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.
