“We need to use all available low-carbon sources… New nuclear is right for energy security and climate change, and it will be good for jobs too”. —[ Official Report , 9 November 2009; Vol. 499, c. 31.]

That was true back then, and it is even more true today. Russia’s invasion of Ukraine and the cost of living crisis that followed showed how vulnerable we are as a country because of our dependence on fossil fuels, at the whim of markets controlled by petrostates and dictators. The imperative of energy security and the demands of the climate crisis mean that we must shift as fast as possible to clean, home-grown power. The demand for that power, as we shift away from gas, is expected to at least double by 2050, so we need all the low-carbon sources possible to meet the demands we face.

The advice from experts, including the Climate Change Committee, is clear: we need new nuclear to meet our climate obligations. This Government support new nuclear because of our belief that the climate crisis is the greatest long-term threat facing our country and our world, not in spite of it; because of the imperative of energy security; and because of the good, skilled jobs that nuclear provides. In Britain today, there are too few industries that offer the secure, well-paid jobs with strong trade unions that the British people desire and deserve. Time and again, I have heard from people up and down the country about the importance of nuclear jobs to their communities. For all these reasons, the Government are taking decisive steps today to usher in a new golden age of nuclear for Britain.

Taken together, the steps that I have announced today will kick off the biggest nuclear building programme that Britain has seen in half a century, doubling down on our nuclear strength to take the latest step forward in our mission to make Britain a clean energy superpower. When people ask what clean energy and net zero means for our country, this is what it is all about. For too long, our country has not made the crucial investments in energy or infrastructure that we need. The British people have paid the price for this short-sighted failure to invest—in lower living standards, insecurity and declining public services. This week’s announcements signal a decisive change in approach—to invest in the future and make the right choice for energy security, the right choice for jobs, the right choice for climate, our children and grandchildren, the right choice for Britain, and the right choice of investment over decline. I commend this statement to the House.

12:46 Nick Timothy (Conservative)

The Conservative party is a pro-nuclear party and we welcome any decisions, backed by investment, that increase Britain’s nuclear capacity, because we cannot deliver cheap, reliable and secure energy without it. Although the investment announced today by the Secretary of State is significant, it is a fraction of the £230 billion cost, which will ultimately be borne by consumers, of his plan to decarbonise the grid. Unlike the intermittent technologies backed at such cost by the Secretary of State, nuclear provides reliable baseload power. It generates inertia to stabilise our grid. Nuclear power plants require substantially less new grid infrastructure compared with dispersed generation from wind and solar. It is to the shame of successive Governments over many years that Britain relinquished its status as a world leader in civil nuclear technologies. In 1965, we had more nuclear reactors than the United States, the USSR and the rest of the world put together. Between 1956 and 1966, we built 10 nuclear power stations, but we gave all that up. The contribution of nuclear to our power generation peaked in 1994 and has fallen consistently since then.

Canada has approved a plan for four SMRs by 2029. As things stand, Britain will not have SMRs connected to the grid until the 2030s. The contrast between this caution on nuclear and the Government’s rush to decarbonise the entire grid in just five years, while betting the house on unreliable and intermittent renewable technologies and shutting down British oil and gas in the North sea, could not be clearer. We need the Energy Secretary to focus on the positive, not to stake our country’s future and people’s bills on ideology.

I call the Chair of the Energy Security and Net Zero Committee.

12:56 Pippa Heylings (Liberal Democrat)

The Liberal Democrats believe that the best way to cut bills, create good jobs and boost energy security is to invest in home-grown renewables such as solar, wind, tidal and geothermal, and to upgrade our national grid to deliver that clean power. We look forward to seeing more detail on the long-overdue reform of the outdated first come, first served grid connection system, which is holding back renewable energy projects and could even delay the roll-out of new SMRs. Today’s announcement is a step in the right direction, but the real test is in the delivery of cheaper bills, stronger energy security and a modern energy grid fit for the future.

13:00 Ed Miliband (Labour)

I thank the hon. Member for part of what he said, if not most of it. We have a fundamental disagreement. Solar and wind offer cheap power for our country—why would we possibly say no to that? The biggest threat to the countryside is the climate crisis, and solar and wind alongside nuclear are the way to tackle it.

Andy McDonald (Labour)

Happy birthday, Mr Speaker. I welcome the Government’s commitment to securing our future energy supply and, by doing so, taking control of our energy, protecting family finances and tackling the climate crisis. In addition, I am keen to learn about the Department’s assessment of new technological developments to reduce energy waste, in particular through developing underground thermal energy storage solutions. I am aware of organisations in that sector that are keen to share opportunities with the Government, so what is the Secretary of State’s assessment of the role of thermal storage solutions in reducing energy loss, avoiding curtailment fees and maximising the benefit from energy generated?

Ed Miliband (Labour)

The right hon. Gentleman asks perfectly legitimate questions. I am glad to say that decommissioning is in at the beginning of the financing model, as part of the overall costs. We will lay out total costs when the final investment decision is made. Similarly, on the regulated asset base costs—I know that he genuinely cares about the climate crisis—all the evidence we have shows that this is our lowest-cost alternative, compared with other low-carbon technologies, so it is a crucial part of the energy mix.

Luke Murphy (Labour)

I refer the House to my entry in the Register of Members’ Financial Interests. I welcome the investment in our energy security and jobs. I know from my visit to Sizewell with the Energy Security and Net Zero Committee that jobs in the nuclear industry are good, well paid and highly skilled. Does the Secretary of State agree that that is in part thanks to the strong relationship between business, trade unions and the Government in that sector, and that there is much to be learned from that relationship in other parts of the energy sector and beyond?
