CSI Energy Storage, a unit of Canadian Solar, said it will provide 487 MWh of its SolBank energy storage products to Aypa Power, a Blackstone portfolio company that develops, owns and operates utility-scale energy storage and hybrid renewable energy projects across North America.

The energy storage products will be used to support a standalone energy storage project in southern California. The standalone energy storage project is expected to be operational by the first half of 2024. The project will use CSI Energy Storage’s SolBank, which is intended for utility-scale applications. 

Aypa Power had its first energy storage capacity come online in 2018, and currently has more than 15 GW in development across North America.

In September, CSI Energy Storage launched SolBank and announced the expansion of its battery manufacturing capacity from the existing 2.5 GWh to a planned 10 GWh by the end of 2023.

SolBank is a lithium iron phosphate (LiFePO4) chemistry-based battery enclosure with up to 2,800 kWh of energy capacity. It includes liquid cooling and humidity control, and active balancing battery management system technologies.

The battery is produced in Jiangsu Province in China.
