Denmark-headquartered investor Copenhagen Infrastructure Partners (CIP) has brought its 500MW, 2-hour duration Coalburn 1 battery energy storage system (BESS) into commercial operation.
Coalburn 1 is located in South Lanarkshire, southern Scotland, on the site of a former coal mining community. The lithium-ion project was developed by CIP through its flagship Copenhagen Infrastructure IV fund, in partnership with UK developer Alcemi.
The BESS was supplied by Canadian Solar’s e-STORAGE subsidiary under a contract covering 1,170MWh DC of its SolBank battery technology, along with full integration, commissioning and long-term operational services.
