Copenhagen Infrastructure Partners invests €270m in Scottish battery project

Copenhagen Infrastructure Partners (CIP) has reached a final investment decision to invest €270 million (£232 million) in the Kilmarnock South battery energy storage system (BESS) in South Ayrshire, Scotland. The project, developed by Noriker Power, will feature a 350 MW power rating and a 1,400 MWh capacity, providing four hours of energy storage.

Construction is already underway, with commercial operations expected to begin in the first quarter of 2028. The system is designed to store surplus wind energy generated in Scotland and supply it to the grid during periods of high demand. Shell is expected to optimize the project under a deal that likely includes contracted revenues.

Kilmarnock South marks CIP’s fourth large-scale BESS investment in Scotland, joining the Coalburn 1, Coalburn 2, and Devilla projects. Once all four are fully operational, the portfolio will provide a total storage capacity of 4.4 GWh, representing nearly one-third of the current battery storage capacity in Great Britain.
