Elements Green has completed the acquisition of the Newarthill Battery Energy Storage System (BESS) project from Geocore, marking a further expansion of its UK energy storage portfolio.
The Newarthill project, located near Motherwell, Scotland, is a 300MW BESS with a planned two-hour duration and the potential to expand to four hours. This transmission-connected asset will play a key role in supporting the UK’s energy transition.
Planning consent for the project was granted on 4 February 2025. A connection is available via an adjacent 275kV substation, with a grid offer secured from NESO as part of the ongoing grid reform process, supporting progression towards delivery. Energisation is currently targeted for October 2029.
Bird & Bird and Brodies acted as legal advisors to Elements Green. Savills Earth Capital Advisors acted as financial advisor to Geocore on the transaction.
The acquisition further strengthens Elements Green’s UK BESS pipeline as demand grows for long-duration, transmission connected storage assets capable of supporting renewable integration and managing increasing network volatility.
The project is positioned within a constrained part of the UK transmission network and is expected to play an important role in enabling higher penetration of renewable energy, supporting system stability and reducing reliance on fossil fuel backup generation.
The Newarthill project occupies a strategically important position around the B6 and B4 boundaries, where large-scale, transmission connected flexibility assets can deliver substantial system-wide benefits.
Elements Green secured full ownership, as the company continues to expand its presence across strategically important grid locations in the UK and internationally.
Scotland’s renewables-heavy generation mix, combined with persistent transmission constraints, creates significant opportunities for strategically located BESS infrastructure. Constraints across the network can limit exports to demand centres further south, leading to curtailment and redispatch costs.
“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. As the UK continues to decarbonise its electricity system, projects of this scale and positioning will become increasingly important.
“We would like to thank everyone involved in the transaction for their collaboration and hard work throughout the process,” comments Rasmus Friis, CEO of Elements Green.
