Chile Debuts the Largest Battery Storage Plant on the Continent

Spanish company Grenergy officially inaugurated Elena, the largest battery storage plant in the Americas, located in the commune of María Elena, in the Antofagasta Region, Chile.

With 3.5 GWh of capacity already commissioned, this megaproject represents the company’s most ambitious milestone to date and marks the start of the largest clean generation hub in northern Chile.

The infrastructure, which is part of the Oasis de Atacama hybrid platform, not only consolidates Chile’s leadership in renewable energy and large-scale storage but also lays the groundwork for attracting advanced digital infrastructure, positioning the country as an artificial intelligence and data center hub for Latin America.

During the inauguration, Grenergy also presented GR Data, its new digital infrastructure platform, with a 1 GW IT pipeline and projects that could attract up to US$25 billion in direct digital investment to Chile over the next three years.

Elena: The Largest Battery Plant on the Continent

Elena, with 3.5 GWh of storage already in operation, stands as the largest battery plant in all of the Americas. According to the company’s roadmap through 2028, its capacity is expected to expand to 7 GWh, doubling its current size.

The project—the most ambitious Grenergy has developed since its inception—is currently composed of 624 containers and 6,240 batteries. Its construction mobilized over 400 workers, generating a significant boost to the local economy and strengthening ties with the community through educational and social initiatives in María Elena.

This cutting-edge infrastructure makes it possible to deliver renewable energy continuously, 24 hours a day, seven days a week, helping to accelerate industrial electrification, the decarbonization of mining, and the advancement of electromobility.

Elena is part of the Oasis de Atacama platform, a pioneering model for integrating solar generation and energy storage that, according to the roadmap recently announced by the company, includes 2.5 GW of solar capacity and 14.1 GWh of storage.

This platform is the origin of the hybridization model that Grenergy is replicating in central Chile through Oasis Central (1.4 GW solar, 5.1 GWh storage) and exporting to Spain through Iberian Oasis (1 GW solar, 3.2 GWh storage).

Together, the OASIS platforms total 5 GW of solar capacity and 22 GWh of storage, consolidating Chile as a global benchmark in the transition toward cleaner, safer, and more competitive electrical systems.

24/7 Dispatchable Energy for Industry and Mining

From Elena, Grenergy is driving the largest energy hub in northern Chile—a development that integrates 2.1 GW of solar capacity and 14 GWh of storage. The hub delivers dispatchable energy 24 hours a day, reinforces supply security, and provides the flexibility the grid needs to integrate more renewables and cope with demand peaks and extreme weather events.

This infrastructure is key to accelerating industrial electrification, the decarbonization of mining—one of Chile’s most relevant productive sectors—and the advancement of electromobility, reducing dependence on volatile fuels and ensuring cleaner, more stable, and competitive energy.

Furthermore, Grenergy, backed by its ability to generate clean and competitive energy, presented new details of GR Data, its digital infrastructure platform for data centers in Chile.

The platform, with a 1 GW IT pipeline, could attract up to US$25 billion in direct digital investment to the country over the next three years, accounting for the participation of other involved players:

• The first GR Data development will be Atacama Data, a campus specialized in artificial intelligence training located near Elena, which will start with 400 MW IT and be scalable to 1 GW IT, operating on renewable energy with no water consumption for its operations.
• They will be joined by the cloud campuses Polpaico Campus Norte and Alto Jahuel Campus Sur, located near Santiago, which together will contribute an additional 600 MW IT alongside the country’s main connectivity nodes.

With strategic locations, secured connections, and competitive energy, Grenergy is consolidating itself as a key partner for hyperscalers and as a driver of next-generation digital infrastructure in Chile.

Grenergy has invested US$2.8 billion in the country, its main market, and plans to add another US$2 billion over the next two years, reaching an accumulated investment of US$4.8 billion.

A Year 2026 of Consolidation for Mobility

The Latam Mobility 2026 Tour will arrive in Santiago, Chile, on August 25, bringing together experts and strategic players to further strengthen the sustainable mobility ecosystem in the region.

The tour will end in Mexico City on October 12 and 13, alongside the Climate Economy Forum, in a meeting that will bring together sector leaders to continue driving the transition toward more efficient, sustainable, low‑emission transportation systems in Latin America.

The transition is already underway. The Latam Mobility 2026 Tour will be the meeting point to accelerate decisions, connect key players, and collaboratively build sustainable mobility in Latin America.
