e-STORAGE, a subsidiary of Canadian Solar, has secured a contract from Chile-based power generation company Colbún to supply a 228MW/912 megawatt-hour battery energy storage system (BESS) for the Diego de Almagro Sur project in the Atacama Region of Chile.
The Diego de Almagro Sur BESS project will feature e-STORAGE’s proprietary SolBank 3.0 battery energy storage solution, which includes lithium-iron-phosphate battery technology, an active balancing battery management system and a liquid cooling system.

The high efficiency and safety profile of the SolBank 3.0 are designed to minimise the environmental footprint, aligning with Colbún’s sustainability objectives and ensuring the long-term performance of the system.
e-STORAGE will provide Colbún with a comprehensive solution encompassing project management, commissioning services and long-term maintenance.
The construction of the BESS is set to commence in June 2025, which is expected to create up to 150 jobs at its peak. The project is set for commercial operation in December 2026.
Colbún CEO José Ignacio Escobar said: “This agreement with e-STORAGE positions us as one of the leading companies in Chile’s energy storage market, ensuring a continuous and secure supply of renewable energy for our industrial clients.

By GlobalData“This project, together with the other battery systems we are developing in the north of the country, will complement the storage capacity we already have through our reservoirs in the south. It is aligned with our vision of driving a responsible energy transition, where renewable energy must be not only sustainable but also secure, continuous and competitive.”
The BESS system will be integrated with the existing 232MW Diego de Almagro Sur Solar Park, which Colbún has operated since 2022.
The project will have the capacity to supply electricity equivalent to that consumed by 55,480 households.
The BESS project will not only offer energy shifting and capacity contribution but also advanced grid services such as grid forming, black start and inertia support, which are vital for incorporating more renewable energy sources into Chile’s national grid.
e-STORAGE president Colin Parkin said: “The Diego de Almagro Sur BESS Project represents a significant milestone for e-STORAGE’s expansion in Latin America and reinforces our role as a key enabler of Chile’s clean energy transformation.
“This project showcases the critical role of BESS in enabling greater grid reliability, optimising renewable energy usage, and supporting industrial demand with a secure and continuous supply. With our SolBank 3.0 technology, we are not only delivering cutting-edge performance and safety but also reinforcing our long-term commitment to Latin America’s clean energy future.”
Earlier this month, Canadian Solar agreed to supply its anti-hail module technology to Flow Power’s solar and BESS project in the Coonawarra wine region of South Australia.
