Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of geothermal storage of energy from wind turbines on the mitigation of curtailment fees.

Clean Power will require greater levels of energy storage. Geothermal storage is relatively nascent but holds promise – particularly when there is demand for that heat nearby. We set out our ambition to unlock more flexibility from thermal storage in the Clean Flexibility Roadmap earlier this year and will set out our strategy for heat networks in the Warm Homes Plan.
