Chinese energy storage leader BYD Energy Storage has secured another major international contract, this time to supply 2.6GWh of battery storage systems for the Central Chile Oasis solar-storage project. The agreement, signed with Spanish clean energy giant Grenergy, marks the second large-scale collaboration between the two companies within a year and further strengthens BYD’s growing presence in Latin America’s renewable energy sector.

Under the new deal, BYD will deliver 468 units of its MC Cube-T liquid-cooled energy storage systems, totaling 2.6GWh. The equipment will be installed across four solar-storage plants that make up the Central Chile Oasis initiative: Gran Teno, Tamango, Planchón, and Monte Águila. The project follows the model of the successful Atacama Oasis, combining large-scale solar generation with advanced battery storage to deliver stable, clean electricity to central Chile.

This latest partnership builds on a previous collaboration announced in May 2025, when BYD and Grenergy teamed up to supply 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 help accelerate the region’s energy transition.

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

David Ruiz de Andrés, CEO of Grenergy, stated:”At this critical stage in the global energy transition, we are deeply honored to work alongside 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 to leverage our partnership to promote this mature solar-storage integration model to Spain and other global markets, jointly building a more flexible, efficient, and sustainable 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 remaining equipment to follow according to the planned shipping schedule. 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.

Yin Xueqin, General Manager of BYD Energy Storage & New Battery Division, remarked:“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. Through 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 broader 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 covering sales, delivery, commissioning, operation, and after-sales support. As of the end of 2025, the company’s cumulative energy storage system shipments exceeded 135GWh, with more than 650 successfully executed projects across over 110 countries and regions.

The 2.6GWh order not only reinforces BYD’s leading position in the Latin American storage market but also highlights 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 well positioned to replicate the integrated “Oasis” blueprint in 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 noted 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.
