Electricity Capacity Mechanism (Amendment) Regulations 2024

We keep the capacity market mechanism itself under constant review and consult regularly on amendments and incremental reforms. In late 2024 we consulted on a number of changes to the capacity market to ensure security of supply and enable flexible capacity to decarbonise. We hope this will ensure that supply can meet demand as we transition to net zero.

As for the comment about the mix of technologies going forward, the report by NESO and my department’s clean power action plan set out our view of the technologies by around 2030. We will rely on unabated gas as the main mature, reliable technology capable of filling that role at the moment. We expect that the amount of unabated gas we need will reduce as we deploy more low-carbon technologies. Our aim is to move gas into a reserve role, used primarily to ensure security of supply.

The noble Earl also mentioned tidal and other technologies, and we remain open to those possibilities. He may know that I am meeting the noble Lord, Lord Alton—tomorrow, I think—to discuss tidal, so we are not ruling out the use of those technologies. I am grateful to noble Lords.

Furthermore, following the UK’s withdrawal from the European Union, the domestic subsidy control regime was introduced. The subsidy control regime does not require subsidy schemes to be granted an approval or limited for a specified period. Therefore, the approval requirement in the assimilated electricity regulation does not reflect our post-EU exit arrangements. Of course, it is important that we keep the capacity market under review and there are multiple controls set out in domestic legislation, all of which will be retained. This includes a statutory requirement for my department to review the capacity market regulations every five years, which provides an opportunity to review the need for the scheme. Ofgem also undertakes an independent five-yearly review of the capacity market rules. Furthermore, the Secretary of State can decide not to hold a capacity market auction. These embedded controls all remain as part of the wider domestic capacity market legislative framework.

In conclusion, this draft instrument revokes and alters certain provisions related to the capacity mechanism in the assimilated electricity regulation. This includes a requirement for an approval lasting no more than 10 years, as well as references to capacity mechanisms being of a temporary nature. These changes are being made to ensure that our domestic legislative arrangements reflect the continuation of the capacity market, which is Great Britain’s main mechanism for ensuring electricity security of supply. I beg to move.

As we seek to reach net-zero carbon generation by 2030 and beyond, the Government have a continued dependency on unabated gas and propose that carbon capture and storage should be used as a key part of our energy mix. Indeed, the clean power 2030 plan has around 35 gigawatts of unabated gas on standby for security of supply, and this requirement for gas capacity will remain throughout the early 2030s until more low-carbon dispatchable power comes on board to replace it. Although required, back-up reserve gas generation that is used intermittently and only when necessary is also very expensive, understandably. The Government have agreed to invest some £22 billion over the next 25 years in carbon capture technology to help make sure that we can have this unabated gas without adding to our greenhouse gas emissions.

The week before last there was a debate in the Chamber on the Science and Technology Committee’s report on long-term energy storage. We have also had a couple of Questions about the Russian shadow fleet and the attack on Baltic power cables. Of course, renewable energy is not always reliable, and everybody knows that it needs to be backed up by a wide variety of other sources to help ensure the security of supply. On that basis, can I ask the Minister about the Government’s proposed energy mix going forward to net zero and beyond? I am a little concerned that we continue to have this requirement: it is basically solar, wind and dispatchable gas backed by CCS and nuclear. Will the Minister say a word about how the Government will keep this mix under continuous review? I encourage them to invest in alternative renewable technologies, such as wave, tidal and geothermal, that are able to provide the dispatchable power that we need. What is the Government’s thinking on that?

We must also ensure that all the wind energy we generate is available and can be used. As I said, there is also a need to radically increase our medium and long-term energy storage, which is available to help us get through periods when other sources of renewable energy are not on tap. I hope that the reforms to the capacity market already announced will help make that happen. More must also be done to reduce demand; as the Government know, the best energy is the energy we never use.

Turning to this SI, I note that, as the Explanatory Memorandum says,

“there is a requirement to review the Electricity Capacity Regulations … at least every five years to determine whether they are meeting their objectives and remain fit for purpose”,

and I note that the Minister said the Government will continue to keep the controls in place. As we are going through such a rapid period of change, we welcome the fact that the Government have brought forward the plan to decarbonise our power generation by five years, but what consideration have they given to the need to review these mechanisms more than every five years? What might trigger that? What is the Government’s thinking on those matters?
