Greenfield has secured planning permission for the Earls Barton battery energy storage system in Northamptonshire.
The company said the project will support grid resilience, renewable integration and local electricity demand balancing while adding 99.9MW to its UK pipeline.
Greenfield added that it has already progressed 273MW of projects with partners as it expands its battery storage portfolio.
The Earls Barton BESS will connect to the distribution network to support local grid stability and more efficient management of electricity flows closer to demand.
The project is designed to deliver a biodiversity net gain of 2.18 habitat units, representing a 17.56% increase, alongside a 30.15% uplift in hedgerow units.
“Earls Barton is a strong example of the role battery storage must play in building a more resilient and flexible energy system. As renewable generation continues to scale, projects like this are essential to balancing the grid, reducing constraints, and ensuring reliable power where it is needed most,” said Hayden Kreetzer, principal town planner at Greenfield.
“As a fully Greenfield-led project, it also reflects our ability to originate and deliver critical infrastructure independently, supporting the UK’s transition to a secure, low-carbon energy future.”
