Trinasolar said it will work with Atlas Renewable Energy to develop a 233 MW/1,003 MWh grid-forming energy storage system as part of a solar-plus-storage complex in the South American nation. The project, backed by Atlas' recent US$475 million financing, will supply clean power to Chile's mining sector and help strengthen the national grid's stability.

The deal marks another GWh-scale order for Trinasolar's energy storage business as it accelerates expansion into overseas markets.
