New battery project to store surplus wind power

The Government has welcomed a £232m investment in a major battery energy storage system to store surplus Scottish wind power.

Copenhagen Infrastructure Partners (CIP) has taken the financial investment decision for the 350MW Kilmarnock South project.

Construction is now underway with commercial operations expected 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.

Kilmarnock South is CIP's fourth investment in transmission-connected BESS projects in Scotland, joining Coalburn 1, which reached commercial operations in August 2026, Coalburn 2, and Devilla.

Michael Shanks, UK Energy Minister, said: “Together, these projects mean less homegrown power going to waste, greater energy security, and lower bills over the long term.”
