Massive battery project rises on former coal mine in Scotland
Developers in South Lanarkshire are building one of Europe’s largest battery farms to store excess wind energy, aiming to stabilize the UK’s renewable power grid.
In short:
- The Coalburn site will store enough electricity to power 3 million homes and will be constructed in two phases.
- Excess power from wind farms will charge the batteries, which will discharge during high demand or when renewable generation is low.
- Copenhagen Infrastructure Partners is also developing a similar battery project in Fife, aiming for a total capacity of 1.5 gigawatts by 2027.
Key quote:
"By helping to supply reliable and secure power to our homes and businesses, well-located storage systems, such as batteries and pumped hydro storage, can move us closer to net zero and directly support the communities around them."
— John Swinney, First Minister of Scotland
Why this matters:
Renewable energy sources like wind are intermittent, making large-scale battery storage essential to balancing supply and demand. The shift from coal to battery storage underscores the broader transition to cleaner energy systems as the UK pushes for a net-zero carbon economy by 2050.
