ENGIE has signed a deal with Canadian Solar’s e-Storage to construct two 50MW/100MWh, two-hour duration battery sites in Scotland.

The projects will both be located at greenfield sites, with one situated in Cathkin (south of Glasgow) and the other in Broxburn (west of Edinburgh).

Construction is scheduled to commence in Q1 next year, with both sites expected to be fully operational in Q1 2025, with a connection to SP Energy Network’s 33kV distribution network.

Both projects will help ENGIE towards its 10GW target of battery storage globally.

Aidan Connolly, head of battery storage UK at ENGIE, stated that the utilities company was looking forward to working with Canadian Solar on the construction of the project, having signed two energy performance certificate (EPC) contracts for both 50MW/100MWh sites.

Canadian Solar’s e-Storage – previously CSI storage – is a subsidiary of the company’s manufacturing division, that launched it’s utility-scale energy storage product, SolBank in September 2022.

Renewable energy investor Copenhagen Infrastructure Partners (CIP), recently confirmed that SolBank will be the technology used for its 500MW/1,000MWh battery energy storage system (BESS) in Scotland.

This article has been amended to reflect the expected start of operations for both projects will be in early 2025.
