Scotland can be a wild and windy place, which is good for wind turbines. Blackhillock substation near Keith in the northeast of that country was already the size of 24 football pitches. But by 2023, Scottish Southern Electricity Network had started adding a 300 MW / 600 MWh grid battery to the facility. This has now become the biggest battery farm in Europe.
Europe’s Biggest Battery Farm in Scotland
The first phase of the Scottish big battery project, can deliver up to 200 MW of electricity, and store as much as 400 MWh. Input power comes from onshore and offshore wind turbines, already generating.
The Register website confirms this capacity will increase by 2026, to 300MW / 600MWh. This could enable the biggest battery farm in Europe to power the whole of Scotland for 2 hours if necessary, all things being equal.
Local operator Zenobē sourced the farm batteries and digital platform, from Finnish supplier Wärtsilä. The batteries are therefore likely to use lithium-ion chemistry, although we understand Zenobē also supplies lithium iron phosphate, nickel manganese cobalt, and nickel metal hydride batteries.
More About the Project at Blackhillock, Scotland
We visited the Zenobē website to see what we could learn, and to source our preview image. We discovered that the first 200 MW phase had entered commercial operation on March 3, 2025, just a few days earlier.
The Blackhillock site between the Scottish cities of Inverness and Aberdeen, seems a logical choice, given grid congestion involving three smaller offshore wind farms. However, and this is the exciting part, Blackhillock will also be the first battery farm anywhere to provide stability services to a national operator.
Zenobē expects the project to save consumers more than £170 million over the next 15 years. It will also prevent around 2.6 million tonnes of CO₂ from entering the atmosphere during that time. This sounds like a major milestone to us, on our journey to universal renewable energy.
