What are electricity system batteries?
Lithium-ion (Li-ion) batteries are emerging as one of the fastest growing battery technologies for grid applications to improve both connectivity and continuity. They have significantly benefited from R&D development aimed at commercialising their use in transport applications.
The cost of battery technology has fallen rapidly over recent years. They are presently deployed globally from small scale distributed systems (1-10 kW) to larger (1-50 MW) fast responding systems for frequency services and energy time shifting. Currently some 200MW4 of grid scale batteries are deployed in the UK.
