Toshiba will provide the battery for the UK’s first 2MW scale lithium-titanate battery based Energy Storage System (ESS) to support grid management. Toshiba’s 1MWh SCiB battery will be installed in a primary substation in September.
Large-scale ESS are increasingly seen as a versatile solution in managing electricity supply. Installed in wind and photovoltaic generation systems, ESS can help to overcome intermittent output and frequency fluctuations, as well as performing peak power buffering, and when connected to the grid they can support grid stability and reinforcement.
This role in grid management will be investigated in the UK, in the Grid Connected Energy Storage Research Demonstrator project, led by the University of Sheffield, funded by the Engineering and Physical Sciences Research Council (EPSRC), with support from both industrial and academic partners.
The ESS will be connected to the 11kV grid at Western Power Distribution’s Willenhall primary substation, near Wolverhampton in the West Midlands. When the project starts operation in November this year, it will allow testing at realistic levels, and allow assessment of both the technical and economic potential of ESS in the grid.
Toshiba’s SCi is a lithium-titanate based secondary battery capable of over 10,000 charge-discharge cycles with and aclow risk of fire – a danger associated with other lithium-ion batteries.
