Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the impact of global gas turbine supply chain lead times on the delivery of dispatchable power capacity.

As set out in the Clean Power Action Plan, maintaining security of electricity supply in a Clean Power system will require continued reliance on the existing gas fleet as the main mature, reliable source of long-duration flexibility until low-carbon alternative dispatchable technologies are deployed at scale. Given the age of the fleet, a limited amount of new unabated gas capacity may be needed to replace retiring plants as part of a diverse and resilient energy mix.

The Department is engaging with industry to understand global supply chain constraints, including gas turbine availability, and is considering policy options to ensure market signals support timely investment in both refurbishment of existing plant and, where necessary, new build capacity.
