Biomass Generation

Judith Cummins Excerpts

Monday 10th February 2025 Commons Chamber

[The Parliamentary Under-Secretary of State for Energy Security and Net Zero (Michael Shanks)]

With permission, Madam Deputy Speaker, I would like to make a statement about support for biomass electricity generation. My apologies to the House for it having to put up with even more of me.

In January 2024 the previous Government launched a consultation on supporting large-scale biomass generators when existing support ends in 2027. That consultation outlined their proposals to continue to support biomass as a

“valuable...form of dispatchable power”.

Since this Government came to office, we have carefully considered responses to that consultation and assessed the case for a new support mechanism. Biomass currently plays an important role in our energy system, but we are conscious of concerns about sustainability and the level of subsidy that biomass plants have received in the past. With that in mind, I want to report to the House on our conclusions about the role of Drax power station in Yorkshire in the years 2027 to 2031.

In coming to the view I will express today, we have taken advice from the National Energy System Operator on questions of security of supply, analysed the effect on consumers of support for biomass versus the alternatives, looked at issues around subsidy and sustainability in the existing arrangements, and considered longer term issues around decarbonisation.

First, on security of supply, we inherited a situation from the previous Government where there was no long-term planning for our energy system and its resilience. In the system we have inherited, large-scale biomass provides around 5% of our annual electricity generation, serving a specific role as a source of firm power. To meet our needs between 2027 and 2031, we could seek to replace Drax with new gas-fired power stations, but in the timescale we have there would be significant risks to relying on that approach. In that context, NESO has advised us that Drax plays an important role in delivering security of supply between 2027 and 2031.

Secondly, on price, we have undertaken comprehensive analysis of the costs of biomass against alternatives. Our central projections show that, on the right terms and in a much more limited role than today, biomass generation at Drax is the lowest cost option, including when compared with gas-fired power stations, for bill payers during this period.

Thirdly, we have looked at previous arrangements for subsidy and sustainability. This Government’s view is that they simply did not deliver a good enough deal for bill payers and enabled Drax to make unacceptably large profits. At the same time, they demanded levels of sustainability that are not now in line with the latest scientific evidence or global best practice, including supply chain emissions well above the European standard. We have concluded that if Drax is to continue to play a role in our power system, these arrangements must urgently be improved going forward.

Fourthly, we have looked at issues with decarbonisation. Our finding is that there is a potential role for bioenergy with carbon capture and storage—or power BECCS—but realistically this will take time to implement and therefore cannot form the primary basis of this decision. On the basis of that assessment, and given the circumstances that we inherited, the clear evidence is that Drax is important for delivering a secure, value-for-money power system in the period 2027-31. But we have also concluded that we cannot allow Drax to operate in the way in which it has before, or with the level of subsidy that it received in the past. On that basis, we have secured heads of terms that will form the basis of a very different agreement with Drax for support during the period 2027 to 2031.

Let me set out the terms of the agreement. First, it will ensure that Drax plays a much more limited role in the system, providing low-carbon dispatchable power only when it is really needed. Drax currently operates as a baseload plant, running around two thirds of the time. That means that it provides power even when other renewable sources are abundant. That must not continue. Under the new arrangement, Drax will be supported to operate only at a maximum load factor of just 27%. In other words, it will operate less than half as often as it does currently. That will be guaranteed by the design of the dispatchable contract for difference that we have agreed. When renewable power is abundant, Drax will not generate, and consumers will benefit from cheaper wind and solar instead.

Secondly, reflecting that change, the contract will deliver much better value for consumers. It will significantly reduce the amount paid in subsidies compared with the previous support mechanism. The new deal halves the subsidies for Drax—equivalent to a saving of nearly £6 per household per year. Furthermore, our analysis shows that the deal will save consumers £170 million in subsidy in each year of the agreement compared with the alternative of procuring gas in the capacity market. I can also inform the House that the deal limits the expected rate of return for Drax to a level below that of monopolies regulated by Ofgem, but while that is our central estimate, unlike the last Government we are not prepared to take the risk of prices soaring in response to volatile fossil fuel markets, so the agreement includes a built-in windfall mechanism, with rates of 30% and 60% that would claw back excess profits made by Drax, guaranteeing a much fairer deal for consumers than in the past.

