Zelestra, Sungrow Ink Chilean BESS Deal

Wedoany.com Report-May 24, Zelestra has selected Sungrow to provide battery energy storage system (BESS) technology for one of the largest storage projects currently under development in Latin America. The project, located in Tarapacá, Chile, is part of the hybrid Aurora energy project and includes both solar generation and large-scale battery storage components.

Under the agreement, Sungrow will supply its PowerTitan 2.0 liquid-cooled battery energy storage system, along with medium-voltage power conversion units. The total storage capacity of the BESS system is approximately 1GWh. Sungrow is also providing its 1+X modular inverter for the 220MWdc solar plant component of the project.

The Aurora project will enable Zelestra to deliver solar energy to the Chilean energy company Abastible during nighttime hours through a long-term power purchase agreement. Construction at the site is already in progress. Once operational, the project is expected to produce about 600GWh of renewable electricity annually, enough to meet the yearly consumption of around 200,000 households in Chile.

Delivery of the BESS units is scheduled to begin in the fourth quarter of 2025.

Zelestra CEO Leo Moreno commented: “With this major agreement, we have secured some of the most advanced BESS technology available in the market to deliver one the largest battery storage projects ever in Latin America. This is an important milestone for the Aurora project, as we advance towards the delivery of this highly customised hybrid solution that will meet the needs of our customer, Abastible.”

Sungrow Vice-Chairman Jack Gu stated: “We are proud to partner with Zelestra on the landmark Aurora project, delivering our cutting-edge PowerTitan 2.0 energy storage solution as well as PV inverters to one of the most significant hybrid projects in Latin America. This collaboration reflects our shared commitment to accelerating the energy transition in Chile and across the region, while ensuring a reliable, sustainable power supply for Chilean homes. Together, we are unlocking the full potential of solar and storage to build a greener future.”

This project marks a significant step forward in expanding energy storage infrastructure in the region and supports long-term goals for renewable energy integration and grid reliability in Chile.
