Technical FAQs 4

What are battery energy storage systems?

Battery energy storage systems offer power grids key opportunities for better flexibility, renewable energy integration, and reliable power supply by storing excess renewable energy during low demand times to release during peak demand enabling higher renewable energy penetration and supporting global decarbonisation.

What is battery energy storage system (BESS)?

As power systems increasingly integrate variable renewable energy sources such as solar and wind, the need for flexible and reliable power grids that can supply electricity at all times has become essential. Battery energy storage system (BESS) can address these supply-demand gaps by providing flexibility to balance supply and demand in real-time.

Why do we need energy storage?

Because power systems are balanced at the system level, no dedicated backup with energy storage is needed for any single technology. Storage is most economical when operated to maximise the economic benefit of an entire system. Don’t we need storage to reduce curtailment?

What is long duration energy storage (LDEs)?

Long duration energy storage (LDES), defined as storage of longer than 8 hours, is a vital part of the UK's future power system, helping to leverage the excess electricity produced today, store it, and deploy it as needed by the grid.
