PARLIAMENTARY WRITTEN QUESTION
Energy: Storage (25 October 2024)

Question Asked

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential merits of battery energy storage systems.

Asked by:
Mr Luke Charters (Labour)

Answer

Battery energy storage systems (BESS) have a key role in cost-effectively decarbonising the power sector by 2030. They help to balance the electricity system at lower cost by maximising the output from intermittent low carbon generation (such as solar and wind) and minimising both network upgrades and the need for new infrastructure.

The Department’s analysis indicates that short-duration flexibility offered by technologies including battery storage, could support up to 24,000 jobs (1) and reduce energy system costs by up to £10bn per year by 2050 (2) through minimising the need for new peaking generation and network assets.
