Nuclear Power: Emissions

Debate between Lord Ravensdale and Lord Duncan of Springbank

Tuesday 14th January 2020 Lords Chamber

[Lord Ravensdale (CB)]

I beg leave to ask the Question standing in my name on the Order Paper. In so doing, I declare my interest as an engineer in the energy industry, as set out in the register.

[The Parliamentary Under-Secretary of State, Department for Business, Energy and Industrial Strategy and Northern Ireland Office (Lord Duncan of Springbank) (Con)]

My Lords, a substantial increase in low-carbon generation will be needed to reduce our emissions to net zero by 2050. Nuclear power currently provides a fifth of our generation and will have an important role in securing a low-cost, stable, reliable low-carbon system by 2050. The Government will publish an energy White Paper in 2020, which will provide further detail of the necessary transformation of our energy system.

[Lord Ravensdale]

My Lords, I thank the Minister for his response. Our current nuclear fleet is approaching the end of its working life and only a single new station is being built. We need much more than that to provide additional zero-carbon firm power and reduce the risk of not meeting net zero by 2050. Does the Minister agree that a key means of doing this at least cost is to focus on replication: building a number of the same design to learn lessons and gain efficiencies, rather than using a wide range of designs, as per the previous strategy? Can he confirm that the Government are prioritising a decision on the financing of new nuclear to enable the industry to move forward?

[Lord Duncan of Springbank]

The simple answer to that question is yes, but more details are required. The first thing to remember is that by 2030 all but one nuclear power station will be closed.

The noble Lord’s second point is correct: we do need replication on a common theme to help us, but there are other factors too, not least of which is experienced management in the construction industry and sometimes constructing nuclear reactors in greater numbers on the same site. Each of these can make a significant difference, and in order for us to increase capacity we need, in the energy White Paper, to give serious consideration to them, at which point the decision-making will be made clear.
