Covering Disruptive Technology Powering Business in The Digital Age

Canadian Solar Inc. has announced that e-STORAGE, which is part of the company’s majority-owned subsidiary CSI Solar Co., Ltd. (“CSI Solar”), has been selected as the preferred supplier for Engineering, Procurement, and Construction (“EPC”) and Operations and Maintenance (“O&M”) by Copenhagen Infrastructure Partners (CIP) to deliver its Summerfield battery storage project in South Australia.

The Summerfield battery storage project is a two-hour 240 MW (480 MWh) DC energy storage solution. The project is currently sized at a two-hour storage duration but is expandable depending on market needs. Summerfield is the first of multiple large-scale battery projects spearheaded by CIP in Australia. The project is scheduled for installation in 2025 and will incorporate e-STORAGE’s SolBank battery technology.

The Summerfield Battery is strategically situated in the Murraylands region to the east of Adelaide in South Australia.  The battery supports Australia’s energy operator’s roadmap for the efficient development of the network and facilitates the integration of new renewable generation sources.

A Critical Energy Reservoir Once Operational

Using e-STORAGE’s proprietary SolBank’s cutting-edge battery technology, the Summerfield Battery will serve as a critical reservoir of energy, enhancing grid stability in the region. The battery system will accumulate surplus energy during periods of low demand and distribute power back to the grid during peak consumption phases. This functionality is essential for ensuring a consistent, cost-effective supply of electricity to South Australia, Victoria, and the broader national energy grid.

“We are pleased to work with Canadian Solar to deliver a new large-scale battery in South Australia. The Summerfield Battery will help to ensure continued energy reliability and unlock new renewable capacity,” said Jørn Hammer, Partner and Head at CIP Australia.

Colin Parkin, President at e-STORAGE, added: “We are deeply honored to collaborate with Copenhagen Infrastructure Partners Flagship Fund as they endeavor to expand battery storage solutions in Australia. Together, we understand the pivotal role that battery storage systems play in achieving a sustainable future and we are engaged in making a difference in the renewable industry.”

e-STORAGE will deliver its proprietary SolBank battery energy storage systems and provide full integration, commissioning, and long-term operational services for the project.

SolBank is a self-manufactured battery designed for utility-scale applications. It is based on lithium-iron-phosphate (LFP) chemistry and engineered with a strong focus on safety and efficiency. The battery incorporates LFP cells, efficient liquid cooling systems, and multi-level fire safety management systems. It also includes state-of-the-art monitoring and control systems.

Additionally, the active cell balancing system ensures safe operation and optimised system efficiency and overall performance.
