Nascent technologies for decarbonisation will incur significant costs for taxpayers and consumers

Long-term consumer bill reductions from renewables seem inconsequential amid high wholesale prices

Government response. The government explicitly disagrees with the committee's (implied) recommendation, stating its focus is on consumer security by bringing down bills. It highlights past support schemes and its long-term strategy, Powering Up Britain, to deliver wholesale electricity prices amongst the cheapest …

The Department is also currently considering fundamental market reform of how electricity is bought and sold, through which it hopes to reduce costs of electricity to consumers over the long term. The Department expects reform of the retail market to result in more scope for suppliers to offer flexible tariffs, …

Government response. The government rejects the committee's observation, stating its focus is on consumer security by reducing and affording bills, and explaining its approach to policy interventions, cost impacts, and monitoring energy prices.
