My Lords, I rise to speak to Amendment 46 in the names of the noble Lords, Lord Ravensdale and Lord Krebs. It is interesting, as mentioned by the noble Lord, Hunt of Kings Heath, and the noble Baronesses, Lady Bennett of Manor Castle and Lady Pinnock, that we keep coming back to this issue of prioritisation, hierarchy and the role of regulators. I particularly note the comments of the noble Baroness, Lady Pinnock, that we need to start resolving this issue. I am sure that on this side of the House we shall come back to it as we progress through the Bill, but I want to focus on this amendment.

There is no doubt that we have to address the issue of low-carbon energy and low-carbon infrastructure. It will be essential to hitting our zero-carbon targets and addressing the challenges of climate change. Although we support the efforts to advance clean energy, we must also guard against an unbalanced approach, particularly one that risks compromising the reliability and resilience of our energy systems. Low-carbon generation should not be considered in isolation, as I believe the noble Lord mentioned, or privileged above all other forms of infrastructure. The grid as we know it is undergoing rapid change; the Government’s ambition to rebuild it around renewable sources within just five years is rooted in ideology. Solar and wind are by nature intermittent. They cannot provide the stable backbone that the grid requires.

The stability of our electricity system depends on what is known as inertia, the capacity to resist sudden fluctuations in frequency. This essential property is delivered by turbines in energy-dense technologies such as nuclear, hydro and gas-fired power stations. It is not delivered by wind or solar farms. Without sufficient inertia, we run the risk of system destabilisation, leading to the worst case of failures and blackouts. We need a serious, detailed plan to safeguard the resilience and sovereignty of the UK’s energy supply. That means ensuring a mix of technologies, including those that deliver system stability and resilience, as well as decarbonisation.

On the amendment, we have a number of questions which we hope noble Lords can address. First, it refers to “sustainable development”, a term that invites interpretation. In planning, there is already a well understood definition of sustainable development in relation to planning applications for housing and commercial development, but I do not believe that that is intended here. What precisely is meant here and how is it to be applied in practice? How do we avoid confusion with the existing interpretation of sustainable development?

Secondly, on the list of regulators, why were these specific bodies selected and by what criteria? We welcome collaboration, but it must be clear and consistent.

Finally, there is the matter of the Secretary of State’s powers to prescribe other relevant bodies by regulation. That is a significant authority, and I would be grateful for clarity on how it would be exercised and scrutinised. Although we support the spirit of this amendment, we urge caution and a desire to have a balanced approach.

Briefly, on Amendment 46A tabled by my noble friend Lady Coffey, she raises an important point, so we will listen carefully to the Minister’s reply. Ensuring that planning consent has considered environmental protections is of course vital and must not be overlooked.
