Strategically located in Fort Bend County near Thompsons, Texas, the Bypass Project will support the growing energy demand of the greater Houston area. It will utilize 106 units of e-STORAGE's latest battery energy storage solution, SolBank 3.0.

Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) today announced that e-STORAGE, which is part of the Company's majority-owned subsidiary CSI Solar Co., Ltd. ("CSI Solar"), has secured a contract from Aypa Power ("Aypa") to deliver a 498 MWh DC standalone battery energy storage system for Aypa's Bypass Project. The Bypass Project is scheduled for completion in the third quarter of 2025.

Strategically located in Fort Bend County near Thompsons, Texas, the Bypass Project will support the growing energy demand of the greater Houston area. It will utilize 106 units of e-STORAGE's latest battery energy storage solution, SolBank 3.0. The batteries will be paired with 65 power conversion systems and controllers. Each SolBank battery delivers 5 MWh of energy capacity in a 20-foot standardized container, featuring high-density lithium-iron-phosphate (LFP) chemistry battery cells, an active balancing battery management system, and an innovative liquid cooling thermal management system to enhance operational efficiency, safety, and reliability.

After integrating and commissioning the project to commercial operation, e-STORAGE will provide ongoing operational support for the project under a Long-Term Service Agreement (LTSA).

Moe Hajabed, CEO of Aypa Power, commented, "We are pleased to continue our partnership with e-STORAGE on the Bypass Project.
