Government Statement

Sixteen years ago, as Energy Secretary, Ed Miliband identified potential sites for new nuclear. Today he is announcing £14.2 billion of public funding to build Sizewell C, the first Government-funded and owned nuclear power station in Britain since the 1980s, alongside a strategic partnership with France. The project will provide clean energy for 6 million homes for 60 years, support 10,000 jobs at peak construction and create 1,500 apprenticeships. Additionally, Rolls-Royce SMR has been selected as the preferred bidder to develop the UK’s first small modular reactors (SMRs) with more than £2.5 billion in funding over the period, aiming to deliver one of Europe's first SMR fleets. The Government also pledged to invest more than £2.5 billion in nuclear fusion, including in the STEP programme for a new prototype fusion plant at West Burton. Finally, steps are being taken to provide a route for private sector-led advanced nuclear projects and Great British Energy Nuclear will assess proposals with potential investment opportunities from the National Wealth Fund.

Shadow Comment

Nick Timothy

While welcoming decisions backed by investment that increase Britain’s nuclear capacity, Nick Timothy questions the scale of the announced investment compared to the £230 billion cost. He highlights that despite Labour coming to power in 1997 stating no economic case for new nuclear power stations, the current statement is a downgrade on what was planned previously. The previous Government committed to building more reactors and had plans for Wylfa, which are not mentioned in today's announcements. Timothy calls for a third gigawatt-scale reactor at Wylfa and asks if Ed Miliband can commit to this and recommit to the Conservative policy of 24 GW of nuclear power by 2050.
