Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ:CSIQ) today announced that e-STORAGE, its energy storage solutions business, and Sunraycer, a leading developer, owner, and operator of clean energy power sites, have entered into agreements for the supply and long-term servicing of two standalone battery energy storage projects totaling 503 MWh DC in Franklin County, Texas.

The projects, collectively referred to as the Lupinus projects, are being developed by Sunraycer. They comprise Lupinus 1, a 202 MWh facility expected to begin construction in Q1 2027 and reach commercial operation in Q3 2027, and Lupinus 2, a 301 MWh facility scheduled to start construction in Q3 2026 and achieve commercial operation in Q2 2027.

Under the agreements, e-STORAGE will deliver its SolBank 3.0 battery energy storage system and provide 10 years of long-term services, supporting system reliability, performance optimization, and availability throughout the project lifecycle. The battery cells integrated into SolBank 3.0 are manufactured within Canadian Solar's global manufacturing network, reinforcing supply chain resilience and long-term operational reliability at scale.

The Lupinus projects will play a vital role in supporting renewable energy integration and enhancing grid stability within the ERCOT market, one of North America's fastest-growing and most dynamic energy storage markets. This collaboration reflects both companies' shared commitment to deploying secure, scalable, and efficient energy storage solutions that enable a more flexible and resilient power grid.
