Zelestra has finalized a significant agreement with Sungrow that paves the way for the enhancement of one of Latin America’s largest battery energy storage systems (BESS) as part of the Aurora hybrid project in Tarapacá, Chile. This partnership will see Sungrow supply its innovative PowerTitan 2.0 liquid-cooled BESS along with MV power conversion units, which are integral to the project.
The BESS system is designed to offer a storage capacity of around 1 gigawatt hour (GWh), providing vital support to the Aurora project’s 220-megawatt solar plant, which utilizes Sungrow’s 1+X Modular Inverter technology. This project highlights Zelestra’s ability to implement multi-technology solutions, ensuring a consistent supply of solar energy to Abastible, a Chilean firm, through a long-term power purchase agreement (PPA).
Zelestra’s CEO, Leo Moreno, emphasized the importance of this milestone, stating that the acquisition of advanced BESS technology positions them to deliver one of the largest storage initiatives in Latin America. The ongoing construction at the Aurora site is expected to produce approximately 600 GWh of renewable electricity annually, enough to supply energy to 200,000 Chilean households and significantly aid in the country’s decarbonisation efforts.
Moreover, deliveries of the BESS units are anticipated to commence in the fourth quarter of 2025. Sungrow’s vice-chairman, Jack Gu, expressed pride in collaborating on this project, reinforcing their commitment to facilitating the energy transition in Chile and ensuring sustainable power for the region’s homes.
In a related development, Zelestra has also achieved financial closure for six solar PV projects in Spain, including the Belinchón and Brazatortas clusters. This financial framework involves 21 PPAs and a €146.6 million senior debt package, underpinned by green financing for the construction phase, with key involvement from BNP Paribas and Rabobank as mandated lead arrangers.
This project not only represents a technical advance for Zelestra and Sungrow but also underscores the broader efforts in Latin America to transition towards renewable energy sources, contributing to a more sustainable future.
