The UK government has decided to reduce subsidies for renewable energy generators by tying them to a lower inflation measure. This move aims to save taxpayer money and help lower energy bills for consumers. However, some investors believe it could undermine confidence in the market.
Starting in April, payments under the renewables obligation scheme will be adjusted according to the consumer price index (CPI) instead of the retail price index (RPI). Officials estimate that this change could save approximately £270 million a year by 2030, which they describe as a necessary step due to the subsidy scheme’s rising costs, projected to exceed £8 billion this year.
Officials emphasized that this approach seeks to balance the need for lower costs for consumers while still encouraging investment in the UK’s renewable energy sector. The Department for Energy Security and Net Zero noted that the previous RPI method was offering excessive compensation to energy generators, especially after inflation surged in 2022.
This update follows a previous decision in the November Budget to cover 75% of the domestic share of the subsidy costs through taxes rather than energy bills until 2029, helping to reduce household energy bills by around £88 annually.
Introduced in 2005, the renewables obligation scheme supports over 30% of the UK’s electricity supply. While it is no longer open to new participants, existing power generators under this scheme will continue to receive payments until 2037.
Many renewable energy producers opposed the recent indexing change, expressing concern that altering the terms mid-scheme could hurt investor faith, potentially raising the costs of future investments. Ross Grier, the chief investment officer at NextEnergy Capital, voiced disappointment over the government’s actions, suggesting they could negatively impact investor confidence in vital UK infrastructure.
Analysts from RBC noted that while the changes might not significantly affect energy costs, the potential harm to investor confidence could be substantial. In response, a spokesperson for DESNZ stated that these reforms aimed to deliver better value for money for consumers.
