BYD Opens America's Largest Battery Storage in Chile

Deep in Chile's Atacama Desert, a groundbreaking energy project just went live that could change how an entire continent stores and uses renewable power.

BYD, a Chinese clean energy company, supplied the batteries for the Elena project, now the largest battery storage facility in the Americas. The system can store 3.5 gigawatt-hours of energy, enough to power hundreds of thousands of homes during peak demand.

Spanish renewable energy company Grenergy developed the massive facility using 6,240 battery modules from BYD, all housed in 624 containers. The scale is impressive, but the timing matters even more.

As solar and wind farms spread across the globe, they face one stubborn challenge: the sun doesn't always shine and the wind doesn't always blow. Battery storage solves this problem by capturing excess electricity when production is high and releasing it exactly when people need it most.

Chile is quickly becoming a clean energy powerhouse. The country's Atacama Desert offers some of the best solar conditions on Earth, and battery storage helps ensure none of that sunshine goes to waste.

BYD isn't stopping with Elena. The company already has contracts for more than 9 gigawatt-hours of battery storage capacity across Chile, including another project expected to come online between 2026 and 2027.

Meanwhile, BYD is expanding aggressively in Europe, where it sold nearly 188,000 electric vehicles in 2025 alone, a 270% jump from the previous year. The company plans to open its first European car factory in Hungary during the fourth quarter of 2026.

The Ripple Effect

The Elena project represents something bigger than one impressive battery system. It shows how energy storage is becoming essential infrastructure for the clean energy transition.

According to the International Energy Agency, over 20% of all new cars sold worldwide in 2024 were electric. As EV adoption grows and renewable energy becomes cheaper, battery storage creates the missing link that makes it all work together.

Grid operators worldwide are investing heavily in battery systems to support growing amounts of solar and wind power. What's happening in Chile's desert today could become standard practice everywhere tomorrow.

For communities across the Americas, projects like Elena mean more reliable renewable energy, lower electricity costs, and cleaner air. The batteries don't just store energy. They store possibility.
