Canadian Solar’s majority-owned subsidiary, CSI Solar Co., has got a contract to supply a 350 MW/1,400 MWh fully integrated battery storage system to the Crimson stand-alone battery storage project in Riverside County, California. CSI will also provide EPC and long-term maintenance services as part of the contract.

The Crimson storage project has two owners: Axium Infrastructure with 80 per cent ownership and Recurrent Energy, Canadian Solar’s wholly owned subsidiary with 20 per cent. The Crimson project has two 15-year stand-alone storage contracts with local utilities Southern California Edison and Pacific Gas and Electric. These contracts are a part of the California Public Utilities Commission’s reliability procurements.

CSI Solar’s integrated solution includes a lithium iron phosphate-based technology battery system. The project is expected to reach commercial operation by the summer of 2022. After commissioning, CSI Solar will provide maintenance services for 15 years to ensure system output, safety, and reliability. Moreover, this long-term service agreement not only includes the operation and maintenance of the battery systems but also future augmentation services. Additional installed battery capacity of approximately 300 MWh are planned to be installed over regular time periods for project augmentation.

REGlobal’s Views: California is witnessing a massive uptake of energy storage systems in the recent months. This is primarily driven by the states’ requirement for high quality grid balancing reserves that can help address the intermittency issues caused by a high penetration of solar and wind energy in the states’ energy mix.
