Trina Storage, Trina Solar’s utility-scale energy storage business, has signed new contracts in Chile and Argentina totaling 1,203 MWh of battery energy storage systems (BESS). The agreements include 722 MWh in Chile with T-Power, the energy platform of Toesca Asset Management, and 481 MWh in Argentina with YPF Luz.
With these contracts, Trina Storage adds to the 1.2 GWh already delivered in Latin America in 2025 and expects a further 2.5 GWh to be delivered in the first half of 2026.
The company said it ranks among the top five BESS suppliers in South America, offering end-to-end solutions that include battery systems, power conversion systems (PCS), medium-voltage equipment, and SCADA platforms for grid integration.
In Chile, the project will be deployed at the Luz del Norte BESS, located in Copiapó, Atacama Region, alongside the 141 MW Luz del Norte photovoltaic plant, acquired by T-Power in 2023 from First Solar. The storage system will have a nominal power of 141 MW and a capacity of 722 MWh, using 144 Elementa 2 containers. The BESS will optimize PV plant operations, reduce curtailment, and enable nighttime energy trading.
In Argentina, Trina Storage signed an agreement with Central Dock Sud, controlled and operated by YPF Luz, for the Alma Sur BESS, part of the AlmaGBA program. The facility will have a capacity of 90 MW / 481 MWh, using 96 Elementa 2 containers, and is designed to strengthen seasonal power supply in the Buenos Aires Metropolitan Area (AMBA).
