Canadian Solar to provide 75 MW/300 MWh energy storage system in Mustang solar project

Canadian Solar Inc. has closed a supply contract and long term service agreement with Goldman Sachs Renewable Power LLC, part of the Renewable Power Group of Goldman Sachs Asset Management, to deliver and integrate a 75 MW/300 MWh lithium-ion battery storage solution into the 100 MWac Mustang solar plant in California.

The 75 MW or 4-hour 300 MWh energy storage system is a retrofit addition to the Mustang solar plant in King's County, California, which was originally developed by Canadian Solar's wholly owned subsidiary Recurrent Energy, LLC ("Recurrent Energy"). The solar plant was connected to the grid in August 2016 and the project's equity stake was later sold to Goldman Sachs in May 2019.

Canadian Solar will provide the complete integrated solution, including a lithium iron phosphate-based technology package, and all future operations, maintenance, and battery augmentation services. In addition, the Company will support the storage solution with fully wrapped capacity and performance guarantees, ensuring system output, reliability, and safety.

Construction of the energy storage component of the project will begin in early 2021 and is expected to be operational by the second half of 2021.
