Copenhagen Infrastructure Partners (CIP) has acquired the 350 MW Kilmarnock South battery storage project in South Ayrshire, Scotland, it is understood.

The investor is mooted have completed the purchase on behalf of its EUR 7bn Copenhagen Infrastructure IV vehicle in late January, according to company records.

The Kilmarnock scheme was originally developed through a joint development platform between Noriker Power and Equinor but was expected to have been taken forward by the former group in the wake of a spring 2025 management buyout of Equinor’s minority stake.

However, a paper trail of current records still lists Equinor as a shareholder in the two-hour duration BESS, with the Norwegian group understood to have retained an economic interest in the asset in order to access a portion of future sales proceeds despite deferring responsibility for the disposal entirely to Noriker.

The project is located on land north of Camsiscan Farm in Craigie, approximately 1.7 km from the Kilmarnock South substation, and occupies around 13.45 hectares of agricultural land.

The consented development comprises approximately 392 battery containers arranged across nine terraced platforms, alongside inverters, transformers and a 400 kV high‑voltage switchgear compound.

Electricity export is designed through an underground cable route connecting the site directly to the Kilmarnock South substation, with installation largely following the public highway network.

Planning consent for the project was granted by the Scottish Government’s energy consents unit in January 2024.

Equinor originally acquired its stake in Noriker in late 2021 but the pair went their separate ways in April 2025.

Noriker subsequently secured a GBP 15m financing facility from Triple Point to support the development of a wider 2.2 GW pipeline of battery storage projects across the UK and Ireland.

The Kilmarnock South project was previously understood to be included within the portfolio supported by the Triple Point facility and was expected to energise in the fourth quarter of 2026, in-line with a late-2026 grid connection date previously allocated to the developers to hook up to the transmission network.

CIP declined to comment, while Noriker and Equinor were also contacted.
