Europe’s Largest Battery Storage Facility Launches in Scotland

The Blackhillock site delivers 200MW of capacity, with plans to expand to 300MW by 2026, supporting renewable energy integration and grid stability.

Zenobē's Blackhillock battery site in northern Scotland, now operational, is the largest battery storage facility in Europe with a current capacity of 200MW/400MWh.
Once fully expanded to 300MW/600MWh in 2026, the facility will be capable of powering over 3.1 million homes for two hours, exceeding the total number of households in Scotland.
The project addresses grid congestion from major offshore wind farms and provides stability services to the UK's National Energy System Operator, reducing reliance on fossil fuels.
Cutting-edge technology from Wärtsilä, including the Quantum energy storage system and GEMS Digital Energy Platform, ensures efficient energy storage and grid integration.
The facility is expected to save consumers £172 million over 15 years and prevent 2.6 million tonnes of CO₂ emissions by optimizing renewable energy use.
