Elements Green has acquired the 300MW Newarthill battery energy storage system project in Scotland from Geocore.
The company said the transmission-connected project near Motherwell has a planned two-hour duration with potential expansion to four hours and is targeted for energisation in October 2029.
Elements Green added that planning consent for the project was granted on 4 February 2025 and that a grid offer has been secured from NESO through the grid reform process.
The developer said the acquisition strengthens its UK battery energy storage pipeline as demand grows for long-duration storage assets supporting renewable integration and network flexibility.
The Newarthill project is located near the B6 and B4 grid boundaries in a constrained area of the UK transmission network.
“This acquisition represents another important step in Elements Green’s strategy to build a portfolio of large-scale, transmission connected energy storage assets across key parts of the UK network,” said Rasmus Friis, chief executive of Elements Green.
“Newarthill is a high-quality project located at a strategically important grid node within Scotland, where significant renewable generation coincides with growing system constraints and strong demand for network flexibility.”
“After spending the past four years developing the Newarthill BESS project and navigating a complex period of grid queue reform it is hugely rewarding to have secured the right long term owner and funder,” said Lloyd Garvie, director of Geocore.
“Newarthill sits at a critical grid node, where high urban demand coincides with significant renewable generation, making it an ideal asset for Elements Green as it deepens its presence in the UK BESS market.”