Thirdly, we will introduce tough new measures on sustainability. We will increase the proportion of woody biomass that must come from sustainable sources from 70% to 100%. We will significantly cut the allowable supply chain emissions to a level in line with the much stricter regulations currently operating in the rest of Europe, and we will exclude material sourced from primary forests and old-growth forests from receiving support payments. There will be substantial penalties on Drax if those criteria are not met, and we will go further to ensure greater confidence that the standards will be met. I can inform the House that we will also appoint an independent sustainability adviser to work with my Department, the Low Carbon Contracts Company and Ofgem to ensure that our monitoring and enforcement measures are robust and keep pace with the science.

To be clear to the House, taken together the measures represent a profound shift from the past on both sustainability and value for money. In that context, this is the right deal for security of supply and price in the period 2027 to 2031, given the circumstances that we inherited from the previous Government. Nevertheless, we recognise the strength of concerns in this House and across the country about the use of unabated biomass. It is not a long-term solution. We are determined that the next time such decisions are made, the Government are not left in the circumstances we have been.

We will do the work that was not done by the previous Administration on strong and credible low-carbon alternatives, so that in four years’ time we will have proper options. To help that process, we are setting up an independent review to consider how options for greenhouse gas removal, including large-scale power BECCS and direct air carbon capture and storage, can assist the UK in meeting our net zero targets and ensure security of supply out to 2050. The review will take representations widely on the issues and report back in due course.

The steps that I have set out are about fulfilling our duty to ensure security of supply and the best deal for bill payers. We have come into office, faced up to the circumstances left by the previous Government, and delivered a step change in value for money and sustainability. The Government will do whatever it takes to deliver energy security, to protect bill payers now and into the future. I commend this statement to the House.

[Madam Deputy Speaker (Judith Cummins)]

I call the shadow Minister.

--- Later in debate ---

[Michael Shanks]

“Under new management,” indeed! The tough thing about being the acting shadow Secretary of State is that it is not, of course, his script that the hon. Gentleman is reading out.

This Government are fixing the mistakes left by the previous Government. I gently point out that eight previous Conservative Energy Ministers stood at this Dispatch Box and—deal after deal after deal—announced a worse deal than this for bill payers, energy security and sustainability. The hon. Gentleman seems to have forgotten that today. In fact, only a year ago—such is my love of his contributions in this House that I have read up on Hansard—he was saying that he had “absolute confidence” in the deal the previous Government made with Drax.

Let me outline why this deal is so different from those his party made in the past. The hon. Gentleman first asked about subsidy and mentioned a figure, which is what it will cost to deliver the necessary dispatchable power. He missed the fact that it is, of course, half of what was paid under the previous Government—nearly £1 billion a year—to Drax. We have halved that amount to lower bills for consumers.

Secondly, the hon. Gentleman spoke about sustainability. We agree on the importance of tightening up the sustainability, which is why we have moved from 70% to 100%. I would gently say, again, that he was quite happy to support public money going into unsustainable biomass year after year when he was in the Energy Department. We have said that we will not pay a penny of subsidy to Drax if there is unsustainable biomass in the mix.

Thirdly, what the previous Government did not do, of course, was any sort of deal to control the runaway excess profits—record profits—that Drax was able to obtain as part of its deal. We have put in place a mechanism to claw back that excess profit so that the people of this country do not pay over the odds for their energy.

Fourthly, I will address the important point about energy security. Year after year, the Conservatives exposed us to the lack of a plan for what the energy system would look like in the late 2020s and into the 2030s. This Government have had to take tough decisions quickly to secure that supply for the future, and that is what we have done. We have decided that running Drax when it was not necessary—when there were clean, cheaper alternatives in the system—will no longer happen. To the hon. Gentleman’s specific point on Drax running less, I say that limited generation times mean that it will run only when we need it for capacity to meet demand in the system. The alternative—he asked for the figure, which I set out in the statement—would be £170 million more every single year.

Finally, on the future of BECCS, we are open-minded at this point on the role it will play. However, I agree that it is important that we come to a decision on that soon. The review we have outlined is about bringing together all the various bits of science that we know are there in different reports and trying to work out a credible pathway for whether power BECCS will play a role in the system. We will make that decision as soon as possible.

I will finish by saying that this is an extremely different deal. It will deliver benefit for the hard-working people of this country, ensure that sustainability is at its heart and protect our energy security in the years ahead.

