Multiple BESS deals followed, including 1,858 MWh in Ontario and 56 MWh in Germany, plus an 800 MW UK solar and 1,000 MWh storage project. A Dec 1 update detailed resuming direct oversight of U.S. manufacturing. Today’s Australian 408 MWh project continues this theme of expanding global storage footprint.
Market Pulse Summary
This announcement adds a 204 MW / 408 MWh AC BESS contract in South Australia, further growing e-STORAGE’s approximate 2 GWh footprint in the country and marking its fourth Australian project. It extends Canadian Solar’s global storage build-out alongside recent UK, German, and Canadian projects. Investors may track execution toward the 2027 operation target, performance under the initial 5-year LTSA, and how these long-duration contracts complement prior milestones such as the Q3 2025 e-STORAGE shipment record.
