Technology group Wärtsilä has signed a repeat order with EDF Renewables UK to deliver a 57MW/114MWh grid-scale energy storage system (ESS) in Bramford, a village in the east of England.

The order, which was booked in the first quarter of 2023 and is scheduled to be delivered in the first quarter of 2024, will be Wärtsilä’s sixth project with EDF and will also boost the company’s energy storage portfolio in the UK to 1GWh.

The storage facility will be connected to the transmission network and will help integrate renewable generation into the grid further supporting efforts to create a decarbonised power system by 2035.

Wärtsilä’s Bramford project will provide balance to the electricity system and also help electrify public transportation in the area. The project will be constructed near a planned solar farm, also being developed by EDF Renewables UK, which is currently awaiting a planning decision from local authorities.
