Canadian Solar, through its subsidiary CSI Energy Storage ( a majority-owned subsidiary of CSI Solar Co., Ltd.), has signed an agreement to deliver 49.5MW/99MWh of turnkey battery energy storage solutions to Cero Generation (Cero) and Enso Energy (Enso), two prominent players of the European solar energy market specializing in solar energy development, production and storage. 


Cero has one of the largest development portfolios in Europe aggregating 11 GW, covering utility-scale solar and integrated energy storage solutions. Together with Enso, Cero will use CSI Energy Storage’s SolBank products for their 49.5MW/99MWh battery energy storage system. The energy storage system will be based in South Gloucestershire, United Kingdom, which is also the home of the Larks Green solar PV project. The first transmission-connected solar farm in the UK, the Larks Green Solar PV is owned and operated jointly by Cero and Enso. The energy delivery started in May 2023.

CSI Energy Storage will provide comprehensive services, including commissioning, integration, long-term operations, maintenance, and performance guarantees. The projects are slated for commercial operation by late 2024. As of March 31, 2023, CSI Energy Storage has a total pipeline of 22.8 GWh.

Speaking about the development, Marta Martinez Queimadelos, CEO of Cero Generation, said, “We’re thrilled to have established a strong and long-term partnership with CSI Energy Storage through this project, which will be our first battery energy storage system to enter the construction phase. We’re looking forward to growing this relationship as we commercialize our pipeline of energy storage projects across Europe.”

Ian Harding, Director of Enso Energy, noted: “At Enso Energy we are really pleased that we are now able to work with Canadian Solar to build upon the success of Larks Green being the first UK transmission connected solar farm. Adding Canadian Solar’s battery energy storage systems at the site will further optimize the use of the land as well as the grid connection there and be able to provide the electricity grid with more of the flexibility it desperately needs to transition to net zero.”

Dr. Shawn Qu, Chairman and CEO of Canadian Solar, said “We are proud to support Cero Generation as they develop the storage projects needed to support Britain’s energy transition. To date, CSI Energy Storage has deployed around 2.7 GWh of battery energy storage solutions across the UK, U.S., Canada, and China, and has now executed agreements to deliver 739 MWh of energy storage solutions to projects throughout the UK.”
