Zelestra Energises 1GWh Hybrid BESS Project in Chile

Why It Matters

The Aurora project demonstrates strong investor confidence in hybrid storage as a cornerstone for Chile’s renewable‑grid integration, accelerating the country’s path toward a resilient, low‑carbon power system.

Key Takeaways

• Zelestra secured $282 M financing for 1 GWh hybrid BESS in Chile
• Project uses PowerTitan 2.0 5 MWh battery and 2.5 MW PCS container
• EPC handled in‑house, commissioning expected within weeks
• Chile’s BESS pipeline now exceeds 1 GW of capacity
• Hybrid storage boosts grid reliability for mining and renewable sectors

Pulse Analysis

Chile has become a global hotspot for utility‑scale battery‑energy‑storage systems, driven by abundant solar resources and a mining sector that demands firm, dispatchable power. Zelestra’s Aurora project, a 1 GWh hybrid BESS, exemplifies this trend by pairing a compact PowerTitan 2.0 battery with a 2.5 MW power conversion system, all within a containerized footprint. The $282 million financing package, led by Natixis CIB and BNP Paribas, underscores the growing appetite among European banks for Latin American clean‑energy assets, while the VAT facility from BCI reduces the project's fiscal burden.

The Aurora development arrives amid a flurry of high‑profile projects in the Atacama region, including Copenhagen Infrastructure Partners’ 300 MW/1,500 MWh Patache BESS, Sonnedix’s 117 MW/643.8 MWh Librillo installation, and Innergex’s 42 MW/210 MWh San Andrés II system. Zelestra’s decision to keep engineering, procurement and construction in‑house reflects a broader industry shift toward tighter project control and cost efficiencies. By delivering a hybrid solution that can both store energy and provide ancillary services, the project enhances grid stability for mining operations and renewable farms alike, positioning Chile as a testbed for next‑generation storage architectures.

Looking ahead, the momentum is set to continue as regional Energy Storage Summits spotlight financing models, policy frameworks, and hybridisation strategies. Germany’s upcoming summit aims to integrate 24 GW of storage by 2037, while the Latin America edition in Santiago will dissect Chile’s regulatory advances and supply‑chain developments. For investors and developers, Zelestra’s Aurora serves as a benchmark for how robust financing, modular technology, and local EPC expertise can accelerate the deployment of large‑scale hybrid BESS, ultimately supporting Chile’s ambition to decarbonise its power grid and export storage expertise globally.
