August 15, 2025: Trina Storage said on August 11 it had shipped the first 1.2GWh batch of its self-developed, containerized ‘Elementa 2’ LFP battery storage system to Chile, marking its largest overseas standalone BESS project.

The China-based international renewables developer said the move ushered in a new era of gigawatt-scale international deployments and validated its technical adaptability for operations in extreme environments.

The firm did not disclose the eventual storage capacity of the grid-scale BESS site, in the northern Atacama Desert, which it said was one of the world’s driest and most challenging regions.

According to Trina, Elementa 2 systems are housed in 20ft containers that are equipped with cooling systems that ensure a minimal temperature variation of just 2.5°C.

The company said this is key to ensuring the longevity and efficiency of its systems, together with its own battery management systems.

Trina has invested close to $700 million in R&D since 2021, including over $26 million into dedicated battery cell R&D.

The company said it had shipped more than 10GWh of its proprietary BESS systems to over 100 countries as of the end of last year.

Trina cited data from Chile’s energy ministry indicating that overall operational energy storage capacity in the country reached 3,660 MWh by the first quarter of 2025.
