ENGIE signs a deal with Canadian Solar’s e-STORAGE

ENGIE signs a deal with Canadian Solar’s e-STORAGE to bolster UK grid flexibility with two battery projects in Scotland.

These projects act to accelerate ENGIE’s commitment of reaching 10 GW of battery storage globally and empower renewable energy growth in the UK. 

ENGIE is pleased to announce a significant milestone in its ambition to increase flexible generation capacity by signing a deal with Canadian Solar’s e-STORAGE to build two 50 MW 2 hour duration battery sites in Scotland. 

The projects are located at greenfield sites in Cathkin (South of Glasgow) and Broxburn (West of Edinburgh). Construction is scheduled to begin in Q1 2024, and they are expected to be fully operational in Q1 2025, connecting into SPEN’s 33kV distribution network.  


Alongside ENGIE’s existing 2.1 GW of pumped storage assets in the UK, a growing BESS portfolio will strengthen ENGIE’s leading position in energy storage and flexibility in the UK. It will also bolster the Group’s contribution to the reliability and efficiency of the UK grid infrastructure, providing the necessary flexibility during times of increasing energy demand and aid the transition to renewable energy sources. 

ENGIE has selected Canadian Solar’s e-STORAGE as a delivery partner for these projects due to their track record, proven expertise in battery storage, and commitment to health and safety as number one priority. 

“At ENGIE, we're excited to work with Canadian Solar's e-STORAGE and are pleased to have signed EPC contracts for our two 50 MW / 100 MWh BESS projects at Cathkin and Broxburn in Scotland. We are looking forward to the construction stage of this project, and are happy to be working with a company with the technical solution and delivery capabilities of Canadian Solar, who are also aligned with our commitment to a high standard of Health and Safety.” – Aidan Connolly, Head of Battery Storage UK.
