CSI Energy Storage has entered into a supply agreement with Unibal, a joint venture between Union Group and Capbal Limited, to deliver battery storage systems for two projects totaling 40 MWh in the United Kingdom. The projects are expected to reach commercial operation in Q1 2024.

The battery storage market in the UK has experienced significant growth and holds immense potential for supporting the country’s transition to a low-carbon future and the UK Government’s net-zero targets by 2050. These projects will further contribute to the seamless integration of renewable energy sources, enabling grid operators to efficiently balance supply and demand, and ultimately enhance the stability and reliability of the grid.


Dr. Shawn Qu, Chairman and CEO of Canadian Solar, declared: “Leading renewable energy companies across the world, including Unibal, trust CSI Energy Storage to provide best-in-class energy storage systems. The UK is a major market for energy storage, and CSI Energy Storage is proud to grow our work there through this partnership.”

Unibal Energy Limited is a UK-based company focused on the acquisition, origination, construction, and operation of renewable generation and energy storage assets across the UK. CSI Energy Storage will deliver its SolBank battery energy storage systems and provide full integration and commissioning services. CSI Energy Storage has also secured the long-term service agreements for the projects.


Unibal Chairman, David Fyffe, stated “We wish to congratulate the CSI team on bringing such an impressive BESS offering to market. Our agreement provides a robust platform upon which to construct and operate BESS assets at a significant scale.” 

CSI Energy Storage now has executed agreements to deliver 779 MWh of energy storage solutions to projects throughout the United Kingdom. CSI Energy Storage has deployed around 2.7 GWh of battery energy storage solutions to date across the United States, Canada, the United Kingdom, and China. As of March 31, 2023, CSI Energy Storage’s total pipeline has reached nearly 22.8 GWh.
