Technology group Wärtsilä Energy has signed an additional contract with EDF Renewables UK for a 50MW/100MWh lithium-ion energy storage facility in Sundon, Bedfordshire in southern England.

The project – due to begin construction in spring 2023 – will increase intermittency management and renewable energy integration, as well as strengthening the resilience of the electric system, and balancing supply and demand by charging and discharging automatically.

The Sundon facility will also support electric vehicle (EV) charging and the electrification of public transport.

The contract includes Wärtsilä’s GridSoly Quantum system and GEMS Digital Energy Platform. The GEMS technology delivers data and insights for trading parties and performance for comprehensive asset management.
