Press Releases — Grenergy acquires 2.6 GWh of batteries from BYD Energy Storage for Central Oasis

• A total of 468 MC Cube T batteries will be deployed across four phases of its platform in Central Chile: Gran Teno, Tamango, Planchón, and Monte Águila
• The vessel Star Loen has departed from Da Chan carrying 168 batteries for Gran Teno, where foundation works to connect the batteries in Q2 are already underway

Madrid, March 26, 2026. Grenergy has signed a new agreement with BYD Energy Storage, a global energy solutions company, to supply 2.6 GWh of energy storage systems for its Central Oasis platform, located in central Chile.

Both companies are strengthening their partnership with this new purchase of 468 MC Cube T batteries, which feature the renowned Blade Battery technology. This agreement is in addition to the purchase made in May 2025 of 624 batteries (3.5 GWh) for Elena, phase VI of Oasis de Atacama, which was the largest supply of batteries in Latin America and the second largest worldwide last year.

The 468 batteries will be allocated to phases I, II, III, and IV of Central Oasis: Gran Teno (241 MW of solar capacity and 939 MWh of storage), Planchón (108 MW and 402 MWh), Tamango (49 MW of solar capacity and 168 MWh of storage), and Monte Águila (340 MW of solar capacity and 1.1 GWh of storage).

The Star Loen vessel has already departed from Da Chan carrying the 168 batteries destined for the Gran Teno plant, and it is expected to arrive in mid April. On site, foundation works are progressing to enable its connection during the second quarter of this year.

Grenergy recently announced the closing of a $355 million senior non-recourse financing for the construction of Teno, Tamango and Planchón plants, signed with an international syndicate of banks led by BNP Paribas and also involving Banco Santander and Rabobank.

Central Oasis platform and expansion of the Oasis model

Central Oasis platform has a solar capacity of 1.1 GW and 4 GWh of storage, with an estimated investment of $900 million. Operations are expected to begin between 2026 and 2027.

Central Oasis was created with the aim of replicating the successful solar-storage hybrid model developed by Grenergy at Oasis de Atacama, one of the largest battery platforms in the world and the first in Latin America.

David Ruiz de Andrés, CEO of Grenergy, said:

We are delighted to have a strategic partner of the caliber of BYD, joining us on our journey to build more flexible and efficient networks through energy storage. We continue to expand the platform we started in northern Chile with Oasis de Atacama, now extending to central Chile with Central Oasis. We aim to replicate this model in other markets, including Spain.

Yin Xueqin, General Manager of Energy Storage and New Application Battery Division, BYD, said:

We are truly honored to advance the Oasis de Atacama and Central Oasis in collaboration with Grenergy. Through our energy storage technologies, we aim to contribute our part to a more sustainable future. We sincerely appreciate Grenergy’s continued trust and partnership throughout this journey and look forward to continued collaboration on more renewable projects in the future.
