Canadian Solar's e-STORAGE to Deliver 498 MWh DC of Battery Storage Solutions for Aypa Power's Bypass Project in Texas

Canadian Solar, Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) 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. Utilizing their SolBank 3.0 technology, this project will enhance grid resiliency and support Houston's growing energy needs. This collaboration underscores Aypa's commitment to deploying efficient and dependable energy solutions. We look forward to the Bypass Project's successful delivery and the positive impact it will have on strengthening the Texas grid."

Colin Parkin, President of e-STORAGE, added, "We are excited to announce our third project with Aypa Power by extending our partnership with the award of their Bypass Project. This brings our total commitment to providing Aypa with over 1.3 GWh of integrated energy storage capacity. Our ongoing collaboration with Aypa highlights our commitment to delivering innovative and sustainable energy storage solutions, meeting the diverse needs of our partners' projects and communities."
