Trina Storage, the energy storage division of Trinasolar, and Atlas Renewable Energy have joined forces to deliver one of the most advanced energy storage systems in Latin America: the Copiapó PV + BESS Project , a 233 MW / 932 MWh grid-forming (GFM) facility located in the Atacama Region of Chile. This pioneering grid -forming technology project will mark a milestone in the stability and resilience of the Chilean National Electric System.
With the rapid growth of solar and wind energy across Latin America, ensuring grid stability has become a key challenge. Therefore, grid-forming energy storage will become vital for maintaining the reliability of the electrical system. This project will be developed in accordance with upcoming BESS technical regulations in Chile, positioning itself as a benchmark for other markets in the region. Unlike traditional grid-following systems, which only shift and manage energy, this project will actively support the grid by responding quickly to power disturbances, improving the reliability of the country’s National Electric System.
This large-scale solar and storage complex will be financed with USD 475 million by Atlas Renewable Energy, supplying clean energy to the Chilean mining sector and strengthening the resilience of the national grid.
The Elementa 2 storage solution from Trina Storage, selected for this project, is designed for extreme environments like the Atacama Desert, combining high energy density, long lifespan, advanced security, and optimized maintenance, guaranteeing reliable performance under demanding conditions. The project will also serve as a technical benchmark for other Latin American markets closely monitoring the progress of Grid Forming regulations and the deployment of BESS in the region.
“This large-scale project will showcase Trina Storage’s grid-forming technology, improving grid stability in Chile,” said Vicente Walker, director of Trina Storage LATAM. “It also marks another important step in our regional growth, adding to the 1.2 GWh already shipped in 2025 and more than 2.5 GWh in contracts signed for 2026 in Chile, Argentina, and Central America.”
To better serve the Latin American market, Trina Storage has strengthened its local service capabilities and regional technical expertise. Its teams in each country ensure compliance with local grid codes, regulatory standards, and financing requirements—advantages further enhanced by its collaboration with Atlas Renewable Energy.
Trina Storage will also support the project from the manufacturing of LFP battery cells through on-site supervision, commissioning, and long-term service, with dedicated personnel on site. This approach highlights the company’s vertically integrated model and its role as a comprehensive technology partner.
With the Copiapó PV + BESS Project , Trina Storage reinforces its leadership in bankable large-scale storage solutions, driving a clean, resilient and sustainable energy future for Latin America.
