The technology group Wärtsilä has supplied a 50 MW / 50 MWh lithium-ion battery to Pivot Power, part of EDF Renewables, who have developed a cutting-edge hybrid battery site in Oxford in UK. The hybrid battery system, which was officially launched today at the opening of Energy Superhub Oxford, will play an essential role in the UK’s shift to renewables.The hybrid battery combines Wärtsilä’s 50 MW / 50 MWh lithium-ion battery with Invinity’s 2 MW / 5 MWh vanadium-flow battery. The system will be controlled and dispatched by Wärtsilä’s GEMS Digital Energy Platform and optimised by Habitat’s AI-enabled battery trading system, with the project being owned and developed by Pivot Power.The hybrid battery is the first of its kind in the UK, designed to fulfil multiple energy storage needs and support the ramp-up of renewable energy required to reach the UK’s targets of 50 GW of offshore wind and 70 GW of solar capacity by the 2030s. It is also the first in the UK to be directly connected to the National Grid’s high-voltage transmission network at the Cowley substation on the outskirts of Oxford., with the UK’s largest flow battery providing a unique overdrive function that allows it to be operated at higher power levels for sustained periods of time.The site forms one part of the 41 million GBP Energy Superhub Oxford project. ESO integrates energy storage, electric vehicle charging, low carbon heating, and smart energy management technologies to decarbonise Oxford by 2040 and create a blueprint for other towns and cities to achieve net zero. The hybrid battery system is a short distance from the Redbridge Park and Ride, where the project’s EV charging hub is located, and can provide backup power for the EV charging infrastructure.Wärtsilä has provided both the lithium-ion battery and GEMS Digital Energy Platform for the project. The GEMS system has been optimised for hybrid system control, managing significant complexities across battery chemistries and asset integration. GEMS supports the shift to small-scale decentralised generation by enabling the delivery of different services, from frequency regulation to enhanced grid resilience, as well as providing critical feedback to stakeholders across asset owner, operation, and trading value chains.
