Chile is writing an inspiring success story in renewable energy, with the country's clean energy association Acera celebrating remarkable achievements that signal a bright, sustainable future for the nation.

In what can only be described as a breakthrough year, Chile's battery energy storage capacity has tripled, jumping from 3 gigawatts to an impressive 9 gigawatts by the end of 2025. This tremendous growth demonstrates the country's unwavering commitment to clean energy and positions Chile at the forefront of Latin America's green energy revolution.

"Energy storage is redefining system operations, enabling greater renewable energy integration and strengthening flexibility and operational security," shared Ana Lía Rojas, executive director of Acera, the Chilean renewables and energy storage association. Her words reflect the optimism permeating the sector as innovative technologies transform how the country generates and uses electricity.

The growth extends far beyond what's already operational. An additional 27 gigawatts of storage projects are currently moving through various evaluation phases, signaling that Chile's clean energy expansion is just getting started. This pipeline of projects represents extraordinary confidence in the country's renewable future and its ability to lead the energy transition.

Investment is flowing robustly into Chile's energy sector, with generation and storage projects attracting $4.49 billion in 2025, nearly double the $2.50 billion invested the previous year. This surge in capital reflects global recognition of Chile's favorable conditions for renewable energy and its commitment to creating a stable, supportive regulatory environment.

The country's installed grid capacity has grown to 38.6 gigawatts, with renewable energy sources now representing nearly half of all capacity. Clean energy projects account for an impressive 49.8 percent of the total, showcasing how quickly Chile is transitioning away from fossil fuels toward a sustainable energy future.

Looking ahead, projections suggest Chile's installed capacity will reach 47.2 gigawatts by December 2027, with an astounding 95 percent of new projects entering the system being renewable energy and storage initiatives. This trajectory places Chile firmly on track to become one of the world's cleanest energy systems.

The sector is also celebrating innovation, with pioneering storage projects featuring grid-forming technology currently under construction. These cutting-edge systems will provide synthetic inertia, further enhancing grid stability and enabling even greater renewable energy integration.

Chile is now entering what experts call a "third phase" of wind development, with new projects totaling around $2 billion recently entering the environmental review process. These developments are strategically located to maximize output and efficiency, demonstrating the sector's increasing sophistication.

The progress hasn't gone unnoticed internationally. Chile's success in rapidly scaling renewable energy while maintaining grid reliability serves as an inspiring model for other nations pursuing their own clean energy transitions.

While challenges remain, including the need for continued regulatory refinement and transmission infrastructure expansion, the momentum is undeniably positive. The upcoming completion of major transmission projects like the $1.5 billion Kimal–Lo Aguirre line will further enhance the system's ability to deliver clean energy across the country.

Chile's renewable energy transformation represents more than just environmental progress—it's creating jobs, attracting investment, and building a foundation for sustainable economic growth that will benefit generations to come.
