To ask the Secretary of State for Energy Security and Net Zero, what recent estimate his Department has made of the level of electricity generating capacity that will be required in each year between 2023 and 2050; what the minimum generating margin will be in each of those years; and if he will make a statement.

Net Zero consistent scenarios for the power sector are published as Annex O of the Energy and Emission Projections.[1] In line with National Grid targets, these scenarios are configured to ensure a minimum lost load of 3 hours in any given year.
