Latin America Energy Storage to Grow 13x by 2035

Latin America is experiencing an energy storage revolution that could power millions of homes with reliable, clean electricity.

Energy consultancy Wood Mackenzie just released projections showing the region's battery storage capacity will multiply nearly 14 times between now and 2035. That growth from 2.5 gigawatts to 34 gigawatts represents enough storage to stabilize grids powered by wind and solar across an entire continent.

The forecast itself is a sign of accelerating progress. Just six months ago, the same consultancy predicted the region would reach only 23 gigawatts by 2034.

Chile leads the charge today with the largest battery energy storage systems currently operating in Latin America. The country's high renewable energy production created a perfect testing ground for long-duration storage systems that can hold power for hours.

Mexico stands at a turning point. New strategic project mechanisms could deliver more than 3 gigawatts of storage capacity through 2030. The country has identified seven regions needing standalone battery systems, each capable of storing power for three hours. A new policy also requires renewable energy projects to include storage equal to 30% of their capacity.

Brazil is preparing two groundbreaking auctions in December 2026 specifically for large-scale battery systems. One auction will prioritize domestically manufactured systems, while the other stays open to all technologies. Winners will sign 15-year contracts to supply storage starting in August 2028.

Argentina built a functional storage market in just over a year. Recent auctions have already awarded 1.3 gigawatts of battery capacity to ease grid bottlenecks while transmission upgrades happen.

The Dominican Republic now requires renewable projects over 20 megawatts to include storage equal to half their capacity. The batteries must hold power for at least four hours.

The Ripple Effect

This storage boom solves a critical challenge facing renewable energy. Solar and wind power generate electricity when nature provides, not always when people need it. Battery systems bridge that gap, storing excess clean energy for evening peaks or cloudy days.

The expansion means fewer emissions from backup fossil fuel plants. It means more stable electricity grids in regions where blackouts have hindered development. It means renewable energy projects become more financially viable, encouraging even more clean power construction.

Countries establishing clear payment structures and regulations will convert their project pipelines into working systems fastest. The race is on to build frameworks that attract investment while delivering reliable grid services.

Latin America is proving that emerging markets can leapfrog directly to advanced clean energy infrastructure. The storage revolution happening now will enable the next generation of renewable power across the region.
