CIP Invests EUR 270 Million in Scottish Battery Storage Project

Copenhagen Infrastructure Partners (CIP) has finalized a significant investment of EUR 270 million for the Kilmarnock South battery energy storage system (BESS) located in southern Scotland. Construction is underway, with commercial operations expected to commence in the first quarter of 2028.

The 350 MW, four-hour duration facility is poised to become the longest-duration battery asset in CIP's UK storage portfolio. It is designed to capture surplus wind power that might otherwise go unused and release it to the grid during periods of high demand, thereby enhancing the UK's energy security and grid stability.

Nischal Agarwal, Partner at CIP, highlighted the project's role in maximizing the benefits of renewable energy. "Well-sited battery energy storage projects provide valuable power system flexibility which enables the full benefits of low-cost renewables to be captured, strengthening security of supply and helping to both cut and stabilise energy bills for consumers," Agarwal stated.

Kilmarnock South marks CIP's fourth major battery investment in Scotland, joining existing projects such as Coalburn 1, Coalburn 2, and Devilla. Upon completion of all its Scottish projects, CIP's portfolio will collectively offer 4.4 GWh of energy storage capacity, representing a substantial contribution to Great Britain's overall battery storage infrastructure.
