Sungrow secures energy storage deal for Chile with WEG-4 Fund

Sungrow, a global leader in inverters and energy storage systems, has inked a deal with the Investment Fund WEG-4 to provide a 60MW/132MWh liquid-cooled energy storage system (ESS), known as PowerTitan, for a project within Chile’s 72.8MW Maria Elena Solar Park in Antofagasta. This initiative will bolster the stability and adaptability of the Chilean National Electric System while supporting local carbon-neutral objectives.

Following several years of operation at the Maria Elena Solar Park, stakeholders have introduced energy storage to optimise energy utilisation. The energy storage system will capture solar energy during the day and release it to the grid during the night, significantly enhancing both the solar park’s efficiency 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.

Eduardo Escaffi, partner from WEG-4, Maria Elena Solar Park’s owner, stated, “WEG-4’s commitment to continue investing in assets that contribute to a better environment is evident in the Maria Elena Energy Storage project. We selected Sungrow as our dedicated ESS provider due to their proven track record in the energy storage market, and the competitive features of their products and services, securing the best performance of our assets in the long term.” WEG-4 is a public fund managed by WEG AGF, a prestigious Chilean asset manager established in 2015.

Ada Li, Vice President of Sungrow Americas, expressed, “Energy storage is essential for decarbonising the Chilean energy system. WEG-4 is at the forefront of enabling the energy transition of this country and we at Sungrow are happy to assist them in creating a better and cleaner future by cutting-edge offerings.”

Chile’s ambitious climate objectives target a 70% renewable energy share in its electricity generation by 2030. The integration of solar-plus-storage solutions is emerging as a sustainable, long-term strategy to enhance power grid reliability.