[Madam Deputy Speaker (Judith Cummins)]

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

[Bill Esterson (Sefton Central) (Lab)]

I congratulate my hon. Friend the Minister on his marathon stint and on the pragmatic and well-crafted analysis of how the Government’s energy policies will address the security of supply and provide the best deal for bill payers. This is in stark contrast to what the Conservatives did, and in particular to what my hon. Friend described as the terrible deal with Drax that they presided over while in office.

Today’s statement is a timely reminder of the challenges with Drax, not least given the news over the weekend of further misreporting of the burning of primary forest. NESO, in its future energy pathway, predicted a reduction in the use of biomass as part of the UK becoming more energy independent. Does the Minister, with his announcement, foresee that the cuts in subsidies and in the reliance on Drax will contribute to the Government’s clean power plan, to energy security and to reducing bills for all our constituents?

[Michael Shanks]

The Chair of the Select Committee is absolutely right about where Drax, and biomass generally, fits in our wider energy system. What we want to build at pace is a clean power system that takes us off the volatile fossil fuel markets. That is important, but there are short-term issues around ensuring we have the dispatchable power we need when we need it.

The Government have taken long-term decisions, for example in the first funding scheme for long-duration energy storage in 40 years. We hope to see modern new technologies of long-duration energy storage but also some classics from the history books, with pumped storage hydro playing a critical role in the system and delivering the dispatchable clean power we need. But there is a short-term question we need to answer that the previous Government did not have an answer for: how we get to 2031. We can build new gas units. Our analysis and the advice from NESO was that that was more likely to deliver energy security and in the end be cheaper for bill payers, who ultimately pay the bill. Our long-term ambition is to build towards that clean power system. This is an important step to get us the energy security that we need in the system.

[Madam Deputy Speaker (Judith Cummins)]

I call the Liberal Democrat spokesperson.

[Pippa Heylings (South Cambridgeshire) (LD)]

I thank the Minister for sharing his statement with us in advance.

Climate change and nature loss are undoubtedly the greatest twin threats we face. While pursuing the clean power by 2030 goal, the Government need to reconsider their decision to indeterminately extend the burning of biomass as part of the energy mix, despite overwhelming evidence that it is neither sustainable nor truly renewable, especially with the threat to virgin forests. The Minister says biomass is vital for energy security, supplying 5% of the UK’s electricity. However, he fails to mention that biomass emits 18% more carbon dioxide than coal and that it takes nearly a century for new trees to absorb those emissions. That is not energy security; it is a carbon ticking time bomb.

We are told by the Minister that NESO advised that Drax was a necessity between 2027 and 2031 to prevent supply risks. That is due to the reckless rowing back by the former Government, the absence of accelerated investment in renewables and the continued investment in Drax as part of their strategy, but what kind of future are we building if it depends on burning forests rather than investing in real renewable energy sources?

On costs, the Minister tells us that biomass at Drax is cheaper than gas-fired power, but we must not forget that past subsidies by the former Government allowed Drax to profit excessively at the expense of bill payers. Even today, despite halved subsidies, Drax’s shares have surged, suggesting that even this deal remains a good deal for Drax and potentially a bad one for taxpayers. We therefore call on the Government to release the 2022 KPMG report into Drax’s subsidy claims, which should have been released under the Conservative Government. Transparency is crucial and the public deserve to know if their money has been misused. I will end by asking: are we looking for home-grown clean energy—

[Madam Deputy Speaker]

I call the Minister.

[Michael Shanks]

I thank the hon. Lady for her questions. Her tone means that I will resist the urge to say that, although I made fun of the shadow Minister for the eight announcements, it was of course the current Liberal Democrat leader who agreed the first support deal for Drax. But we will move past that on to her important questions about security of supply.

The place we want to get to by the end of this period is one where we are not forced into making a decision like this again. It is really important to say that. We have a strong deal that protects bill payers, improves sustainability and delivers energy security, but we want to have options. The truth, as the hon. Lady rightly points out, is that we came into government without those options because of the decisions made by the Conservative party. That is a really important point.

As for the point about excess profits, there was previously no mechanism to claw them back. We made that a key part of the negotiation and we managed to get it into the deal. Even if our estimates are wrong—and the estimates, of course, mean that the profit will be below the level expected of the regulated companies by Ofgem—we can claw back the additional profit from Drax. That is important to the system.

Both the hon. Lady and the shadow Minister raised the question of KPMG’s reports. I know that my Department has seen them and engaged with them, and I know that Ofgem is still engaged in the audit process. I will take those questions away and see what can be done about sharing those reports.
