Zenobē has begun commercial operations at its 300MW/600MWh Kilmarnock South battery energy storage system in Scotland.
The site has gone live in just under two years after financial close and follows the company’s 200MW Blackhillock BESS entering operation in March 2025, said the developer.
Kilmarnock South forms part of Zenobē’s £1bn investment into battery storage and clean transportation in Scotland, according to the company.
The launch takes its operational UK capacity to 731MW with a further 568MW/1230MWh under construction.
The project, located near several offshore windfarms, will also provide Stability Services using grid-forming inverters and will be only the second BESS in the UK to deliver this capability after Blackhillock.
Zenobē worked with Wärtsilä supplying its Quantum technology, Omexom providing Balance of Plant works and EDF Energy acting as route to market, while Kraken’s platform will support energy trading.
The company will continue to work with the local community through its Community Benefit Fund administered by Foundation Scotland.
Zenobē 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.”
“We’re incredibly proud of what the Zenobë team and our supply partners have achieved. Reducing bills for consumers nationwide by harnessing more renewable power is a key criteria for Zenobë as we build out our battery fleet in the UK.”
