Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what the total installed capacity is of combined-cycle gas turbine power stations in the UK; how much of that capacity is from plants commissioned in the last (a) five and (b) 20 years; and what the projected total capacity requirement is expected to be by 2029.

Data on combined-cycle gas turbine (CCGT) power stations are published in the Digest of UK Energy Statistics.

Modelling analysis from the National Energy System Operator, which covers Great Britain, suggests around 35GW of unabated gas capacity, which includes CCGTs as well as other types of gas generators, will need to be available by 2030 to maintain security of supply.
