Burges Salmon advises Copenhagen Infrastructure Partners on investment in Kilmarnock South

We have advised Copenhagen Infrastructure Partners (CIP), a global fund manager and leading investor in energy infrastructure, on an investment in Kilmarnock South and subsequent procurement of supply and works arrangements.

Kilmarnock South is a Battery Energy Storage System (BESS), which includes a 350 MW/1,400 MWh lithium-ion BESS, located in south Ayrshire, southern Scotland. BESS’ are energy infrastructures that aim to store electrical power in large rechargeable batteries and release it back into the electrical grid when demand is high. In this case, the battery will store surplus Scottish wind power that would otherwise go unused and release it to the grid when the network has capacity.

The Financial Investment Decision (FID) took place through CIP’s fourth flagship fund, Copenhagen Infrastructure IV (CI IV), and includes EUR 270 million for the already under construction project, with commercial operations expected to be active in the first quarter of 2028.

At four hours of duration, once operational, Kilmarnock South will be the longest-duration asset in CIP’s growing UK storage portfolio.

The investment transaction was supported by Burges Salmon’s Corporate team, led by Camilla Usher-Clark with support from Briony Barber and Charlie Morgan. Following the acquisition, our Construction and Engineering team supported the procurement and negotiation of the construction package, led by Laura Sharples and Lloyd James, and aided by Sophie Smith, Ross Howells, Joanna Rogers, Tom Wild and Angelica Montagnini. Alec Whiter and Charlotte Robinson provided Offtake advice.
