A £41m energy hub in Oxford is taking shape with the largest hybrid battery system in the UK (see video below).
The Energy Superhub Oxford (ESO) project will use a hybrid 50MW lithium ion energy storage system with a 2MW vanadium flow battery to showcase the latest technologies for electric vehicle charging, energy storage systems, and low carbon heating, as well as smart energy management.
Pivot Power will create a new connection to the transmission network servicing the largest hybrid battery ever deployed and bringing power to a 10 km network of charging stations that will kickstart an electric vehicle revolution across the city. Pivot Power’s private-wire network across south Oxford will have enough power to charge hundreds of vehicles at the same time.
Approximately 100 ultra-rapid and fast chargers will be installed initially at a public charging station on the A34 and at the Council’s main vehicle depots. The network will also run past the city’s two main bus depots, providing the opportunity for their fleets to go electric. The Pivot Power lithium-ion battery and the 2MW vanadium redox flow battery will share the grid connection with the private wire network, which is a key energy management challenge.
Habitat Energy, an Oxford-based firm, will provide the intelligence to optimise the trading of the battery storage in the power markets, as well as the timing of the EV charging and heat pump activation to maximise value to the end consumer and benefit to the grid.
The machine learning technology will optimise the system and help balance the grid by enabling greater use of clean, renewable energy sources, while carrying out trading on the day ahead, intraday and balancing mechanism markets. It will also predict overall demand on the private wire network to support the management of future fleet charging.
Oxford Council is also expanding its fleet of electric vehicles and local taxis that will use the charging network.
