Planning permission has been approved for the key substation site proposed for the Energy Superhub project in Oxford.
Flow storage company RedT said it enables plans to deploy a 50MW hybrid storage system, including 2MW/5MWh of its vanadium redox flow units, to progress.
Executive chairman Neil O’Brien said it would be the firm’s first grid-scale project in the UK.
The storage facility will be connected at transmission level at Cowley substation to underpin a network of EV chargers via a 10km private wire around the city.
The project will also install 300 heat pumps, which, along with the battery and EVs, will be smartly controlled to enable flexibility trading.
Pivot Power is raising investment for the project with government body UKRI putting up £10m. Habitat Energy will trade the flexibility, largely on the wholesale markets. Kensa Contracting will provide the ground source heat pumps.
The storage, private wire and EV chargers are slated to be in place by 2020, with the heat pumps installed by 2021, when the Renewable Heat Incentive closes.
