Renewables Obligation Certificate Scheme

Debate between Nick Timothy and Kerry McCarthy

Wednesday 5th March 2025 Westminster Hall

[Kerry McCarthy]

My hon. Friend makes a valid point. I wonder whether the Opposition spokesperson has spoken to businesses on this matter because, in all my conversations with businesses, both in opposition and now in government, it is clear that they want certainty. They need a stable investment environment if they are to make long-term decisions. They cannot invest in renewable energy, in industrial decarbonisation or in the economic growth this country needs without certainty. We know that one reason why we are in the economic situation we are is the lack of stability and the economic chaos at times under the previous Administration, particularly under the predecessor of my hon. Friend the Member for South West Norfolk. Therefore, certainty is what we need to have. Business is crying out for that.

In places such as Grimsby, it is particularly important to have a place-based solution to the current situation, showing what the energy transition would look like in such places. I urge the hon. Member for West Suffolk to take a bit of a tour, to talk to businesses and people who are trying to get much-needed investment into places such as Grimsby, and to see—I am not quite sure what his proposals are—what he can say to them on how to get long-term investment.

[Nick Timothy]

Of course we talk to business all the time. I talk to businesses in my constituency and we have been talking to businesses and organisations representing the more energy-intensive manufacturing businesses in this country. They are clear that energy costs have been too high, partly because of issues such as high carbon prices. They are very concerned about the prospect of the carbon price rising under this Government. The hon. Lady talked about global fossil fuel markets—I have heard the Energy Secretary say that a lot when he has referred to global gas markets. There is no single global gas market in the way he describes. Prices for fossil fuels are so much higher in Europe than America, which is much more dependent on fossil fuels than we are, because of policy choices. Therefore, can she guarantee that we will have a lower carbon price than the rest of Europe by the end of this Parliament?

[Kerry McCarthy]

I understand that the hon. Member asked the Secretary of State that question at the last DESNZ orals and I think he also raised it when we were opposite each other in a statutory instrument Committee. I refer him to the answers that were given then. I think we should get on—I am going to try to talk about the renewables obligation for a while and not be distracted.

The scheme played a fundamental role, as already noted, in getting the UK to where we are now on renewable energy generation. Combined, the UK-wide RO schemes support nearly 32% of the UK’s electricity supply, providing millions of UK households and businesses with a secure supply of clean energy. The scheme is now closed to new capacity, for reasons I will come on to.

Thetford power station, in the constituency of my hon. Friend the Member for South West Norfolk, has been accredited since the first day of the RO, back in April 2002, so it has so far received Government support for nearly 23 years. Over that time, it has generated more than 5.8 TWh of low-carbon baseload generation. That has been a valuable contribution to our transition to net zero. It has also increased our security of supply by generating home-grown energy. As he said, the station has provided 100 jobs in his constituency and co-benefits in handling poultry litter.

The station has another two years of support before its time under the RO ends, in March 2027. We are aware of the concerns about the future of the station once that support ends and my hon. Friend has done an excellent job in outlining those concerns today. My officials have repeatedly engaged both with the owners of the Thetford plant, Melton Renewable Energy, and with DEFRA officials to discuss those concerns.

To explain the overall context, as I have said, the RO has done sterling service in bringing forward the successful large-scale renewable energy sector that we see in the UK today. That has paved the way, as my hon. Friend the Member for Great Grimsby and Cleethorpes (Melanie Onn) said, for the cost reductions that we have seen over the last few years under the contracts for difference scheme, but its time has passed. The energy landscape has evolved since the scheme was launched in 2002 and it no longer provides the market incentives or the value for money that the transition to clean power requires.

The RO was designed to support renewable energy-generating stations during the early stages of development and generation, and to allow the recovery of high capital costs. For that reason, RO support is often significantly higher than that provided under successor policies such as contracts for difference. We must always bear in mind that consumers pay for the scheme through their electricity bills, and delivering value for money for them is essential. For that reason, we do not plan to extend RO support.

As I said, support under the RO for the early adopters, such as Thetford power station, lasts for 25 years. Stations accredited later in the RO’s life receive support for up to 20 years. All support will end in March 2027, when the last assets fall off the scheme and the RO finally closes, so Thetford—as I am very aware—has two years to run. The limits on the length of support were imposed to balance the need to provide investors with important long-term certainty—for 25 and then for 20 years—with the impact on consumers.

Although we do not consider extending the RO to be a viable option, I assure my hon. Friends that I understand their concerns. In some cases, generating stations may be able to continue generating electricity on merchant terms once their RO support ends, and continue until the end of their operational life. However, some generators have told us that their stations will not be economically viable without Government support.

We are conducting further analysis and assessment to better understand the issue, including the implications for consumer bills and the clean power mission. My officials are working with DEFRA to consider whether there is a case for intervention for biomass-fuelled stations, taking into account the electricity system and the supplementary environmental benefits that some stations provide. That work is in addition to the robust value for money assessments that we undertake to ensure any possible support is in the interests of bill payers.

I appreciate that Melton Renewable Energy and my hon. Friend the Member for South West Norfolk are looking for early answers, but I must stress that no decisions have yet been made and we are happy to continue the conversation with him.
