Latin America is entering a new stage of energy storage development as solar and wind power expand across the region. According to Wood Mackenzie's 2026 outlook, cumulative energy storage capacity is expected to increase from 2.5 GW in 2025 to 34 GW by 2035, representing more than 13 times growth over the decade.
The expansion of Latin America solar is one of the important factors supporting this trend. As renewable generation increases, countries need greater flexibility to manage electricity production, grid constraints and changing demand. This is creating new opportunities for BESS (battery energy storage system) projects.
However, Latin America does not have one single storage market model. Chile, Mexico, Brazil, Argentina and the Dominican Republic are developing energy storage through different policy and grid mechanisms.
Why Is the Latin America BESS Market Growing?
Solar power can produce significant electricity during periods of strong sunlight, while demand and grid conditions can vary throughout the day. Energy storage can help bridge this timing gap.
A solar battery can store electricity generated by solar PV and release it later. At larger scales, a grid battery can provide additional flexibility for renewable integration and grid operations.
Depending on project design, BESS can support:
♣Renewable energy integration
♣Energy shifting
♣Peak demand management
♣Grid flexibility
♣Solar curtailment management
♣Backup and resilience applications
This is also creating opportunities for both utility-scale projects and distributed storage, including home battery and commercial battery systems.
Chile: Renewable Curtailment Drives BESS
Chile remains one of the most advanced energy storage markets in Latin America.
The country's strong solar resources, particularly in northern regions, have contributed to renewable electricity curtailment and transmission constraints. This creates a strong use case for longer-duration BESS.
Storage can absorb excess solar generation and discharge electricity when renewable production falls or grid demand increases.
Chile therefore represents a curtailment-driven BESS market, closely connected to the country's expanding renewable generation.
At the same time, Wood Mackenzie identifies price cannibalization as a potential challenge as battery capacity increases in northern Chile. This demonstrates that the growth of BESS also changes electricity market dynamics.
Mexico: Policy Drives Energy Storage Development
Mexico is developing a different pathway for its energy storage market.
Government energy policy and strategic projects are expected to play an important role in BESS deployment. Wood Mackenzie estimates that new mechanisms and joint development schemes involving Comisión Federal de Electricidad (CFE) could result in more than 3 GW of storage capacity being awarded through 2030.
Mexico has also identified an indicative 935 MW of standalone energy storage projects, designed around three-hour durations, across several regions.
This makes Mexico a strong example of a policy-driven BESS market, where government planning and project mechanisms can influence the pace and structure of battery deployment.
Brazil: Capacity Auctions Create a New BESS Model
Brazil is preparing for a significant expansion of large-scale battery storage through dedicated capacity reserve auctions.
Two battery-focused auctions are scheduled for December 2026. Projects are expected to begin supplying capacity from August 2028, with contracts lasting 15 years.
The projects must have at least 30 MW of power capacity and four hours of storage duration.
This creates an auction-driven BESS market model.
For the wider solar market, dedicated storage auctions can provide a clearer pathway for integrating battery systems with large renewable energy projects.
Argentina: Grid Constraints Shape BESS Deployment
Argentina has rapidly developed a standalone energy storage market through auction activity.
Recent awards total around 1.3 GW, with projects primarily designed to address constraints at critical grid nodes and provide power and reserve services while transmission infrastructure is upgraded.
This makes Argentina a grid-constraint-driven BESS market.
Rather than focusing only on storing renewable electricity, battery systems can act as flexible grid infrastructure, helping address specific network limitations while longer-term transmission upgrades are implemented.
Dominican Republic: Storage Requirements Support Deployment
The Dominican Republic represents another distinctive model.
According to Wood Mackenzie's analysis, regulations require new renewable energy projects of at least 20 MWac to include storage equivalent to at least 50% of installed capacity, with a minimum duration of four hours.
The country is also targeting approximately 500 MW of storage by 2030.
The Dominican Republic therefore demonstrates a storage-mandate-driven market model, where regulatory requirements directly connect renewable energy development with battery storage.
Five Different BESS Market Models in Latin America
The development of these five countries shows that the Latin American energy storage market is highly diverse.
| Country | Main Driver | BESS Market Model |
| Chile | Renewable curtailment | Curtailment-driven |
| Mexico | Energy policy | Policy-driven |
| Brazil | Capacity auctions | Auction-driven |
| Argentina | Grid constraints | Grid-support-driven |
| Dominican Republic | Storage requirements | Mandate-driven |
This diversity means battery suppliers and project developers cannot assume that one BESS configuration will fit every market.
Project requirements can vary in terms of:
♠Storage duration
♠Power capacity
♠Energy capacity
♠Grid connection
♠Battery technology
♠Inverter or PCS configuration
♠BMS communication
♠Safety requirements
For example, a utility-scale LiFePO4 battery system designed for renewable energy shifting may have very different requirements from a commercial battery used for peak demand management.
What Is the Outlook for Latin America BESS?
The expected increase from 2.5 GW to 34 GW by 2035 highlights the growing importance of battery storage in the region.
For the renewable energy industry, the next stage of development will increasingly connect Latin America solar, solar plus storage and BESS.
Chile, Mexico, Brazil, Argentina and the Dominican Republic demonstrate five different approaches to energy storage deployment. Understanding these market models can help solar and storage companies evaluate where battery energy storage system opportunities are emerging and how project requirements may differ from one country to another.
Conclusion: Latin America BESS Market Outlook
Latin America’s energy storage market is entering a period of rapid expansion, with Chile, Mexico, Brazil, Argentina, and the Dominican Republic developing different pathways for battery energy storage. From renewable curtailment and grid constraints to capacity auctions and mandatory storage requirements, these markets show that BESS is becoming an increasingly important part of the region’s evolving solar market.
For solar wholesalers, distributors, installers, and EPC contractors, understanding these different market models is essential when selecting the right battery energy storage system. Project requirements can vary significantly in terms of storage duration, power capacity, grid connection, system scalability, safety standards, and inverter compatibility.
