ESS) solution, the PowerTitan to Chile. This project, located within the 72.8MW Maria Elena Solar Park in Antofagasta, Chile, will enhance the stability and flexibility of the Chilean National Electric System, supporting local carbon-neutral ambitions. The Maria Elena Solar Park was commissioned in 2015.

After a few years of the solar park's operation, the stakeholders introduced energy storage for energy shifting. The energy storage system will store the renewable energy from the solar plant during the day and release it to the grid at night, increasing the overall efficiency of the solar park and grid stability. Sungrow's liquid cooled ESS PowerTitan will be used for this installation.

The solution is designed based on Sungrow's power electronics, electrochemistry, and power grid support technologies. It cuts capital and operating expenses due to its pre-assembled and easy installation design, and with a more effective cell working environment which substantially decreases the capacity loss rate. Its DC-DC controller can charge and discharge battery racks individually; thus, increasing the overall system performance.

These features earned PowerTitan as the world's first iF Design Award winner in the utility-scale energy storage system category.
