Electricity: Prices

Question: To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential impact of renewable intermittency on future household electricity bills.

Answer: Independent research confirms that renewables can cut electricity prices, having reduced wholesale electricity prices by up to a quarter (around £25/MWh) in 2024. The Department recognises the intermittent nature of renewables which is why we are investing in new long duration energy storage and flexibility. Increasing renewable deployment reduces system costs by lowering wholesale electricity prices and reducing reliance on fossil fuels.
