Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the role grid-scale energy storage will play in maintaining electricity supply when renewable generation is low.

Grid-scale storage helps to balance the electricity system at lower cost, maximise the output from intermittent low carbon generation, and provide electricity security.

The Clean Power 2030 Action Plan sets out ambitions for 23-27 GW of grid-scale batteries and 4-6GW of long duration electricity storage (LDES) by 2030. Batteries enable us to manage intraday variability, and LDES technologies enable us to cover multi‑hour to multi‑day energy deficits.
