Zelestra and Sungrow Team Up for 1 GWh Battery Megaproject in Chile

Aurora Hybrid Scheme Aims to Power 200,000 Homes with Solar-Storage Combo

Latin America’s renewable energy landscape just got a major jolt. Zelestra, the clean energy developer, inked a deal with Chinese tech giant Sungrow to deploy a 1 GWh battery energy storage system (BESS) in Chile’s Tarapacá region. The project, part of the Aurora hybrid scheme, pairs the massive storage array with a 220 MWdc solar plant—marking one of the region’s most ambitious decarbonization plays.

“This isn’t just about megawatts; it’s about rewriting Chile’s energy DNA,” said Zelestra’s CEO during the announcement. “Storage unlocks 24/7 renewables, and that’s the endgame.”

Sungrow’s hardware will anchor the effort. The PowerTitan 2.0, a liquid-cooled BESS with MV conversion units, will store enough electricity to pump ~600 GWh annually into Chile’s grid—enough for 200,000 households. Meanwhile, the solar side leans on Sungrow’s 1+X modular inverters, using an 8.8 MW block design to maximize efficiency. Construction crews are already on-site, with BESS deliveries slated for Q4 2025.

Zelestra’s Latin American Dominance

The deal underscores Zelestra’s growing clout. With a 7 GW project pipeline across Latin America—including 1.7 GW in active development—the company is a renewable heavyweight. BloombergNEF ranks it among the top 10 global clean energy sellers to corporations, and it holds the #2 spot in Europe, the Middle East, and Asia for such deals.

“Hybrid projects like Aurora prove renewables can be both scalable and reliable,” noted Sungrow’s VP. “The 1 GWh storage component isn’t incremental—it’s transformative.”

Chile’s energy matrix, long reliant on fossil fuels, is primed for disruption. The Aurora scheme’s dual solar-storage approach could become a blueprint for neighboring countries racing to meet COP28 targets. For Zelestra, it’s another step toward cementing Latin America as the next frontier for grid-scale innovation. And with construction timelines tightening, the clock is ticking.
