Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps she is taking to increase energy storage capacity for the purposes of (a) mitigating against price volatility and (b) providing resilience to the UK's energy supply.

In autumn, the Government will publish an update on the role that flexible supplies of gas - including gas storage - play in gas security. GB storage capacity is now c. 3.1bcm, having doubled in the past year.

The Government is facilitating the deployment of electricity storage at all scales through the joint Government and Ofgem Smart Systems and Flexibility Plan. Its approach centres on creating a best-in-class regulatory framework, ensuring that markets reflect the value of flexibility to the system, and investing in innovation.

The last Capacity Market auction secured 1.2 GW of de-rated new build battery storage for the 2026/27 delivery year.
