Chinese energy storage leader BYD Energy Storage has clinched another major international contract, this time supplying 2.6GWh of battery storage systems for the Central Chile Oasis solar-storage project. The deal, sealed with Spanish clean energy giant Grenergy, marks the second large-scale cooperation between the two companies within a year and further consolidates BYD’s expanding footprint in Latin America’s renewable energy sector.

Under the new agreement, BYD will deliver 468 units of its MC Cube-T liquid-cooled energy storage systems, representing a total capacity of 2.6GWh. The equipment will be deployed across four solar-storage plants that form the Central Chile Oasis initiative: Gran Teno, Tamango, Planchón, and Monte Águila. The project is designed as a replica of the successful Atacama Oasis model, combining large-scale photovoltaic generation with advanced battery storage to ensure stable and clean electricity supply for central Chile.

The latest partnership builds on the previous collaboration announced in May 2025, when BYD and Grenergy joined forces to deliver 3.5GWh of storage—at the time the largest energy storage project in Latin America, located in the Atacama region. With this new 2.6GWh commitment, the two companies are deepening their strategic alliance to accelerate the region’s energy transition.

According to project details shared by the developers, the Central Chile Oasis complex will feature a total solar photovoltaic capacity of 1.1GW combined with 4GWh of energy storage. Total investment is estimated at US$900 million, and the project is scheduled to reach full commercial operation between 2026 and 2027. BYD’s portion covers the majority of the storage capacity needed for the four interconnected plants, highlighting the trust Grenergy places in BYD’s technology and execution capabilities.

“At this critical stage of the global energy transition, we are deeply honored to walk side by side with a world-class partner like BYD Energy Storage. BYD’s technical strength and product quality are key pillars supporting our energy network upgrade. From the Atacama Oasis in northern Chile to this Central Oasis expansion, we are steadily advancing the global rollout of the ‘Oasis model.’ In the future, we will continue leveraging the advantages of our partnership to promote this mature solar-storage integration model to Spain and other global markets, jointly building a more flexible, efficient, and sustainable new energy system.”

In a recent operational update, BYD confirmed that 168 of the energy storage cabinets designated for the Gran Teno plant have already been loaded onto vessels at the port of Shenzhen. These units are expected to arrive at the project site by mid-April, with the remainder of the equipment following according to the scheduled shipping plan. Gran Teno is on track to achieve grid connection and begin commercial operation in the second quarter of this year, making it the first of the four plants to come online.

“It is a great honor to continue deepening our cooperation with Grenergy and jointly advance two landmark projects—the Atacama Oasis and the Central Oasis. Since BYD introduced its ‘Three Major Green Dreams’ vision, we have remained committed to the research, development, and application of energy storage technologies, striving to contribute Chinese solutions to the global energy transition. With this collaboration, we will deploy our leading storage technologies and full-chain services to ensure the smooth execution of the Central Oasis project, injecting strong momentum into the clean energy development of Chile and the wider Latin American region. We appreciate Grenergy’s long-term trust and look forward to creating more cooperation benchmarks in the global renewable energy space as we work together toward a green, low-carbon future.”

Industry analysts view the repeated collaboration as a strong endorsement of BYD’s vertically integrated supply chain and its ability to deliver turnkey storage solutions at scale. BYD Energy Storage has spent 18 years building a comprehensive global service network that covers sales, delivery, commissioning, operation, and after-sales support. As of the end of 2025, the company’s cumulative energy storage system shipments surpassed 135GWh, with more than 650 successfully executed projects across over 110 countries and regions.

The 2.6GWh win not only reinforces BYD’s leading position in the Latin American storage market but also demonstrates how Chinese energy storage manufacturers are becoming indispensable partners in large-scale international renewable infrastructure. With the Central Oasis project now advancing rapidly, both Grenergy and BYD are poised to replicate the integrated “Oasis” blueprint across additional markets, including Spain and other parts of Europe, where hybrid solar-storage plants are increasingly seen as a backbone for grid stability and decarbonization.

Meanwhile, Grenergy continues to expand its renewable portfolio across Latin America and Europe. The company has highlighted that replicating the Atacama Oasis concept in central Chile will help stabilize the region’s grid, which faces rising energy demand and a growing share of intermittent renewables. The 4GWh total storage capacity of the Central Oasis project will enable large-scale solar energy shifting, reduce curtailment, and deliver reliable power even after sunset.
