Copenhagen Infrastructure Partners has committed more than €270 million ($303.7 million) to Kilmarnock South, a 350 MW/1,400 MWh lithium-ion battery in South Ayrshire, Scotland, through its Copenhagen Infrastructure IV fund. Construction is now underway, with commercial operation expected in the first quarter of 2028.
The project was developed by UK-based Noriker Power, which will continue to manage construction. CIP said the project has an optimization agreement with Shell Energy Europe that will provide long-term contracted revenue. CIP did not name the battery supplier or disclose the terms of the Shell agreement.
The project is separate from Zenobē’s 300 MW/600 MWh Kilmarnock South battery, which began commercial operation in January.
CIP said the battery will store surplus Scottish wind power that would otherwise go unused and release it when the grid has capacity. It is CIP’s fourth transmission-connected BESS investment in Scotland, joining Coalburn 1, which began commercial operation in August, and Coalburn 2 and Devilla, both under construction. Together, the four projects total 1.85 GW/4.4 GWh, which CIP said is equivalent to almost a third of Great Britain’s operational battery storage today.
Nischal Agarwal, a partner at CIP, said well-sited battery projects provide system flexibility that lets consumers capture the full benefit of low-cost renewables, strengthening security of supply and helping to cut and stabilize energy bills.
UK Energy Minister Michael Shanks said the Coalburn and Kilmarnock South projects mean less domestically generated power going to waste, greater energy security, and lower bills over the long term.
Coalburn 1, Coalburn 2, and Devilla are each 1 GWh projects developed with CIP’s local partner Alcemi, with battery systems supplied by e-STORAGE, a subsidiary of Canadian Solar. CIP sold a 50% stake in Coalburn 1 to insurer Axa IM Alts in April 2025.
