Canadian Solar Inc. (NASDAQ: CSIQ) announced that its energy storage subsidiary, e-STORAGE, has signed an agreement to supply and commission a 100 MW/200 MWh battery energy storage system (BESS) for OX2's Muswellbrook Solar Farm and Battery project in New South Wales, Australia.

The system will be built on e-STORAGE's SolBank 3.0 battery containers, paired with Power Conversion Systems, plant controls, and the company's proprietary EQ-S Energy Management System. e-STORAGE will also supply a hybrid power plant controller to coordinate the battery with the co-located solar farm and lead overall integration and commissioning.

Shipments are scheduled to begin in Q3 2027, with commercial operation targeted for Q3 2028. Battery cells and the SolBank system will be manufactured at Canadian Solar's own facilities. The agreement includes a 20-year long-term service agreement covering hardware, software, and performance.

The project is located approximately 2.5 kilometers east of Muswellbrook, on land at a former coal mine within the Hunter-Central Coast Renewable Energy Zone. Once operational, the system will support a long-term hybrid power purchase agreement OX2 has signed for the project.

Jeff Roy, President of e-STORAGE, said: "Australia's energy transition is being decided in regions like the Hunter, where storage now has to carry the load that retiring coal once did. We control this project from the cell through to our own energy management software and 20 years of service, which means OX2 has one partner accountable for how the system performs over its full life."

Steve Symons, Vice President of OX2 Australia, said: "This battery storage system is what turns Muswellbrook into a true hybrid facility — pairing solar generation with storage so we can capture energy when the sun is shining and deliver it when the grid needs it most."
