Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of how much curtailed wind energy could have instead been stored in batteries or other forms of energy storage.

The Government has not undertaken an assessment of how much curtailed wind energy could have instead been stored in batteries or other forms of energy storage. The Government has commissioned and published analysis by LCP Delta and Regen on the benefits of Long-Duration Electricity Storage (LDES), including reduced wind curtailment, which has informed policy to encourage storage deployment including the LDES Cap and Floor.
