Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether her Department has targets for large-scale long-duration electricity storage deployment by (a) 2030 and (b) 2050.

We recognise the important contribution large-scale long duration electricity storage can make to delivering a secure, low-carbon energy system in a cost-effective manner. As set out in Powering Up Britain and British Energy Security Strategy, we plan to put in place an appropriate policy framework for enabling investment by the end of 2024.

We do not have specific capacity targets for long duration electricity storage in 2030 or 2050. Other technologies could play equivalent roles but through the development of the policy framework, we will establish an approach for determining access to revenue support.
