Recommendation 2

We are sceptical that plans for expanding nuclear, solar and wind power are credible. Government has set itself highly challenging electricity generating capacity ambitions for nuclear (24GW by 2050), solar (70GW by 2035) and offshore wind power (50GW by 2030). By comparison, the UK’s current operating capacity is less than a quarter of each of these ambitions. For example, its nuclear ambitions include a mix of large stations as well as so-called SMRs, a type of smaller reactor untested in the UK and not operating at scale anywhere in the world. The Department considers it worth pursuing this (and other nascent technologies) to ensure the UK has a range of options from which to select its ultimate power generating mix, and is not over- reliant on any single technology. The Department is creating Great British Nuclear to build capacity, expertise and a regulatory regime to expand its nuclear pipeline; however, in the last two decades, government has only agreed one project which has entered construction, at Hinkley Point C. The Department also says it is tracking offshore wind projects at various stages of development that could produce 80GW of electricity when operating. Should these projects generate this much electricity, the Department would exceed its ambition for offshore wind power; however, it acknowledges that not all these projects will succeed. Recommendation 2: The Department should provide annual updates to Parliament that demonstrate progress against milestones towards its objectives and identify how significant risks are being mitigated. 6 Decarbonising the power sector
