Briefing: Electrical energy storage options

Traditional power systems were based on large centralised generation supplying electricity to consumers through transmission and distribution networks, but a high proportion of renewable generation is now connected at the distribution level, which together with substantially different consumer demand profiles is changing the way that power systems are designed and operated. Electrical energy storage technologies, including battery energy storage, can complement existing generation types as well as new forms of renewable generation, as well as supporting the development of the network infrastructure.
