Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, a) what the UK's current gas storage capacity is as a proportion of average winter demand and b) how that compares with the capacity of other G7 countries.

The UK benefits from a secure, diverse energy system, drawing on a range of gas supplies. Gas storage provides additional flexibility at times of peak demand.

National Gas data indicates the UK has 1.7bcm of gas storage capacity, which is equivalent to around seven days of average winter demand.

The Department does not collect comparative G7 data.
