Zenobē has secured £220 million in financing for its 400MW/800MWh battery energy storage system (BESS) in Eccles, Scotland, set to go live in early 2027. This marks one of Europe’s largest standalone battery storage financings and Zenobē’s biggest debt raise for a single asset. The funding was arranged by National Westminster Bank Plc and KKR Capital Markets Partners LLP.
With construction now underway, the Eccles project is the final phase of Zenobē’s £750 million investment in Scotland. It follows the recently operational 200MW/400MWh Blackhillock site, which will expand to 300MW/600MWh later this year, and the 300MW/600MWh Kilmarnock South project, set to launch in 2026. These facilities, alongside the 50MW/100MWh Wishaw battery, bring Zenobē’s Scottish storage portfolio to over 1GW/2GWh—more than twenty times its size when Wishaw began operations.
The Eccles battery will enhance grid stability, reduce wind curtailment costs, and support the UK’s transition to clean energy. Over 15 years, it is projected to save consumers £309 million and prevent 4.9 million tonnes of CO₂ emissions.
Zenobē’s Co-Founder Director, James Basden, emphasized the urgency of regulatory updates, stating that Britain’s energy market must adapt to ensure continued investment in battery storage. UK Secretary of State for Scotland, Ian Murray, hailed the project as a major step toward Scotland’s leadership in renewable energy.
KKR and Infracapital, key investors in Zenobē’s storage portfolio, reaffirmed their commitment to supporting grid-scale battery projects, recognizing their critical role in enabling the UK’s net-zero ambitions.
