The technology group Wärtsilä has signed a contract with EDF Renewables UK and Ireland to deliver a new grid-scale energy storage facility in Sundon in Bedfordshire in UK. The 50 MW / 100 MWh project, which will form part of a new Energy Superhub in the region, will help to support the transition to a decarbonised electricity system and accelerate the UK’s net zero future. The order was included in Wärtsilä’s order book in Q4 2022, and construction is expected to start in spring 2023. The new 50 MW / 100 MWh lithium-ion storage facility in Sundon can store enough electricity to power 100,000 homes for two hours1, and it will support electric vehicle charging and the electrification of public transport. The project will enable increased renewable energy integration and intermittency management, in addition to strengthening the resiliency of the electricity system, automatically charging and discharging to balance supply and demand. Wärtsilä has provided its propriety GridSolv Quantum system and GEMS Digital Energy Platform, in addition to the power conversion system and commissioning for the project. GEMS provides the data and insights to instruct trading parties and performance for comprehensive asset management. The energy storage technology will enable balancing services for the UK grid, including electricity market trading and frequency response, with the capability to support local consumers such as EV charging stations during grid outages.
