Elements Green, a global developer of renewable energy projects, has completed the acquisition of the Newarthill Battery Energy Storage System project from Geocore (renewable energy development company), adding a 300MW transmission-connected asset near Motherwell, Scotland, to its growing UK energy storage portfolio.

Deal Details and Project Specifications

The Newarthill project carries a planned two-hour duration with the potential to expand to four hours. Planning consent for the project was granted on 4 February 2025, and a grid connection is available via an adjacent 275kV substation.

Elements Green has secured a grid offer from NESO (National Energy System Operator) as part of the ongoing grid reform process, with energization currently targeted for October 2029.

Bird & Bird and Brodies served as legal advisors to Elements Green on the transaction, while Savills Earth Capital Advisors acted as financial advisor to Geocore. Elements Green secured full ownership of the project.

Lloyd Garvie, Director of Geocore, noted that the development process spanned approximately four years and included navigating a complex period of grid queue reform.

"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," Garvie said.

"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." This transaction represents the second engagement between Elements Green and the Geocore team.

Strategic Grid Positioning

The Newarthill project is positioned within a constrained part of the UK transmission network, specifically around the B6 and B4 boundaries, where large-scale, transmission-connected flexibility assets are said to deliver substantial system-wide benefits.

According to Elements Green, Scotland's renewables-heavy generation mix, combined with persistent transmission constraints, creates significant opportunities for strategically located battery energy storage infrastructure.

Constraints across the network can limit exports to demand centers further south, leading to curtailment and redispatch costs. Elements Green states that large-scale battery projects such as Newarthill can help alleviate these constraints by absorbing excess renewable generation during congested periods and discharging power back to the network when demand increases, improving overall system resilience while reducing reliance on thermal peaking plants.

Rasmus Friis, CEO of Elements Green, described the location as occupying a strategically important grid node within Scotland. "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," Friis said.

"As the UK continues to decarbonize its electricity system, projects of this scale and positioning will become increasingly important."

Role in UK Energy Transition

Elements Green argues that battery storage is critical to balancing the UK's electricity network as more intermittent renewable generation comes online. The company states that projects such as Newarthill will help improve frequency response and system stability, unlock additional renewable capacity, reduce network congestion, and support decarbonization of the power system.

The acquisition is framed by Elements Green as part of a broader strategy to build a portfolio of large-scale, transmission-connected energy storage assets across key parts of the UK network.

The company says demand is growing for long-duration, transmission-connected storage assets capable of supporting renewable integration and managing increasing network volatility.

Expanding UK Portfolio

The Newarthill deal adds to a series of recent UK activities for Elements Green. The company also recently completed the acquisition of the 149MW Bolney Green Energy Hub, described as bolstering its UK storage portfolio. Separately, Elements Green completed the sale of its Italian solar portfolio, including the Brindisi solar park, to Bluefield in a transaction valued at approximately 30 million euros.

Elements Green has described its approach as continuing to expand its presence across strategically important grid locations in the UK and internationally.
