Blackstone portfolio company Aypa Power has selected Canadian Solar’s e-STORAGE to provide a 498-megawatt hour (MWh) battery storage system for the Bypass project being developed in Texas, the solar company said July 9.

Located in Fort Bend County, the Bypass project will use 106 units of e-STORAGE’s SolBank 3.0 paired with 65 power conversion systems and controllers. The units feature high-density lithium-iron-phosphate chemistry battery cells.

The project is expected to be complete in third-quarter 2025.

The contract is the third between Aypa Power and e-STORAGE, which is part of Canadian Solar’s majority-owned subsidiary CSI Solar Co. Ltd.

“This brings our total commitment to providing Aypa with over 1.3 GWh of integrated energy storage capacity,” said Colin Parkin, president of e-STORAGE.

The company also said it will provide ongoing operational support for the project under a long-term service agreement.
