Recommendation 4

We reiterate the calls of both the Climate Change Committee and National Audit Office for the Government to publish a comprehensive, long-term delivery plan for a decarbonised power system by 2035. The creation of a new Department for Energy Security and Net Zero should provide the impetus and Ministerial capacity to do this. This plan should recognise the time needed to decarbonise the different aspects of the electricity system as well as the sequencing involved. We recommend that this delivery plan sets out clear roadmaps and milestones as well as contingency plans for key risks and uncertainties. It should also focus on whole system costs. We ask the Government to publish this delivery plan no later than by the end of 2023.
