UK’s largest flow battery system connected to grid
Date: Nov 14, 2017
The UK’s largest flow battery system has been connected up to the power grid.
The vanadium redox flow technology will initially be used to store excess power from solar generation at the Olde House farm and holiday retreat in Cornwall until it is needed on site.
The containerised system has a storage capacity of 1MWh, a maximum output of 90kW and a lifespan of at least 25 years.
The supplier, RedT, says it will enable the site owner to cut imports from the power grid by up to 50 per cent during peak hours. It will also participate in the capacity market and be used to provide frequency response, short term operating reserve and demand turn-up services.
The installation has been partly funded by the Department for Business, Energy and Industrial Strategy as well as Centrica, which will eventually take over the operation of the system from RedT. It is the first energy storage system to be signed up to Centrica’s £19 million local energy market (LEM) trial in Cornwall.
