Canadian Solar's e-STORAGE and ENGIE to Deliver 226 MWh DC of BESS Projects in Scotland

The two BESS projects will utilize e-STORAGE’s SolBank and support more than 40,000 homes while facilitating the UK's transition to net zero emissions by 2050

Canadian Solar’s majority-owned e-STORAGE announced it will construct two energy storage projects, each with a capacity of 56.5 MW / 113 MWh DC, in Cathkin and Broxburn, Scotland, for ENGIE under an Engineering, Procurement, and Construction (EPC) agreement.

The sites, with a combined capacity of 226 MWh DC, will be linked to the 33 kV network and are expected to connect the grid in early 2025.

The two Battery Energy Storage Systems (BESS) projects will employ SolBank, a proprietary containerized energy storage solution, using robust and high-cycle capacity lithium-iron-phosphate (LFP) cells, active balancing battery management system (BMS), and efficient thermal management system (TMS). 

The energy storage projects will not only support more than 40,000 homes but also facilitate the United Kingdom's transition to net zero emissions by 2050.

"Serving alongside ENGIE's 2.1 GW of existing UK pumped storage assets at Dinorwig and Ffestiniog, these projects will build upon ENGIE's position as a leader in power flexibility in the UK,” said Aidan Connolly, Head of ENGIE Battery Storage UK. “ENGIE is targeting 10 GW of global battery storage by 2030 to help facilitate the energy transition, and these two Scottish projects are another step on this journey."
