Conclusion (the committee's words)
We are not convinced the transitional support agreement between DESNZ and Drax provides good value for money for consumers. Government announced in February 2025 that it had agreed heads of terms for a deal to support Drax that will run from 2027 to 2031. The new support package means Drax will only be supported to operate for a maximum of 27% of the time, meaning that Drax will be operating less than half as often as it currently does. Government estimates that this will save each household around £6 a year. However, there was no element of competition in reaching this agreement and Drax will receive a higher unit price, albeit for a more flexible type of power, than some renewable power generators that won their contracts through competitive auctions. There have been suggestions that the current contractual arrangements may have allowed Drax to avoid making repayments to the government. The new agreement also requires Drax to source 100% of its fuel from sustainable sources (an increase on the current requirement of 70% which applies to all generators). The government has missed an opportunity to incentivise continued investment in BECCS in its transitional deal with Drax, which includes no mention of BECCS. Indeed, there have been recent press reports that Drax is withdrawing funding from carbon capture. 5 recommendation DESNZ should also consider how it can include clauses into the transitional support agreement to prompt Drax to begin transitioning to BECCS.

Summary written by Accountability Index from the government's response. It is not the government's own words.The government agrees with most of the Committee's recommendations on biomass, with target implementation dates between autumn 2025 and spring 2027, but disagrees on adding BECCS transition clauses to the Drax contract and says the KPMG reports are not a matter for it.
- On assessing its sustainability assurance approach, the government agrees, with a target date of autumn 2025, and says it is reflecting on evaluation and audit processes for the new Drax contract. It states the Ofgem investigation is evidence "the current assurance regime is working well".
- On a new oversight regime, the government agrees (target December 2025) and is "considering options to publish" its sustainability enforcement plans under the new Drax contract. It says any additional Ofgem oversight responsibilities "must be considered in the round".
- The government disagrees with adding clauses to the transitional support agreement to prompt Drax to transition to BECCS. It says such requirements would expose the government to "an unacceptable level of legal risk" until a full assessment of power BECCS is finalised.
- On the KPMG reports, the government says "This is not a matter for the government to consider", as the reports remain Drax's property and it is for Drax to decide whether to release them.
