Zenobē has energised its 300MW/600MWh Kilmarnock South battery storage site in Scotland, one of the UK’s largest grid‑scale systems. The project reached commercial operation less than two years after financial close and follows the company’s 200MW Blackhillock system, which went live in March 2025.
The site boosts Zenobē’s operational UK capacity to 731MW, with a further 568MW/1230MWh under construction. It also forms part of the company’s £1 billion investment in Scottish battery storage and clean transport, bringing its Scottish portfolio to 1.3GW either operating or being built.
Kilmarnock South is only the second UK battery storage project capable of delivering Stability Services using grid‑forming inverters, following Blackhillock. Its location near major offshore wind developments will support a more resilient and efficient network as renewable generation grows.
Wärtsilä supplied its Quantum energy storage technology, Omexom delivered balance-of-plant works, and EDF Energy is acting as route-to-market provider, supported by Kraken’s control and dispatch platform.
Zenobē will continue local engagement through its Community Benefit Fund, administered by Foundation Scotland, supporting education and training initiatives.
Founder Director James Basden said: “Kilmarnock South is a landmark moment for Scotland – a world first, subsidy free battery that will reduce energy bills and strengthen Britain’s energy security. This battery will contribute towards ending the absurd waste of clean Scottish wind power.”
